I have been fighting with this for quite awhile now - and have posted previously about this as well. But I am still getting nowhere.
I have a Pinnacle PCTV Pro capture card, that has a Conexant chip. V4L registers the video device, but no audio device.
I can run tvtime and xawtv, and get (analog) video, but no audio. This is with both the coax tv tuner input and the S-Video input. When I try to run VLC I get the error main input error: demux doesn't like DEMUX_GET_TIME
I have read that this chip sends the captured analog audio via DMA, but I don't know if the V4L driver handles that.
I have tried various utilities (alsamixer, arecord/aplay, paman) to try to make this work, or at least find out what is happening, but still no luck - just a lot of confusion.
PLEASE! Anyone with any knowledge (or pointers to knowledge) of this PLEASE help.
