AVR3312CI surround sound encoding modes worked correctly since installation and now suddenly do not. For example with any of the DOLBY modes the audio is distorted and you cannot hear voices. Audio fine in multi-channel stereo mode. Resetting the Microprocessor and manual set-up does not correct the problem. ROKU and Apple TV2, both with separate HDMI connections have this problem. Is there a solution to this problem, or is the AVR3312CI defective?

Don't quite get what the problem is. Between installation and "now suddenly' was anything changed in your setup?

No changes, worked fine one day, not the next. Have installed the upgrades to the AVR via the WEB as they come, but the problem did not occur immediately after an upgrade.

Occasionally I've been experiencing the same problem with my 2310CI, but it usually works fine after a re-boot. Maybe blowing some compressed air might correct the problem?

Further research provided enlightenment! Dolby 5.1 (7.1) uses the center speaker for voice. Found that one of the center speaker wire terminals was dead. Changed center speaker and all OK, have both the sound track and voice. Thank you for the suggestions.smile.gif
