[SOLVED]Alsamixer - the "mute" option for the Master volume is missing

Andy_Crowd · 2014-07-29 16:39:18

Hej!
After the recent update the Mute option is missing for the Master volume but I can mute sound for PCM.
My sound cards:
0 snd_cmipci
1 snd_hda_intel

amixer -c 0; amixer -c 1

There is always the softvolume plugin. What have you updated recently? (pacmans log)

Edit: lost a word.

Key "M" is missing ?

Andy_Crowd · 2014-07-29 22:27:58

Yes the "M" is missing.
I can use amixer -c 0 set Master 0 but not amixer -c 0 set Master toggle. It shows no errors either.
This is working without any problems: amixer -c 0 set PCM toggle

Which cmi is it?

Andy_Crowd · 2014-07-30 06:01:15

Multimedia audio controller: C-Media Electronics Inc CMI8738/CMI8768 PCI Audio (rev 10)

Pacmans log is //var/log/pacman.log, help out a little, what did you update? The cmipci.c in linux_source/sound/pci/ might have changed or something withing alsa packages. I checked recent changelogs on the alsa wiki, only one mentions CMI, but not your model and there is nothing about controls. What configuration do you have for alsa/modprobe/anything else audio related? (~/.asoundrc, /etc/asound.conf, /etc/modprobe.d/*alsa*)

Andy_Crowd · 2014-07-30 14:06:46

In the /etc/modprobe.d/alsa-base.conf

options snd_cmipci=0
options snd_hda_intel index=1

And nothing more

What is that supposed to achieve? You probably meant:

options snd_cmipci index=0

Andy_Crowd · 2014-07-30 19:11:34

Those settings are the same.

Mute shows only when I am installing pulseaudio.

Okay, can you provide documentation/reference to back that up? Should you mean, there is no difference in how you system behaves, yes, that is very likely, since the second line is correct, so the cmi would be at index 0 either way.

In alsamixer? PA runs on top of alsa, so the controls for alsamixer should stay the same. Do you mean another mixer maybe?

You still did not provide the relevant part of pacmans log and amixer output for both cards. Are you certain you used the cmi as default the whole time? Is the snd-hda-intel a hdmi sound card?

Andy_Crowd · 2014-07-30 19:43:50

Ok. The problem is solved, I have tested with a Linux Mint Live CD and got the same problem:

Master Mute (MM) is missing in the alsamixer
for C-Media CMI8768 7.1 Chanel PCI Audio

Now I must find a better one that will work with Linux without any troubles or use the pulseaudio for getting Mute for the Master volume.

Can be used for hotkey amixer set PCM toggle instead of amixer -c 0 set Master toggle, the -c 0 is not necessary to use in the command line, it is just for choosing of the sound card index, by default is -c 0 used.

I recommend using card name references instead of numbers. To get those run:

$ cat /proc/asound/card*/id
SB
PCH
HDMI
# then use
amixer -c HDMI # for the index=2 card

I just tested it, you can add a mute switch by using softvol plugin with resolution set to 2:

pcm.test {	type softvol;
		slave.pcm "default";
		control {	name "Test";
				card HDMI;	}
		resolution 2;	}

Then the following will toggle the mute switch:

amixer -c HDMI sset Test toggle
