Do you mean users plug their external input into the TV Capture card, which is then connected to the Line-In of the Soundcard? ie, Ext. Audio source -> TV Capture Card -> Soundcard Line In If it works when the saa7134 driver is not modprobed, then it's due to hardware initialization defaults (LINE1). On my FlyVideo 2000, I don't get audio passthrough until I explicitly select Composite/SVideo which selects the correct ext. audio inputs (thanks to GPIO bit manipulation requirements). IMHO, I feel that enabling audio passthrough when the driver is not loaded is incorrect. I may have an external source which I only want to enable when I'm running something that uses the TV capture card (e.g., recording, viewing, etc). I presume that you're using an audio only source like a hi-fi system. I'm not sure what would be a reasonable solution to this issue, though from Gerd's reply, you may want to reorder the input sequence to achieve your desired results. As for 2), I guess there's a bug (no, I haven't looked at the code yet). T.C. ---- Wan Tat Chee (Lecturer) School of Computer Science, Univ. Science Malaysia, 11800 Minden, Penang, Malaysia.
