Allright, I'll give you some details:
First of all, here is my .asoundrc file :
# start .asoundrc
pcm.dsp0 {
type plug
slave.pcm "dmix"
}
ctl.mixer0 {
type hw
card 0
}
# end .asoundrc
As you can see, only the pcm volume is controlled with dmix (I couldn't
find how to use dmix for the main volume), so I have to control the PCM
channel with amixer to set the volume properly.
That's when I modified ossmixer.py so that it uses amixer instead. To
enable alsamixer.py, first copy it to
/usr/lib/python2.4/site-packages/freevo/plugins (or something like that,
you can find / -name ossmixer.py to find this folder)
Then, you have to setup freevo to use it, so edit your
~/.freevo/local_conf.py and add/change the following lines:
# Enable alsamixer
plugin.remove('mixer')
plugin.remove('ossmixer')
plugin.activate('alsamixer')
# Tell mplayer to use alsa (do it for xine too if you use it)
MPLAYER_AO_DEV = 'alsa'
# Remember that we have to control the PCM channel (if you control the
master channel, there's no need for this line)
MAJOR_AUDIO_CTRL='PCM'
I think that's about it ...
Tell me if it works for you ;)
