[Dell Studio 1558] Driver advertises extra internal Microphone Input which does not work

[Joshua Rubin]

Binary package hint: pulseaudio

Using alsamixer, I can select "Input Mic 1" on my Intel sound card (snd_hda_intel) using alsamixer, but pulse does not see it. Pulse does see "Analog Microphone" (selects alsa "Mic"), "Internal Microphone" (selects alsa "Internal Mic") and "Analog Line-In" (selects alsa "Internal Mic" as well). As none of these are alsa "Input Mic 1", I can't get the microphone to record without going to alsamixer.

[David Henningsson (diwic)]

Hi Joshua, could you elaborate a little on what inputs you actually have? According to BIOS, you have two internal mics and one external mic jack. According to http://www.dell.com/us/p/studio-1558/pd this machine has one mic jack and one line-in jack.

Could you explain what physical inputs connect to 'Internal Mic', 'Mic' and 'Internal Mic 1' at the alsa level?

[Joshua Rubin (rubixconsulting)]

David,

I do have three mic inputs. One on the top of the monitor, one below the touchpad and one 1/4" input. The only mic that I have ever confirmed works is the one above the monitor.

Alsamixer shows two tunables, "Input Mixer" and "Input Mixer 1". Each of those items have the following values to choose from:
* Internal Mic (below touchpad, never seen work)
* Mic (never tested)
* Internal Mic 1 (above monitor)

Pulse shows the following values (which map to the values in parens in alsamixer on the "Input Mixer"):
* Analog Microphone (alsa => Mic)
* Internal Microphone (alsa => Internal Mic)
* Analog Line-In (alsa => Internal Mic)

Pulse does not change the second alsamixer "Input Mixer 1".

Switching between "Internal Microphone" and "Analog Line-In" does change some mixer levels, but not the alsa input.

Since there is no way for me to switch to "Internal Mic 1" via pulse, it makes it seem that I have no working mics.

Let me know how else I can help.

Thanks,
Joshua

[David Henningsson (diwic)]

Hmm, could you try this: https://wiki.ubuntu.com/Audio/InstallingLinuxAlsaDriverModules - I know there has been a rewrite of the internal mic handling lately, perhaps that would help?
Unfortunately those changes won't reach natty, so an option could be to try to disable 'Internal Mic' in the hope that it would turn what is now 'Internal Mic 1' into 'Internal Mic'.

[Joshua Rubin (rubixconsulting)]

David,
That PPA does not have natty packages so I can't try it. Do you have any other suggestions?
Thanks,
Joshua

[David Henningsson (diwic)]

> That PPA does not have natty packages so I can't try it.

Ah, sorry. And the DKMS stuff isn't really ready either so let's skip this idea for now.

> Do you have any other suggestions?

Well, the best thing I guess would be if we actually get the first internal mic working. Could you try
1) installing snd-hda-tools from ppa:diwic/ppa (I'll upload a natty version of that package later today)
2) Make sure "internal mic" is selected in alsamixer (not "Internal Mic 1")
2) run "sudo hda_analyzer"
3) go to node 0x0b
4) make sure Input amps are turned up, and experiment with different values of "VREF" and see if that helps.

[Raymond (superquad-vortex2)]

according to 92HD73C datasheet

1.4.11. Multi-channel capture
        The capability to assign multiple ADC “Input Converters” to the same stream is supported to meet
        the microphone array requirements of Vista and future operating systems.

[Joshua Rubin (rubixconsulting)]

David,

I have the following VREF options, none of them got the mic working:
* HIZ
* 50
* GND
* 80
* 100 (when I select this, it reverts to HIZ)

I do have two alsa inputs "Input Source" and "Input Source 1". The working mic ("Internal Mic 1") does not work if I set that as the source on "Input Source 1", in fact, nothing works on "Input Source 1". The only working combination I can get is "Internal Mic 1" on "Input Source".

Do you have any other ideas?

Thanks,
Joshua

[David Henningsson (diwic)]

We could try disabling the mic that is not working, although that would feel a little like partial failure, it would still be better than current state.

To try this, first make sure no audio applications are running, including pulseaudio:

echo autospawn = no >> ~/.pulse/client.conf
killall pulseaudio

Here are the commands to perform the change:
sudo -s
echo 0x0b 0x4f0000f0 > /sys/class/sound/hwC0D0/user_pin_configs
echo 1 > /sys/class/sound/hwC0D0/reconfig

to restart pulseaudio afterwards, delete ~/.pulse/client.conf - then start your recording program and retry.

As for 'Input Source 1' btw, that's connected to a separate ADC input channel that's not usually used.

[Joshua Rubin (rubixconsulting)]

David,

Thanks for the help. After doing that, I have the following results after setting pulse input connnector to:
Analog Microphone -> 100 volume on alsa "Mic", 0 volume on "Internal Mic" (the mic still pics up some sound at a low level though)
Internal Microphone -> 100 volume on alsa "Internal Mic", 0 volume on "Mic". Working as hoped.
Analog Line-In -> 0 volume on alsa "Internal Mic", 0 volume on "Mic". Untested otherwise.

How do I make this change permanent? I assume it resets on restart?

Thanks again,
Joshua

See http://www.kernel.org/pub/linux/kernel/people/tiwai/docs/HD-Audio.html#_early_patching for how to create a configuration file, i think it should look like this:

[Tao Huang (greatht)]

Any progress on this bug?

I just upgraded to Natty last weekend and find that my internal microphone(the little one beside the camera) doesn't work anymore.

It used to be working under Maverick, and currently I can only enable it through alsamixer. It is quite annoying. :(

[Rodrigo Primo (rodrigosprimo)]

Hi,

I guess I have the same issue. I also have a Dell Studio 1558 and the internal microphone (the one beside the camera) stopped working after I upgraded to Natty.

I never had problems with the internal microphone before on Maverick or previous versions.

How to enable it through alsamixer?

Let me know if there is anything I can do to help.

Thanks

[Tao Huang (greatht)]

Hi Rodrigo,

Following these steps to enable your internal microphone:
1. start alsamixer in a terminal
2. Hit "tab" or "F4" to switch to capture configuration
3. Hit right arrow key 3 times to select "<Input Source>"
4. Hit Up/Down arrow key several times to select "Input Source [Internal Mic 1]" as your current input source.

This is just a temporary solution and you will have to do this gain once you reboot your machine :(
We will have to wait till ubuntu engineers solve this bug. Hopefully soon.

[Frank Sullivan (sullivan-math)]

Many Thanks to Tao Huang for "solving" the internal mike compatibility with Skype under Ubuntu 11.04. I have been
fiddling for several days with various attempts (alsamixer, pulseaudio, Sound Preferences, etc.) , but the simple and clear explanation provided for Rodrigo also worked on my Dell Laptop. As often happens, it seems easy and logical once someone explains the steps, but without that help it's even easier to stumble around in the dark.

[userdce (userdce)]

Please somebody look into this bug.

[Mariano (noinflection)]

Having same problem over here (ubuntu studio 1558)

[saulo (saulo-venancio-gmail)]

SAME PROBLEM HERE

[David Henningsson (diwic)]

After having done some more research about it - and having access to an actual machine - it seems the easiest way to solve this bug would be to edit /etc/modprobe.d/alsa-base.conf and adding the line:

options snd-hda-intel model=dell-m6-dmic

Then reboot. That will remove one internal mic and leave the correct one still there.
For reference, this was used on PCI SSID 1028:0413.

[David Henningsson (diwic)]

I'm currently travelling but I'll send a patch to upstream some time next week hopefully.

[David Henningsson (diwic)]

For the record, I tried what I could to get the "extra" mic working but couldn't - probably there is no mic in the hole, and if there is, we don't know how to enable it, so the resolution is to disable the mic - that isn't even advertised by BIOS but by the driver. (!)

[David Henningsson (diwic)]

Upstream accepted patch, it'll reach Natty some time later on.

[Wesley Velroij (velroy1)]

So the fix will be in the updates soon? I yesterday installed Kubuntu 11.04 after solving my freezing issue, but then i also discovered this bug. If i add that line what you said will it be fixed to then?

[David Henningsson (diwic)]

@Wesley, if you want it in -updates soon, please follow instructions here: https://wiki.ubuntu.com/KernelTeam/KernelUpdates
Otherwise see comment #19 which should be a relatively quick and simple workaround.

This bug is awaiting verification that the Lucid kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed' to 'verification-done'.

If verification is not done by one week from today, this fix will be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Thank you!

[Herton R. Krzesinski (herton)]

The commit for this issue in Lucid came in via a stable upstream release (2.6.32.42). As such it is not subject to the standard bug verification process.

[Herton R. Krzesinski (herton)]

The commit for this issue in Maverick came in via a stable upstream release (2.6.35.14). As such it is not subject to the standard bug verification process.

[Brian Burch (brian-pingtoo)]

Until very recently, I had never needed to use the microphone on my Dell Studio 1558. Then I discovered it did not work under 11.10 Onieric. I confirmed the bypass of redefining the active microphone with alsamixer worked, indicating that pulseaudio was choosing the "wrong" microphone to make active.

In case anyone is interested, the microphone is working well under the 12.04 Precise Pangolin Beta. I presume the appropriate quirk was integrated into the 3.2.0-17 kernel.
