No sound

[mikedelo]

Hello all!!!


I have a new install of Ubuntu and have zero sound.

Any ideas on fixing this? I miss my youtube and CD player!


Thanks!

Usually this is due to the PCM audio setting being turned off. Open the mixer (right-click on speaker icon in task bar and select open), then slide the PCM slide to some level you can use, ditto for the Master volume slide. The keyboard shortcut keys only affect the Master control, not the PCM, so usually I set PCM to highest setting and adjust Master to where I want the volume.

PCM audio? When I right click on the speaker icon the options are mute and sound pref. I click on preferences and it looks like the sound is turned on.

but is the volume turned up? You usually have 3 levels in your mixer. Whenever I open my mixer I have Front, Digital, and PCM. Usually when you don't have sound its because the volume is turned down on on Front and/or PCM. Digital would be my headphone jack.

Everything is turned up and the speakers are on and plugged into the correct jack in the back of the computer.

Could this be a driver issue?

Possibly, but I haven't found too many systems that don't work because of that. What is your computer and audio hardware? Post the output of the command sudo /sbin/lspci here.

This is what I get

michael@michael-desktop:~$ sudo /sbin/lspci
[sudo] password for michael: 
sudo: /sbin/lspci: command not found

I don't think I am looking at the right section of settings. I don't see anything that says PCM.

then do

whereis lspci

[scathefire]

how about just

sudo lspci
