Here is the output of amixer. Does it look like something is going wrong here ?
-bash-3.1# amixer set PCM 80% Simple mixer control 'PCM',0 Capabilities: pvolume Playback channels: Front Left - Front Right Limits: Playback 0 - 31 Mono: Front Left: Playback 25 [81%] Front Right: Playback 25 [81%] Running speaker-test also doesn't produce a sound.

No, but two utilities that can help debugging are amixer and speaker-test. amixer is deprecated for configuring the card, but you can use it to dump out the current setttings in a visually unambiguous way. speaker-test is just nice for testing sound because you don't have to keep a file around. It will just give you some tones to listen for. I would start by looking at the output of `amixer' so that you're confident the controls are setup correctly. More than one user (including me) has failed to setup the device correctly through `alsamixer'. I plan to put this info into the book at some time. -- Dan -- http://linuxfromscratch.org/mailman/listinfo/blfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page -- http://linuxfromscratch.org/mailman/listinfo/blfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
