Hi, I'm back again. I upgraded to Ubuntu 8.04 which uses PA as the default sound server and new hardware(AMD Athlon X2) The PA server is version 0.9.10. My /etc/default.pa looks like this: .nofail load-sample-lazy pulse-hotplug /usr/share/sounds/startup3.wav .fail load-module module-alsa-sink sink_name=intel_hda_out device=hw:0 load-module module-alsa-source source_name=intel_hda_in device=hw:0 load-module module-alsa-sink sink_name=delta_out device=hw:1 channels=10 channel_map=left,right,aux0,aux1,aux2,aux3,aux4,aux5,aux6,aux7 load-module module-alsa-source source_name=delta_in device=hw:1 channels=12 channel_map=left,right,aux0,aux1,aux2,aux3,aux4,aux5,aux6,aux7,aux8,aux9 set-default-sink delta_out set-default-source delta_in .ifexists module-esound-protocol-unix.so load-module module-esound-protocol-unix .endif load-module module-native-protocol-unix load-module module-volume-restore load-module module-default-device-restore load-module module-rescue-streams load-module module-suspend-on-idle .ifexists module-gconf.so .nofail load-module module-gconf .fail .endif .ifexists module-x11-publish.so .nofail load-module module-x11-publish .fail .endif To get feedback from the PA server I used paman (pulseaudio sound manager in ubuntu) and it said that the intel_hda_out device is the default sink. I tried to force the default sink to be delta_out with pacmd, but that stopped the PA server... I didn't realize that when I exit paman, it shuts the pa server down. I was a little confused by that... expecting the server to stay alive. I noticed that I could "play-sample" to the delta_out and it sounded fine. It looked like I can get my Delta 66 card and PA to work but only in that "play-sample" mode. I did not realize that I had the volume-restore enabled, and it had quite a few settings from the past that were all related to intel_hda_out... also my ~/.pulse/default-sink file was also set to intel_hda_out... anyway even though the global config file(/etc/pulse/default.pa) set the default sink to delta_out, there are local config files in ~/.pulse/ that can also modify the defaults. It's probably in the literature somewhere, and it makes sense for clients that are sharing a server. Anyway, I after changing *all* (local and global) the config files, the system works... and pretty well. Hope this helps someone with their M-Audio Delta setup.
