Hello Peter
I had my rounds with what I think is the same card, and let me tell you that in the end I gave up and bought another card.
Anyway, I do remember that the driver's author say the sound is still in progress.
Also, I don't know why, I could get sound in tvtime IF I chose mono and did some magic with the alsa controls, muting some channels that I would think they should be unmuted.
I never got the card to work well with mythtv, sorry about that.
Sorry that I can't help much more.
Juan

Subject: [mythtv-users] WinTV Go sound issues...Hi all,
I'm setting up MythTV 0.16 on a friend's box. It has a recent WinTV Go card with a Conexant chip so I'm using the cx8800 kernel module.
After fiddling a bit with the hue and color settings I got video playback and recording just fine. I wish I could say the same about audio...
This card has a audio line-out. For use in MythTV this line-out is connected to the line-in of the onboard sound card.
I'm also using tvtime to test the drivers. When using tvtime I connect the line-out of the WinTV Go card directly to the amplifier of my sound system.I've tried both the cx8800 v4l driver with kernel 2.6.9 and the snapshot from http://dl.bytesex.org/cvs-snapshots/video4linux-20041217-141849.tar.g z.
Here are my experiences:
- tvtime (non-buffered playback) works perfect with both the 2.6.9 drivers and latest snapshot V4L drivers. Line-out of the WinTV Go card is connected directly to my sound system.
- mythtv with kernel 2.6.9 V4L drivers: I can't get any sound out of this. I can change channels, playback and record video, but without audio.
- mythtv with V4L snapshot drivers:The same as with kernel 2.6.9 drivers, except that with these drivers a radio device is now also detected while loading the drivers. When I'm doing TV playback on mythtv (without sound), and I do a 'cat /dev/v4l/radio0', the tuned frequency of the card changes, mythtv playback switches to static, and i _do_ get static out of the speakers all of a sudden. Note that in this case the line-out of the WinTV Go card is connected to the line-in of the sound card. When I now change the channel in mythtv, I get normal tv playback _with_ audio. Video and audio are perfectly in sync. I can change channels and audio keeps on working. If I now press the 'r' key on the keyboard to record the live stream audio get's turned off again. I'm watching the tv stream without sound. Also if I exit live playback and play back the recording stream from the media library, I see that no sound is being recorded. If I do 'cat /dev/v4l/radio0' again, I can watch live (buffered) TV again with sound.
There is no radio device detected with the kernel 2.6.9 cx8800 V4L driver so I can't try this with those drivers
As you can see in the dmesg output below, with the snapshot drivers a radio device is created and not with the kernel 2.6.9 drivers.Also, the snapshot drivers detect a MSP3425 audio processor but the msp3400.ko module is not needed for audio to work.
Since unbuffered TV playback in tvtime is working fine and via 'cat /dev/v4l/radio0' I can get sound output on the WinTV Go card enabled in MythTV, I suppose the problem lies in MythTV itself.
Has anybody seen this before? Is this card maybe not yet supported in MythTV? Or maybe the CVS version of MythTV has some fixes for this?
Thanks & kind regards,
Peter
