Hi, since S/PDIF is consumer class people are used to connect S/PDIF devices and I assume everything will work without the need to care about something else. S/PDIF usually isn't used for audio production, this might explain why people tend to forget to set up the clock source. AFAIK there's no need to care about it, when using stand alone consumer devices. I suspect that sync very often is the culprit, when S/PDIF used with prosumer or pro-audio devices doesn't work. Since I'm not using S/PDIF I ask somebody using it, to write a Linux audio Wiki that mentions to set up the master clock manually. 2 Cents, Ralf _______________________________________________ Linux-audio-user mailing list Linux-audio-user@xxxxxxxxxxxxxxxxxxxx http://lists.linuxaudio.org/listinfo/linux-audio-user
