Alright here is my story.

I've managed to get the tv out working on my pvr350 with the "Use the pvr-350's tv out/encoder checked by following the great instructions on this page. But I get no sound. I've followed the instructions from this thread and recompiled the drivers and checked the aumix and alsamixer settings and everything is fine.
I also entered this command test_ioctl -y mute=0 but I still don't get any sound. So if anyone can help me, I would be in your debt forever.

Thank You

you are either using the sound output from the pvr350 to your speakers/reciever, or piping the sound out from the pvr350 back into linein on the soundcard right? For testing purposes I would go directly from pvr350 sound out -> speakers/reciever.

Yes, thats correct, currently I've connected the sound outputs from pvr350 directly into the tv ans still no sound.

Just a little update.
I exchanged the card for a new one and switched the video drivers from ivtv-0.1.9a.tar.gz to the ivtv-0.1.10-pre2-ck77b.tgz drivers and boom, everything work perfectly. I just wanted to thank the people that helped me on these forums and thank cesman for this awesome distro.

I followed
these instructions to get everything working.

Thank you
