well i figured this out finally but i still dont understand the relationship between mpd, pulseaudio and alsa. I know mpd is the network daemon that can be used to control my music collection from a compatible client (ampache), and it LOOKS LIKE it plays to pulseaudio which is a plugin for alsa(??). but anyways... finally got this working, i had to install more pulseaudio supporting packages (device chooser) and it started working .. however...
Im getting choppy audio when using the usb dac. crackly etc... read through the pulse/asla docs and they suggest changing bitrate to 48000 if thats the issue. i also tried increasing audio buffers to no avail. I can have pulse use the normal soundcard out that i run through the same dac and it sounds fantastic , so im really hoping i can figure this out as going straight digital to the amp (
nuforce icon) will be fantastic!
thanks!
