Just to be sure, 'capture' means 'recording' in ALSA speak ;-) > With a CD in the drive, and the CD player indicating that it is > there and playing a track, and with the mixer (either alsamixer or > Kmix) showing CD selected and volume high (80%+), there is still no > sound out.

And 'master' (and 'pcm' for digital audio sources) should also be unmuted and a have a reasonable volume level. > #chkconfig --list sound > sound 0:off 1:off 2:on 3:on 4:on 5:on 6:off > #chkconfig --list alsa > alsa 0:off 1:off 2:on 3:on 4:on 5:on 6:off > #runlevel > N 5 OK, so alsa and sound are started in runlevel 5: graphical environment plus network. > Any takers? :-) > > Hopefully... > Dex What happens when you try 'aplay <some_wave_file>' ?
