[SOLVED] Internal Sound or internal microphone [Solution in post #8]

capitanito · 2020-07-04 18:41:11

Hello Archers,

### MY PROBLEM ###
I'm on Arch for some weeks now and love it but the journey has recently begun.
Two days ago I wanted to try out if zoom works because I needed it and figured out that the internal microphone was not registered inside system.

### QUESTIONS FOR MORE INFORMATION ARE WELCOME ###
It is my second post and I hope that I posted everything that has to be inside of a post of this kind. Keeping in mind the respective sticked thread about what should be inside a post my logs et cetera are all at the end of this post if they were not mentioned before. Also if there is something missing just tell me and I will post it.)

### WHAT ALREADY HAPPENED ###

After some digging I figured out, that there is a file /etc/modprobe.d/disable_dmic.conf with the follwing content:

 options snd_hda_intel dmic_detect=0

As I found out there were some trouble about this with the Kernelversion 5.4 - not only in Arch systems.

Anyway I installed the sof-firmware package via pacman (actually I don't remember the exact point when I did it but at the moment it is installed). The were some similar issues with (not only but surely) hp, dell and acer modells (mostly relatively new models and the Realtek ALC285, as it is in my case, or similar). After installing the Package I was able to see some recording devices in alsamixer, which was not the case before. Therefore I think it was part of the solution.

Now the thing is when I comment out the only line of this file, save it and reboot I am acutally able to use the internal microphone and it also works with a bluetooth headset (sound and microphone instead of only the sound; unfortunately I have no wired headset around at the moment for testing) but the internal speakers do not work in any way in this case.

Well now I got the problem in a cage but wanted to find out what is actually the difference between the two cases and started some analytic stuff using mainly but not only the Arch Wiki, some documentations and a bunch of forums. Now I got to a point where I found a difference:

using the command hwdetect --show-modules I got a difference (see full codes at the end of this post in the CODES - section):

With options snd_hda_intel dmic_detect=0 active at startup and therefore working internal speakers but no microphone support (from the tested ones internal and bt headset):

snd-hda-codec-generic
snd-hda-codec-hdmi
snd-hda-codec-realtek

Which is not part of the output with #options snd_hda_intel dmic_detect=0 inside of the forementioned disable_dmic.conf file. But in this case the microphones work and also does the BT Headset sound. In this case i have the following active modules instead of the three mentioned above:

snd-soc-dmic
snd-soc-hdac-hdmi
snd-soc-skl_hda_dsp

What I did not test yet is HDMI support in any of the cases but I think I will be able to do so in the next few days.

What I also observed is that I get an audio-signal during the playback of audio inside of pavucontrol but the speakers keep muted.

Just to be clear: I alredy checked alsamixer, pavucontrol and the audio settings for inputs and outputs in both cases ...
But maybe the is a hint what I did not do for now (actually I am quite impressed how many options exist to manage audio devices).

I just wanted to share this up to this point because I did not find this in a forum yet as far as I reached and if it helps at least one single person to solve the same problem much faster it is worth it.

My next steps will be informing myself about the modules as I am relatively new really diving into the world of Linux and not just having it as a dualboot that I just use for some time and go back to Windows OS.

Maybe there could be some sort of advice how I can get solved this faster but as said for now I did this post mostly for public documentation of the issue and I will keep you updated as I go foreward.

I hope that I am on the right track to hunt down the problem. If I should take something else in count I would be glad for any advice

You didn't create this file? Where did it come from?

I don't know. I made the Arch install about one month ago and most things worked fine. And I was not bothering myself about that topic as everything worked out.
But as I wanted to do recordings I started to wonder why this is the case and at some point I found that file but I did not create it ...

Possibly I simply forgot that I created this file when I did it right after setting up the system. In this case it's just a workaround that solved one problem in change for another one ...

As I said it still is my first serious approach to live just on linux and at the time I set up the system I was new and just happy when things worked. I am still learing about the whole Linux world.

I expect to give some Updates (HDMI testing et cetera) during the upcoming week.

Another (maybe related) issue is that all the keys for screen brightness, volume control and so on worked out of the box except for the microphone mute key (F8 on the keyboard; actually it is F20).
This does not bother me that much and as I have read in some research it can be resolved with a remapping of this specific key but at the moment I am focusing on the naked ability of the system to work properly than diving into stuff like key remapping to solve a comfort problem.

And maybe the solution for the topics problem fixes this failure too, which I prefer in comparison with a workaround through the remapping of the keys.

If I were you I would try another distro like Ubuntu and see if the problem is still there.

capitanito · 2020-07-04 23:18:04

Do you think testing it using a live-USB stick is enough ?
Do you recommend Ubuntu as a non Arch based distro or would it be a better attempt to try manjaro ?

In any case I will give it a try and post the results

Hey there,
don't know whether you have solved your problem yet, but I've been through the same thing with my HP ZBook 15 G6 in last few days.

Definitelly remove this line:

options snd_hda_intel dmic_detect=0

so that the legacy driver is not loaded - you won't see any mic with the legacy driver loaded, since the mic input is exclusivelly digital.

After applying changes, open the alsamixer, switch to the sof-hda-dsp soundcard using the F6 key and check, whether the Master channel is unmuted (press M key to unmute) - it is muted by default and it is easy to overlook, since the audio does not unmute automatically after cranking up the volume.

Source: https://wiki.archlinux.org/index.php/HP … u_G6#Audio
(With the current kernel and sof-firmware package, you don't need to edit the /etc/pulse/default.pa file.)

After reboot, the audio will be muted once again. To make unmuting persistent, run this command:

alsactl store

@JKos
Actually I was occupied with some other stuff and was not able to do all the testing I planned to do (actually I tried out some distros but did not take me the time to write everything in a detailed way; It worked in one of 4 tested distros from a live usb drive but I do not even remember which it was ...) and I just used the legacy drivers as it worked out for what I needed at the moment, but:

I did what you told me to do and it worked out (just tried it without the persistence but I assume that it will work and only mention it if it will not). I do not know why I did not get it working when I was playing around with alsamixer (in one case there was a Master Volume that did not turn on by using the M key.
Anyway I realized some (short) time ago that there was a Kernel Update while I was just doing a reagular update of the system. I assume that this fixed it.

Thanks a lot for your help. As a result I will assign this thread as solved *thumbs up*

Solution working for my system (hp EliteBook x360 1040 G6) and as mentioned also for hp ZBook 15 G6

Thanks to JKos for the providing the solution and the respective links:
