I have installed two 350 cards on the lastest version of KnoppMyth, I am looking for a way to have sound controlled by the remote on both cards.
Currently the one card is using the s-video out and repointed the sound to an onboard sound card which is then output to the TV.
Any suggestions on making the second card work with sound?

I'm confused. Do you want the sound to come out of both cards? Or do you want the remote for each card to control the volume of the sound comming out from your soundcard?

Sorry should have made myself clear.
Having two cards I would like to control all features with the remote.
I am trying to figure out a way to manage the sound if I switch cards while making a recording or switching tuners
Currently i have the sound from one card running out of the s-video connector and running into the back of my SB live card from there I run it into the back of the TV. This does work although I am still unable to manage the volume from the remote.

You're aware that the PVR cards (like the 150, 250, 350 and 500 models) encode live tv including audio to an mpeg2 stream and that it is mythTV saving this stream as a NUV-File onto your harddisk, aren't you? I just don't see the sense of your cabling between the PVR 350 and your sound card. My cabling looks like that:



I have no cable plugged in from any of my PVR from/to my sound card.

Ok it makes sense now that I think about it since all live TV is buffered then it makes sense that the audio is part of that.
Wish I was home right now so I could test, been sitting on this for about five days.

That works fine for playing back the mpeg-2 streams myth recorded from a hauppauge card. But what if you want to use mplayer or xine to play a media file (.mp3, .avi, .mpeg and so on). There will be no sound from the pvr-350! The sound will come out of your soundcard though.

So to get both the hauppauge sound and the mplayer/xine sound to your one TV you can use your soundcard as a mixer. It will combine the line-in and the mplayer/xine generated sound into one signal.

If you never intend to play .mp3s, .avis or other files, then by all means just plug the pvr-350 to the TV directly. There is nothing wrong with that.

To get myth (and your remote) to control the volume of the sound change the setting for which mixer channel myth should control. It is in the setup section of the frontend. The setting you need is "master volume control" I think.
