There are well known problems with USB audio on the PI - please search this thread or other threads on that. Some people report 16 bit dacs are ok, others are not. However the problem is likely to be the PI not squeezelite - so please try alternative hardware if you can. ------------------------------------------------------------------------ Triode's Profile: http://forums.slimdevices.com/member.php?userid=17 View this thread: http://forums.slimdevices.com/showthread.php?t=97046 _______________________________________________ unix mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/unix
