Huawei MateBook 14 AMD 2021 no sound with patched kernel

[Alexey336]

First of all big thanks for your work. It seems like driver was loaded. I can change the volume level, I configured alsamixer the way wiki says but still can't hear anything

There is also no way to enable Left Headphone Mixer Left DAC and Right Headphone Mixer Right DAC in alsamixer

Also upload the output from dmesg command.

I don't see anything wrong in the kernel logs, seems the driver loaded fine. Please run the command alsa-info and attach the output here.

There is also no way to enable Left Headphone Mixer Left DAC and Right Headphone Mixer Right DAC in alsamixer

Looking in the alsa-info output there are 3 issues:

• The Headphone Mixer knob is zero, it should be increased, just set it at max
• Left Headphone Mixer Left DAC is not enabled
• Right Headphone Mixer Right DAC is not enabled

Now you said that you can't enable Left Headphone Mixer Left DAC and Right Headphone Mixer Right DAC how did you try to enable them in alsamixer?

[Alexey336]

It's just inactive in alsamixer, I can't switch it. Same for Right Headphone Mixer Right DAC

[codepayne]

how are you activating these switches, what buttons are you pressing?

[Alexey336]

I tried with space, enter and arrow buttons

[Alexey336]

Lol I just found that these sliders enables with M button and sound now works
