[SOLVED] PCM not showing up on Alsamixer

I'm having trouble to get audio working on Arch, I tried to unmute the audio channels but I think the problem is that when I use alsamixer, it doesn't show the PCM channel. What should I do?

Re: [SOLVED] PCM not showing up on Alsamixer

Welcome to the boards, please post more information about your audio setup. What's your output of

aplay -lL
amixer -c0 #Or whatever card index should be the card
sudo dmesg | grep -E 'snd|sof'

Thank you! I'm new to Arch and am trying to fix some kinks

Please wrap those in

[code]code tags[/code]

Your current default device is the amdgpu HDMI output. Assuming that's not really what you want, you should change your default sound card

THANK YOU, the sound is working now, the pcm channel showed up!
Btw, what do you mean by asking me to wrap the code? I don't know how to do that, if you could explain it to me so that I can use it in the future when I post another problem.

Re: [SOLVED] PCM not showing up on Alsamixer

I gave you a literal example, whenever you want to post output write a [ code ]long output here [ /code ] without the spaces at the beginning and the end of the output respectively.
