The "Output setting" is really just passing the card name and dev number to an ALSA plugin in the ALSA configuration.
If the "Output setting" is blank, ALSA will use a default config, probably the hw: plugin, with CARD=0 and DEV=0. In your case, if your USB DAC is sitting on CARD 0 it might just work (or output to Headphones?). I think the hw plugin connects to the hardware with little ALSA processing. I also think the number of ALSA options is defined by the manufacturers driver. ------------------------------------------------------------------------ Greg Erskine's Profile: http://forums.slimdevices.com/member.php?userid=7403 View this thread: http://forums.slimdevices.com/showthread.php?t=114828 _______________________________________________ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix
