The comment for "use PVR350 audio" checkbox seem to imply otherwise: it says that the common way to route audio is to your regular audio card, but if you really want to use PVR350 for both audio and video, check this box. > > The common way to set this up is to use a Y-cable to connect the 350 > audio outs to the line-in of the soundcard.

I don't get any sound because I did not connect PVR350 audio outs, at the very least (it may be muted too, but it seems irrelevant so far). I don't really want to add another digital-analog-digital conversion to my sound (in the end, it would have to come out of Audigy SPDIF) > > Nick > -- Fedor G Pikus ([EMAIL PROTECTED]) http://www.pikus.net http://wild-light.com _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
