No sound from ASUS Essence STX 2 on Debian Buster

[skolkerom]

Good day.

I have newly installed Debian Buster and ASUS Essense STX 2 sound card.

The problem is that there is no sound from speaker, althouth pavucontrol shows, that audiostream is ok.
I tried to select all outputs one by one(Headphones1, Headphones2, Speaker) with no success.

Alsamixer:


Pulseaudio:


What can I do to debug that problem?

Please, help and thanks in advance!

Can we see

Code: Select all

aplay -L
lspci -knn | grep -iA2 audio

Have you tried un-muting the "Analog I" output in alsamixer?

I have tried to unmute Analog Input just now - same result. It is actually input, not output, so the result is expected, I think.

Thanks for so quick reply!

[Head_on_a_Stick]

It is actually input, not output

D'oh! So that's what the I stands for...

The card has a kernel driver and PA knows about it so I'm a bit confused here

We could try some non-free firmware, I suppose:

Code: Select all

# apt install firmware-linux

[skolkerom]

I just realize that I don't hear specific click(it's relay switching click) for that soundcard on startup.
Could this be due to a malfunctioning driver?

[skolkerom]

Code: Select all

 # apt install firmware-linux 

Done, but situation is unchanged

[Head_on_a_Stick]

Did you reboot?

Have you tried any live versions of distributions with newer kernels than Debian stable's 4.19 branch?

[skolkerom]

Yes, I did reboot, but haven't tried new kernels.

[skolkerom]

My fault, I didn't connect additional power cable.
Thanks!

So my confusion was entirely appropriate then
