No Sound Fresh Install

carlosinfl · 11-17-2011, 12:14 PM

I've just installed Debian Linux (Wheezy) and I hooked up my speakers and don't hear any audio from flash or sites that commonly stream sound. I know I would need 'alsa' so I manually installed 'alsa-base' but that did nothing. How can I properly troubleshoot my system and verify I have the correct packages for sound to properly render on my new Debian Linux machine?

I did verify my login user is a member of the 'audio' & 'cdrom' group.

Code:

carlos@tuna:~$ groups
users cdrom audio

Try to run

Code:

alsamixer

to see if nothing is muted.

Kind regards

No problems in 'alsamixer'. It comes up just fine. When I press 'M', I can see it mute the channel with 'MM' at the bottom. Anything else?

Do you have;

in your sources.list? You probably need it, depends on what you want to listen to.

Do you have the package "firmware-linux" installed? It is in the non-free section. It is a meta package that pulls in firmware-linux-free and firmware-linux-nonfree. That last needs to be installed for sure. Many of these are included in the kernel but removed by Debian as they do not meet the Debian standard for "free".
