[pulseaudio-discuss] config for 2 cards - 1 for pulse; 1 for AC-3 Passthru

Hi All,

     I've been trying to figure out for some time how to configure my 
family home theater PC for analog pulse audio out and ALSA digital pass 
thru for Xine.  I'm running Ubuntu 10.04.

     I've been having some success by removing the pulse library from 
xine.  The issue is that sometimes "something" happens to the digital 
port and I no longer get digital sound.  The workaround has been to 
switch the audio output to a second unused but present sound card and 
reboot.  After one or two repeats toggling the sound output between 
cards I can again have digital sound through one port and analog through 
another on the same sound card.

      I had another thought which would be to blacklist my Soundblaster 
card (which supports the digital passthru) from Pulse and have the 
analog from Pulse through the onboard sound.

     Any thoughts on how to fix my initial problem or configure the 
second scenario?
