I have a dual tv card setup and everything is working well. However, the sound Im getting from one card is distorted (but really only noticible with words starting with F or ending in S). I've tried getting audio from the patch cord (tv card out->line in) and from my digital box (rca->out to line in) and both resulted in the same distortion. So now Im thinking that the problem is due to either my soundcard (from lspci C-Media Electronics Inc CM8738) or to some setting in mythtv specific for this tv card. My sound card says it records at 48K so that setting should be fine.... so Im lost. any suggestions?
