[linux-audio-user] ALSA mixer issues - update

Update:

I rebuilt ALSA to 1.09b and rebooted.  

I now have mixer 'sliders' in alsamixer for master and PCM, however.
Neither slider actually has any impact on the sound lever in my speakers.

Muting the PCM channel actually stops the sound.  Muting the MASTER channel has
no effect at all.

I am testing with mpd (music player daemon) set to output as follows:

o_driver         "alsa09"
ao_driver_options "dev=hw:0,0;buf_size=4096"


I have also tested with XMMS and the Alsa Plugin v1.2.10 [libALSA.so]
with the same results.

Any hints / clues would be appreciated.

aloha,
dave
