Hello, in random way during audio/video playback there is a buzz. It seems like a latency problem but I can't be sure.

Here the problem:

I tried to update to last drivers, disable some sarvices (as I have seen in some posts), reinstall windows, but with no results. The buzzing randomly happens.

Can it be a hardware or software problem?

Other 9710 users with the same problem?

Thank you very much. Andrea
