Raspbian Wheezy Audio

Question

I've got my new Rpi running with the raspbian wheezy debian distro which is great but I can't seem to play / hear any sound.

Does anyone know if the wheezy distro comes with audio drivers pre-installed or do I need to run some manual commands to install the appropriate drivers?

I'm using the HDMI output to my TV which if I understand correctly, should send audio output as well?

Many Thanks,

Phil

Answer 1

You don't need any extra software but you do need to set the audio out to HDMI. If you are running XBMC then System -> Settings -> System -> Audio output -> Audio output HDMI will do it. You can also specify your speaker configuration and whether your TV or AV amp supports AC3 and/or DTS.

If you aren't running XBMC I'm not sure. I'll take a look.

You should check out the official Wiki's Troubleshooting section for Audio.

Especially this part:

Enter the command 'alsamixer' and use the control to check that the volume is up (arrow keys) and that the output is not muted (M key).

The modules should be loaded by default when you're using Wheezy.
