Install alsa-driver, alsa-lib, alsa-oss.
Insert (adapting it) this in your .asoundrc
pcm_scope.level {
type level
}
pcm_scope_type.level {
lib /u/cvs/alsa/alsa-lib/src/pcm/scopes/.libs/liblevel.so
}
pcm.dsp0 {
type meter
slave.pcm 'hw:0,0'
scopes.0 level
}
Then try:
aplay -D dsp0 file.wav
or the more complex
aoss realplay /u/music/real/music.rm
and you'll see amazing things ;-)
