Title: amixer: Unable to find simple control 'Master',0
Post by: theeast on 23 November 2022, 15:36:46

I've just installed ArtixLinux base on my MSI Alpha 17 B5EEK and everything works fine except the audio. For some reason, Amixer won't show Master control and I don't have any sound. I have installed alsa-lib alsa-topology-conf alsa-ucm-conf alsa-utils. Here is Amixer's output

Code: [Select]

Simple mixer control 'IEC958',0

Here is aplay -l output

Hello,

Have you tried setting the sound card to use?

I think you know the procedure, but I list below my modest notes which could possibly be useful to other readers of this forum :

**********

To list sound cards:

Code: [Select]

cat /proc/asound/cards

 0 [HDMI           ]: HDA-Intel - HDA ATI HDMI
                      HDA ATI HDMI at 0xfce60000 irq 96
 1 [Generic        ]: HDA-Intel - HD-Audio Generic
                      HD-Audio Generic at 0xfc900000 irq 98

Then to define card 1:

Code: [Select]

your_text_editor ~/.asoundrc

Code: [Select]

nano ~/.asoundrc

And in my case, I specified this:

Code: [Select]

defaults.pcm.card 1
defaults.ctl.card 1

*********

I had similar issues with pulseaudio.

It's been two years since I removed all pulse packages except libpulse and libcanberra.

I use alsa and the nice and very practical qastools mixer on different pc :

Note: I don't play games and don't use wine or steam.
But I have sound in all my apps.

@tintin Creating /etc/asound.conf with similar content resolved my problem despite there still being some weird janky stuff.

Thank you!
