I have the exact same issue here with my 1001px.

I found that if you do "sudo apt-get install pavucontrol" to install the PulseAudio Volume Control, and then lower the right channel of the microphone, the internal microphone then works.

The solution from Pablo in also solves the line-out issue for me too but, HOWEVER, then the internal microphone stops working even when using the PulseAudio Volume Control as described in the previous paragraph...

Any idea how to make both play along nicely?

The input section of the sound settings offer "Line in+Microphone1+Microphone2". None of them record any sound.

If I set options snd-hda-intel model=lifebook it works the output but doesn't work the microphone, if I set the model=basic it works the microphone if I plug the jack and set the type of input = line in, and works the output from the speakers but not from the headphone.
Any suggestion for any other kind of model that could make work both?

I played around with hda-analyser and 9.10 and it seems, that the initial mixer setting is not correct. The headphone output is not connected to the sound source.
Puting this line in /etc/rc.local is a work around:
#Bugfix für EeePC 1001PX
hda-verb /dev/snd/hwC0D0 0x1a SET_CONNECT_SEL 0x0c

This sets the correct connection for headphone output.
Does someone know how to correct this in the alsa configuration files?

I have tried Pablo's link. Headphone audio works great. Speakers work fine. Internal and jack microphones don't work at all. I've tried changing that one line in /etc/modprobe.d/alsa-base.conf to several different options to no avail. A speedy fix for this would be much appreciated.

Dima Krasner (dima-k) wrote :

Here's a workaround. Works 100% with my Fedora, 2.6.33.x and alsa 1.0.23.

1) Get hda-analyser:

This cute thing lists all pins, channels, etc'.

Run it and go to the 0x1a pin: unmute it (untick both)! That will ... unmute it.

2) Select "Audio Mixer [0x0c]" instead of d. That will assign the port to your output instead of input.

3) Reboot.

You can also try hda-verb as suggested above, but you'll still need to unmute the channels, you can get it in


buasaard (buasaard) wrote :

I tell you how I managed to make everything working : speakers only, earphone only, and built-in microphone. Tested on Skype and it seems it works everything.

Ubuntu netbook remix 10.04

Run Hda Analyzer
Go to 0x1a pin
set audio mixer to 0x0d
unmute vol[0] and vol[1] output
in widget control check all boxes (HP , IN, OUT)

Go to audio preferences , in output put the balance all on the right

All this with options snd-hda-intel model=lifebook in alsa-base.conf file.

The only problem is when restarting, must run hda analyzer again. Does anybody know how to fix these parameters?

I guess it's a problem with ALSA. I can't get this persistent either, I must run the hda-verb thing on each boot, manually, somehow it doesn't work when I put it in /etc/rc.local.

 Maybe the 1001PX needs a specific model in snd-hda-intel just like the 700 and 900 models. Kinda funny the 1005P doesn't suffer from this, despite of the fact both models are almost identical.

With Fedora I managed to get everything working, using hda-verb

Without any option in the alsa configuration file, writing into /etc/rc.local the following lines and rebooting.

/usr/local/bin/hda-verb /dev/snd/hwC0D0 0x1a SET_CONNECT_SEL 0x0c
/usr/local/bin/hda-verb /dev/snd/hwC0D0 0x1a SET_PIN_WIDGET_CONTROL 0xe0

In the audio preference, set as speakers and with balance on the left, works the headphone plugging the jack and the speakers unplugging, and of course works also the microphone.
I tried without any option in the alsa.conf file in Ubuntu, but it doesn't work.

buasaard (buasaard) wrote :

Gotcha! I managed to make everything working using hda-verb (or almost everything).

In alsa-base.conf file add

options snd-hda-intel model=fujitsu

Then using hda-verb

tar -xvjf hda-verb-0.3.tar.gz
cd hda-verb-0.3
sudo cp hda-verb /usr/local/bin
sudo gedit /etc/rc.local

add at the end before exit(0)

/usr/local/bin/hda-verb /dev/snd/hwC0D0 0x1a SET_CONNECT_SEL 0x0d
/usr/local/bin/hda-verb /dev/snd/hwC0D0 0x1a SET_PIN_WIDGET_CONTROL 0xe0

/usr/local/bin/hda-verb /dev/snd/hwC0D0 0x1a 0x390 0x00

save and reboot.

Now the last thing to do to have the microphone working is to put all the output balance either on the left or on the right. Oddily enough the microphone doesn't work with the output balance centered. So go to System-Preferences-Sound (or whatever, I have Ubuntu in italian) and put the balance on the left.

So can use voip and messenger application (tested with skype).

To hear music of course is better to center the balance.

If you set in the output as "analog headphone" the output works with headphone and if you unplug the headphone you can hear the speakers.

Sorry, of course not tar -xvjf hda-verb-0.3.tar.gz

Got everything working, even the microphone, Fedora 13.

I moved hda-verb to /usr/bin and added this to /etc/rc.local:

/usr/bin/hda-verb /dev/snd/hwC0D0 0x1a SET_CONNECT_SEL 0x0c
/usr/bin/hda-verb /dev/snd/hwC0D0 0x1a SET_PIN_WIDGET_CONTROL 0xe0

No "options snd-hda-intel model=something".

Now everything works perfectly and persistently. I can use my microphone, but for some reason the volume is very very high, I guess it's because I used hda-analyzer to reset everything to the defaults, probably one of the capture channels is at 100% and the Xfce mixer hides it.

Declining the Lucid and Maverick specific nominations for now and leaving this open against the actively developed Ubuntu kernel (which happens to be Maverick at this time). Will re-open the nominations should a fix be narrowed down which we can confirm specifically resolves this issue in Lucid and Maverick and qualifies for a Stable Release Update.

The output jack works with kernel, but the internal microphone stopped working.

Martín Ferrari (tincho) wrote :

I found something related to this: in my case (1001px-WHI050S), everything worked out of the box, and I *thought* the mic didn't work because of the balance issue. In fact, it works, but the mic in mono, and is converted into a stereo stream with one channel having the same values as the other, but with the polarity inverted. The result is that, when reproducing this with the mono output (the loudspeaker) both channels get mixed and therefore they cancel themselves.

The right fix for this would be to find the right register to change to make the mic a mono input, or to fix the polarity of one of the channels.

Can someone please change this back to confirmed as the internal microphone was working with RC versions of 10.10 but has since broken again with either ALSA or kernel updates.

Fresh install of Ubuntu Netbook Remix 10.10 (installed and updated 8/11 2010).
Problem with internal microphone presists, it does not work.
I've had no luck with any of the workarounds above.

I'm using Ubuntu 10.10 with the buasaard instruction, speaker, phone and internal mic work. Also I installed pavucontrol to balance mic channel one side. Cheese does not capture audio (int. mic) and skype does not allow to change sound settings. It's a known bug between skype and pulseaudio. So I start skype with "PULSE_SERVER= skype" and after all it works!

elvito (vitus-hanemann) wrote :

@ #43: it's not necessary to start skype withe the pulse_server argument. Just do the test call via skype with opened pulse volumecontrol and change in tab "Aufnahme" (I think it's called "Recording" in English) during the test call from "monitor..." to "Intern analog stereo". After that skype worked here like a charm.

I have 100 of the Asus eee 1001px machines out on a pilot program at the moment with 2000 of these machines being deployed next year. I REALLY need a fix for this - the pressure is really on now as this is essentially a trial of what will become a nationwide programme.

I did try the 2.6.35-RC1 kernel have had no joy as well as updated alsa drivers.

Let me know what you need from me to get this sorted.

By default (/etc/modprobe.d/alsa-base.conf untouched, no hda-verb nor hda-analyser):

Internal mono speaker works (good)
Plugging headphones:
- Headphones work (good)
- Internal speaker is silenced (good)
Unplugging headphones:
- Internal speaker starts sounding again (good)
Plugging microphone:
- Internal speaker is silenced, just as if the mic were a headphone (bad)
- Neither mic works (bad)
Unplugging microphone:
- Internal speaker works again (good, but it shouldn't have been silenced in the first place)

In all cases, the internal microphone never works.

FWIW, I have pulseaudio removed and purged, and I don't have any Gnome/KDE stuff running.

I just found out that the mic won't work from a cold boot, but once I suspend to RAM, it seems to be working fine after waking up.

Don't know if it's related, but the touchpad also acts up from a cold boot sometimes (unstable, jumpy cursor) and this gets fixed with a suspend-resume cycle as well.

@ #49

I can confirm the mic part. After waking-up it works fine.

Running Lubuntu 10.10 (with PulseAudio, kernel: 2.6.35-23-generic), suspend-resume did not work.

Nevyn (nevynh) wrote :

Is anything happening with this at all?

There appears to be two problems here:
1. I've not been able to get the microphone to work once - neither via external microphone or internal microphone.
2. Noise cancellation or something means that you have to shift the balance of the microphone essentially making it mono.

Now the question is, is anyone, anyone at all, actually working on this problem? Or are we sitting around hoping that something will change in alsa or the kernels?

So I'm at the same stage as Juan Gonzalez only I need this for 2,000 netbooks this year. If you're going to report something working, can you please provide full details? i.e. versions of applications (the kernel and alsa), what version of Ubuntu you're using etc.

I need this to be working in Lucid.

Unless someone is working on this without saying, I don't think anyone is.

For some reason this bug got declined for Lucid (Declined for Lucid by Leann Ogasawara) also Status says 'Fix Released' for some reason?

I have very little programing experience, but if there's ANY way I can help, please let me know.

Nevyn (nevynh) wrote :

Okay - I've had a bit more of a thorough look.

If I shift the balance all the way to the left, the noise stops. All the way to right and center, noise.

Looking at the source code there was something about nomicbias which I'm hoping addresses the balance stuff though I'd have to get something from the microphone to get an idea of the balance issue.

So how do I go about getting the sound card working? By the looks of the source code, the only thing that differentiates the different models are verbs and more specifically, the vendor specific pins. HDA-Analyser is next to useless in this regard as it doesn't describe anything about what can and can't be set with with those pins.

Does anyone know how hard it would get to get that information?

Nevyn (nevynh) wrote :

The other thing to note: The inputs show up in sound preferences as Microphone 1, Microphone 2 and Line-In. I checked the balancing trick on each Microphone and it appears they are treated exactly the same. I'm guessing that the two microphones are actually the one stereo microphone?

Juan Gonzalez (jglopez) wrote :

FWIW, here's my situation. Just updated today. Versions are:
Ubuntu Maverick 2.6.35-24-generic
alsa-base 1.0.23+dfsg-1ubuntu4
(Alsa only - I don't have pulseaudio nor jack nor any Gnome/KDE audio-related stuff installed.)

The computer is an ASUS 1001PX-BLK033S.

The internal mic does not work from a cold boot. After I suspend to RAM and restore, it just works.

I am using Audacity to test it. Doesn't matter if I set the input to stereo or mono under "Preferences"; both seem to work, but only after a suspend-restore cycle.

If set to mono, Audacity only picks up the left audio channel; if set to stereo, picks up the same signal on both left and right channels. No noticeable noise other than the CPU fan. So, after a suspend-resume everything looks OK.

However, If I plug an external mic then, the computer believes it is a speaker and disables the internal speaker, but the internal mic still works. So, plugging an external mic does not work yet.

#57 Doesn't work for me, using:

ASUS 1001PX-BLK044S (not sure what differs 44S from 33S)
Lubuntu 10.10, 2.6.35-24-generic
ALSA 1.0.23

I used to have pulseaudio installed, but purged it together with pavucontrol.
I've tried muting one channel and also tried using both, all tests done were done with Audacity.

I also have the same problem with external microphones, the computer treats it as a speaker/headphone and disables the internal speaker.

Nevyn (nevynh) wrote :

The internal speaker switching thing shouldn't be too much of a hassle to figure out. It's just a verb thing I think. At this stage, it's really important to try and get a microphone working (for my scenario) - I can play around with the rest once I've gotten that bit of functionality going. I'm going to play with 10.10 and see if I can replicate #57.

#58 - That's a bit more interesting. A slightly different version of Alsa which I wouldn't have thought would have made too much of a difference. It might be interesting to do a diff on the source code for that module.

I'm hoping that if I am able to replicate #57, then it might be interesting to see what the module does on wake up. Of course, that adds the complication in providing a patch and people having to compile it themselves (unless someone wants to make up a ppa for it).

Nevyn (nevynh) wrote :

*grumble* Unable to replicate. I have a:

I'm guessing at the very least our first 100 are 042W's (I haven't seen the new laptops yet so they could very well be a slightly different model number).

So this could very well be multiple bugs - what works on the 033S doesn't look like it's going to work on the 044S and 042W.

I'll see if I can come up with a likely patch for the 033S - though I won't be able to test so it may or may not work.

As for the other two models - I'm at a complete loss. I'm guessing someone would have already done this, but I'm going to have a go loading up the drivers with the various models and see if any of them work with a microphone. That'll at least give me somewhere to start from.

The important line seems to be the subsystem. I've asked our vendor to contact Asus about possibly getting some information on the model I've got. Can I get some more results from "lspci -v" pertaining to the audio device from those having issues?

This should enable us to get an idea of how many different revisions there appear to be for this sound card and hopefully means we'll be able to fix a range of them.

My lspci -vv report is exactly the same as #61 save for the IRQ line, which shows 45 instead of 46.

My 'lspci -vv':

Same as Juan Gonzalez, exactly the same result with an IRQ 45 instead of 46.

Include me on the list of people with speaker/mike woes on an Asus laptop. My machine is a K60IJ. I'm running Kubuntu 10.10 with pulseaudio installed and everything fully updated. The result of lspci -vv is:

so I'm an IRQ45 case with an SCO subsystem rather than an Asus one, according to lspci.

I have problems on both the input and output sides, but the input is worse. I cannot get the built-in mike to work at all. I've been fiddling with alsamixer, pavucontrol, etc., to no avail. I've tried muting one side, switching from mike 1 to mike 2, and several other things. Nothing seems to help.

On the output side, there's great confusion between the internal speaker and the headphone. Since I have the headphone jack connected to an external speaker system, that's the one I want to have work. I finally discovered that the necessary settings in the pulseaudio volume control are:

Output devices port: analog headphones
Configuration: analog duplex
alsamixer: front muted (to turn off internal speakers)
  Unmuting front turns on internal speakers but does not affect headphone output
Independent hp: off

It also turns out that after starting up the sound, the internal speakers are unmuted, but unplugging and replugging the headphones mutes them.

All the sound components work correctly in my Windows partition, so the problem is clearly with the Linux software.

Paul Abrahams (abrahams) wrote :

Addendum: I just discovered that the external mike works as Microphone 1. So it's only the internal one that's the problem.

Paul Abrahams (abrahams) wrote :

Further discovery: the internal speaker isn't totally muted, but it's operating at what I would guess is the 5% level. Not enough to be of any use, though.

By the way it is not possible to enable Wifi in this kernel .. but this is, I think, different bug
when I start PC with Wifi enabled .. wifi works .. but it's not possible to turn it on (with Fn+F2) if started without

I have also another bootup option with kernel: "Ubuntu, with Linux 2.6.32-25-generic"
here Skype works.. I use

and here also turning ON/OFF of WiFi works

On the bottom of your computer, where you'd find your serial number, it'll say something along the lines of:


The 042W seems to be kind of an indication of sub-versions or revisions. I'm looking to be able to map the different models to the type of sound card they have (i.e. the different models appear to have a slightly different implementation of the sound card).

So there are all sorts of "solutions" or "work arounds" for the 1001px but it's not clear what version of the sound card these work on. So if we can get an idea of what does and doesn't work, on various revisions of the sound card, we should be able to come up with solutions.

So those people who can load up snd-hda-intel with model=fujitsu and use model=lifebook to get the microphone and headphones working respectively is probably just a matter of looking at the verbs.

Those where sleep works, is probably a case of looking at the source code to see what happens when they wake up.

And those like me, where I'm unable to confirm whether the microphone works at all (i.e. there has never been a scenario where I've had the microphone working at all). This is probably going to require figuring out if any of the vendor pins need to be used and trying to reverse engineer them or getting information out of Asus about their implementation.

So it's kind of important to figure out what models there are, which laptops they affect, and what solutions work for which models.

I've started charting the issues we're seeing.

If anyone has a 1001px WHI050S - given that an earlier report shows it to work out the the box bar the balance issue - I'd really like to know if I'm on the right track in terms of the sub system pci id's.

And if anyone else can help me complete this picture:
I need:

Full model number of laptop (at the bottom of the laptop on the same sticker as the serial number)
The full output of the subsystem line from running "lspci -vv" which pertains to the Audio device.
If any prior workarounds have worked for you.
If you have tried all of the suggestions on this bug report.

And please don't reference other messages while doing this as it makes it a little awkward. IRQ's shouldn't be important here so feel free to omit that detail.

@Everyone else
I'm unable to flash the BIOS (as an anti-theft measure, the BIOS has been locked by the vendor on the machine I have so that if it is stolen, the image asking people to call the support line if they have received the laptop isn't removable). So can someone have a go at flashing their BIOS with the latest version (I've currently got 0904 on this laptop but it should be 1104) and confirm whether this exhibits the behaviour Juan has described:
Running linux-image-2.6.35-23, with alsa-base 1.0.23. Putting the computer to sleep and waking it up seems to make the internal microphone work. The external microphone still isn't working but this shouldn't be too hard to figure out once we've got the internal mic working (hopefully).

Checked my BIOS, I've got 0802 (build date: 24/06/10)

Haven't come around to flashing it yet since I've been busy.
Is it possible to backup the BIOS or some other safety precautions I should take before going forward? (never flashed BIOS before)

No PulseAudio. Suspend & resume does not work. Microphone balancing (100% left, 0% right | 0% left, 100% right) does not work.

Additional comments: I've got a 'Realtek ALC259' chip (not sure if that's been said before, or if it's of any use at all)

Good news! Managed to duplicate Juan's suspend/restore solution.
What I did:

1) Updated BIOS to 1102 (not sure if this step was needed, since I never tried step 2 before)
2) Followed these instructions for the latest drivers:
3) Reboot, suspend & resume now enables the microphone.


*No PulseAudio installed.
*Alsamixer now shows my chip as 'Realtek ALC269VB' (used to say ALC259).
*Microphone works fine in Audacity and Skype.

Still haven't gotten the headphone/microphone port working properly though I believe (unconfirmed) headphones at the very least work.

Unfortunately, this also means I'm going to have to compile for each kernel release. Don't want to use dkms in this case as the compile time is fairly high.

So linux-image-2.6.32-31 is required. This is for Lucid. Could solve other sound card issues? Wasn't discriminant when compiling.

Speakers works fine. Headphones works too - you don't need to do anything.
External microphone doesn't work now, but I don't need it.

If somebody needs additional information about my 1001px just let me know.

I've bought my Asus 1001px one year ago and all that time I coudnt use the internal microphone.
