Powered subwoofer wails and whistles. Center speaker produces static only. Have 5 bose speakers plus the Subwoofer.
Have tried several connection setups, generally favoring an optical connection between the Dish HD DVR 622 STB and the Onkyo
TX-DS595.
Surround sound does not appear to work at all. Stereo, direct, all channel stereo all work ok on 4 speakers, center speaker is static only.
I need a way to test the Onkyo to verify the surround sound function. Assuming it fails, I also need a repair facility.
The surround processing portion of the unit has a problem. In either stereo or direct mode, the digital procesing is bypassed. This could be just the surround processing IC, but that IC may not be available as a separate part. I would suggest that you bring this unit to an authorized Onkyo service center for an estimate.
