Same issue here on asus F555U. How to resolve it?

[Riyafa Abdul Hameed (riyafa-q)]

My kernel is 4.2.0-27-generic

[Hui Wang (hui.wang)]

@Riyafa,

Please upload the alsa-info.txt generated on your machine.

Please refer to https://wiki.ubuntu.com/Audio/AlsaInfo

[Riyafa Abdul Hameed (riyafa-q)]

I have attached the alsa info here

[Hui Wang (hui.wang)]

This bug is for headset microphone, after the headset is plugged in, the headset mic can't be detected.

I don't know if your problem is same as this one or not.

Anyway test this dkms.

$sudo dpkg -i oem-audio-hda-daily-dkms_0.1_all.deb
$sudo reboot

redo the test to see if it can fix your problem.

[Riyafa Abdul Hameed (riyafa-q)]

Now the "Headset Microphone" is shown in the sound settings, but it doesn't seem to capture any sound.

[Riyafa Abdul Hameed (riyafa-q)]

I installed ubuntu 16.04. What is the driver I could use on it? The given driver doesn't work

[Riyafa Abdul Hameed (riyafa-q)]

I installed ubuntu 16.04. What is the driver I could use on it? The given driver doesn't work. Now the kernel is 4.4.0-22-generic

[Hui Wang (hui.wang)]

If the problem is not fixed in the mainline kernel, It will have the same result no matter what drivers you try.

Do you still remember what testing steps you performed for the comment #9?

[senya (senya)]

Besides this I also have an issue with automatic detection of headphones plugging. May that be related? If I manually point pavucontrol to headphones, they work fine, but still being shown as "unplugged".

I tried installing oem-audio-hda-daily-dkms from https://launchpad.net/~ubuntu-audio-dev/+archive/ubuntu/alsa-daily/+packages and that didn't help.

@senya,

There are lots of error logs in the dmesg:

Let us temporarily move the /lib/modules/4.4.0-36-generic/kernel/sound/soc to a place, e.g. $sudo mv /lib/modules/4.4.0-36-generic/kernel/sound/soc ~/;sudo reboot

Then test if headphone detection works fine or not.

And you can restore that folder to the original place anytime you want.

If move the folder soc/ does not help to fix headphone detection problem, Please also generate alsa-info.txt, this time please generate two, one is generated without headphone plugged, and another is generated with headphone plugged.

thx.

[MIFAS (mmifas)]

I've same laptop and 16.04 with latest update. My alsa log file
http://www.alsa-project.org/db/?f=37fccb98d36632887b82b768157dca2a46d817d3

I've the same issue. Sound working in laptop speaker. When I plugged in the headset, sometimes sound coming though both. I can configure in alsamixer. But That is not propper solution at all. And MICROPHONE NOT WORKING AT ALL.

[senya (senya)]

@ hui.wang, I don't have this laptop currently with me. Probably I'll be
able to test this only after a month. Thanks for help!

[Hui Wang (hui.wang)]

@mmifas,

About your comment "When I plugged in the headset, sometimes sound coming though both. I can configure in alsamixer", in that situation, the sound is supposed to be played through headphone, so could you please generate 2 alsa-info.txt, the first one is generated when problem is reproduced, the second one is generated after you use alsamixer to workaround this problem.

thx.

[MIFAS (mmifas)]

@hui.wang

This is before changing the alsamixer and before plugged in the headset
http://www.alsa-project.org/db/?f=d2bc312661205b5868695b5c23a669720ac1fe5d

This is after changing the alsamixer and plugged in the headset(sound coming though speaker and headset)
http://www.alsa-project.org/db/?f=073766b215d6845aec7e4a26a012c1d48571cb31

This is after reduce the speaker volume to 0.( Now only headset is working)
http://www.alsa-project.org/db/?f=15e4fb459a359ad064051af59be92088eef12512

[Hui Wang (hui.wang)]

@mmifas,

According to the alsa-info.txt of the #20, it looks like the audio driver did not detect the headphone/headset plugging event at all, if it detects the plug/unplug event, the pulseaudio will automatically switch the output from the speaker to headphone, don't need you to manually change the alsamixer stuffs.

I guess after you plug in the headphone/headset, the output still only comes from speaker, then you use some way (like using the pavucontrol mentioned in the #13) to let the headphone work, but the driver and pulseaudio still think the headphone is not plugged, as a result the sound will be played out both from the speaker and headphone.

Please check /proc/interrupts on your machine, and notice the line end with the key word snd_hda_intel, this is the interrupt count for sound driver, plug and unplug the headset/headphone, let us see if this will trigger interrupt or not.

thx.

[MIFAS (mmifas)]

I've something like this
 131: 54 0 66 0 IR-PCI-MSI 514048-edge snd_hda_intel

[Hui Wang (hui.wang)]

After plugging or unplugging the headset, does the number in the #22 increase, if it does, it means the plug/unplug can trigger the interrupt, otherwise it can't.

thx.

[MIFAS (mmifas)]

I'm not sure when its increasing, I tried couple of times, value doesn't change. This is current value
131: 17 10 1810 184 IR-PCI-MSI 514048-edge snd_hda_intel:card0

[Hui Wang (hui.wang)]

It seems the plug/unplug the headset can't trigger the interrupt.

Please run $sudo hdajacksensetest -c 0 -a

Then plug the headset,

rerun the $sudo hdajacksensetest -c 0 -a

And upload the output of the above to launchpad.

BTW, does the internal microphone work on your machine?

[MIFAS (mmifas)]

sudo: hdajacksensetest: command not found

But I've installed hdajackretask

[Hui Wang (hui.wang)]

sudo apt install alsa-tools

Then you will have this command.

[MIFAS (mmifas)]

This is before plug the headset

Pin 0x13 (Not connected): present = No
Pin 0x14 (Internal Speaker, ATAPI): present = No
Pin 0x18 (Pink Mic, Rear side): present = No

This is after

[Hui Wang (hui.wang)]

@mmifas,

Thank you for your testing result, and It looks like the headphone (0x21) can't detect the plug/unplug. I have no idea why this happened.

I already asked for help from Realtek technical expert, he suggested we turn on the hidden register (0x20), then generate an alsa-info.txt.

To do so, please follow the steps as below:

1. sudo echo 1 > /sys/modules/snd_hda_codec/parameters/dump_coef

2. generate a new alsa-info.txt and upload it to launchpad. (refer to #14).

Thanks.

[MIFAS (mmifas)]

When the fixed gonna release?

[Hui Wang (hui.wang)]

There is no fix yet. And realtek engineer told me that he met the similar problem on the Dell laptop before, but it was proven a hardware problem (headphone can't be detected).

So does the headphone work well under Windows on your machine?

[MIFAS (mmifas)]

Perfectly working on Windows.

[MIFAS (mmifas)]

I've Dell 5000 Series, And sound card model is ALC3234, In that laptop, When I plug the headset, A dialogue is a popup, Unknown Audio device(see the attachment), Then, When I select Headset, the headset is working, Likewise, Can't you give us a fix like that?

[Hui Wang (hui.wang)]

They are different, on Dell laptop, the audio jack can detect the headphone plug/unplug, this is the pre-condition for fixing the headset-mic problem.

But on your Asus laptop, the audio jack can't detect any plug/unplug, so even apply the same fix to this machine it will not work.

[MIFAS (mmifas)]

Windows is detecting audio jack, so why ubuntu can't detect?. BTW Sometimes In ubuntu, audio jack is detecting. Don't say this is laptop issue.

[Hui Wang (hui.wang)]

Then please dump coefficient as #29, I will send it to realtek's engineer and let them have a look.

thx.

[MIFAS (mmifas)]

Hi

As you say, I've generated new alsa-info.txt. Please check the below link
http://www.alsa-project.org/db/?f=7bc43606415f0a0a2e459a7504a7d8b348895507

Please do the need full

Thanks

[Hui Wang (hui.wang)]

Sent the alsa-info.txt with coeff (#37) to audio expert of Realtek.

[Hui Wang (hui.wang)]

Please install this dkms and reboot, then test if mic can work or not.

[MIFAS (mmifas)]

Not working. It's only working when I add the following line in /etc/modprobe.d/alsa-base.conf file

options snd-hda-intel model=laptop-dmic

And Also I need to manually change to Internal Microphone through Sound Switcher Indicator - version 1.2.2

[Yuriy (ort00gon)]

Ubuntu 16.04 LTS on ASUS F555U jack is not detecting connection, but the mic problem is solved as in (#40)
