hd pvr low volume audio and buzzing

[profit]

I isolated the source of a low volume and buzzing issue to my hd pvr. I have an hdhr that works fine as well as media streamed from my Vista Ultimate x64 server to my hd200.

I have attached two screen shots that show various settings. It might be obvious to some of you Sage pro's and I'm hoping you can help. I connect the hd200 to the TV via hdmi.

I noticed on the last recording with the hd pvr, under recording detail it displayed:

[H.264 1080i AC3| 384Kbps @ 48 khz stereo....

Any idea how to eliminate the buzzing and correct the audio for the hd pvr?

---------> Issue solved - With Time Warner Cable I had ordered an HD cable box to use with the HD PVR. By default this box was set to use the box to control the audio rather than my TV. Under settings on TW Cable box I changed the audio output from variable to fixed. That let my TV control the sound rather than the box. The low audio and buzzing are now gone.I

I too have the audio variations between HD channels and non-HD channels (for both the HD-PVR as well as the 2250 card). Can you tell me which TW cable box you have? I have the DCT 6200 model and can't see where any audio settings would/could be set.

I have an HD Pace Box. On my remote I click on Settings and scroll to the right immediately via cable remote and click on Audio. I still have the buzzing on some channels. Never any buzzing when listening to music and the audio volume is much higher.

I thought I had it fixed. It might be a bad cable box. Anyone have any other ideas?
