After some fiddling with settings it seems I solved the clicks problem, thanks you all who participated! Tested since a couple of days with PCM up to 192 and DSD64 (DoP) and haven't noticed any problems so far. So here are my setting to run TEAC UD-501 via USB from PI3B, might be useful for somebody with same PI/DAC combo: Output setting hw:CARD=UD501,DEV=0 ALSA setting 160:4::1: Buffer size settings 20000:60000 Device supports DSD/DoP 250 250ms PCM to DSD delay was crucial to get correct click-free DSD playback. Without this setting DAC surprisingly still plays, but indicates the signal as PCM 352.8 and there are dropouts/clicks, with the delay indication is DSD 2.8mhz ------------------------------------------------------------------------ BiBer3's Profile: http://forums.slimdevices.com/member.php?userid=71556 View this thread: http://forums.slimdevices.com/showthread.php?t=111787 _______________________________________________ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix
