[mythtv-users] PVR350 Enabling Sound through SCART Lead

[Paul Wheeler]

Thanks for your help, after 5 hrs of playing with all the ivtv
controls I finally worked out the problem, the scart output was being
passed through a new samsung ntl cable box. It was this box that was
not passing the audio through properly, once i plugged it straight
into the tv it was fine. Bloody ntl.
