Rpi4 No Sound

Postby mach98 » Thu May 20, 2021 12:31 pm

I have followed all the other posts, I could find through some searching.

Installed alsa-utils, tried to change to Analogue output (there are only 2 HDMI outputs)

I have run $this->bbcode_second_pass_code('', 'amixer -q cset numid=3 1')
and receive the following error:
$this->bbcode_second_pass_code('', 'amixer: Control default element write error: Operation not permitted')

I receive that error whether I use the command as sudo or not.

Any idea what might be causing this?

Hello

Hard to tell without seeing your config.txt but maybe the solution of solskogen can help if your using kms :
