I have taken your advice and am now using plughw:CARD=ALSA,DEV=0. Everything is coming out the headphone jack as expected. I tried various files from 44KHz to 384KHz, and various radio stations. SB3 -> Quad 909 -> Quad Electrostatic speakers, Quad 405 -> TBI subwoofer 3 x SB3s + SB Radio Rotel RSP1068 surround processor, Quad 99 -> B&W surround ------------------------------------------------------------------------ rbl's Profile: http://forums.slimdevices.com/member.php?userid=4517 View this thread: http://forums.slimdevices.com/showthread.php?t=112025 _______________________________________________ unix mailing list [email protected] http://lists.slimdevices.com/mailman/listinfo/unix
