Lev, Ralf, thanks for your efforts to try to help here, much appreciated! Nice idea to make a connection with jack from a hardware input to the S/PDIF directly with a rythm and test it. I've set the mixer to the corresponding hardware input. I do see the meters going up and down and i do have the sync signal on my amp. But no sound. Even when the hardware playback is NOT connected, i have the analog sound on the digital mixer output. Can this indicate this an internal routing bug? And: Because the S/PDIF output works in Windows XP, i suspect that there is a software bug somewhere, perhaps alsa?? -- View this message in context: http://linux-audio.4202.n7.nabble.com/Delta1010-S-PDIF-out-has-sync-but-no-audio-tp92201p92425.html Sent from the linux-audio-user mailing list archive at Nabble.com. _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
