It would be better if it explained that this is a _video_ codec, but Gentoo's USE flag and package descriptions have always been rubbish.

A little bit OT, but does anyone know how to satisfy Firefox's need for audio device. If I have no asound.conf Firefox will use hw0,0 for audio output. If I set asound to:

pcm.!default {
 type hw
 card 0
 device 0
}

ctl.!default {
 type control
 card 0
 device 0
}

Sorry. Wrote this from memory so there might be a typo somewhere. With these settings Firefox don't playback anything... Other applications and flash plugin works perfectly.

How could I get firefox to use hw0,3 or hw1,3 for HTML5 audio playback?
