Sound cuts out after one or two minutes

[mr_tin]

My apologies if this was discussed in another thread, please direct me to it.

I have just installed a TUL (ATI) Theatre 550 Pro tuner card. I have tried Powercinema, GBPVR, and even Nerovision (for recording) and I am having the same problem in all.

The sound and picture start off fine but after approximately one minute or so the sound cuts out. If I change channels, it comes back then cuts out again after a minute. I have already taken the card back to the store where I purchased it and they said it worked fine with Powercinema on one of their PCs. I have even tried it on my other computer and have the same problem. I don't like to give up but I have spent hours on this now.

I have done the reinstalling and updating drivers thing, disabled timeshift, antivirus, screensavers etc.

Does anyone have any suggestions?

Sounds like driver problems to me if its affecting all those apps. Sorry, I know thats not particularly helpful, but its likely ATI is the only ones that will be able to help you.
