The DVB stream that is transfered over PCI includes both video and audio, no need for cabling when DVB is in question. > 2. What is the pin assignment for the SB connector?

If it has the ability to record DVB to .nuv files as well, they contain audio as well. > Any clues or pointers gratefully received - I'm getting good at lip > reading :) I'd guess MythTV frontend audio settings are not configured properly. -- Anssi Hannula _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
