It should pass thru. (Famous last words). I think we have just solved the 48k restriction on HDMI that has been around for a while. I find ALSA documentation quite difficult to follow. Have a look for "A close look at ALSA". I found this article helpful. The ALSA setting 80:4:: doesn't affect rate as far as I know. There should be no need to manually edit the pCP config file. If it's in the config file, it is accessible/editable from the web interface somewhere. Have you thought about connecting the Opus DAC directly to the Raspberry Pi via i2s? regards Greg ------------------------------------------------------------------------ Greg Erskine's Profile: http://forums.slimdevices.com/member.php?userid=7403 View this thread: http://forums.slimdevices.com/showthread.php?t=97803 _______________________________________________ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix
