Rotel 1068 - sound problem when switching from DD to PCM feed

[mickster1972]

Hi:

I was watching an off-air HD broadcast in HD and dolby digital, with my 1068 working fine, except when the broadcast switched to commercials. Since the commercials weren't mixed in DD, the 1068 took the PCM feed and switched over to Dolby PLIIx (which is my default for TV viewing), but the sound cuts out for some reason. When the broadcast swithced back to the HD show in DD sound, everything was fine again. Has anyone else experienced this? Is is a 1068 software issue? Thanks.

Yup, software issue that has been fixed. Hold down mute and let me know what version pops up on the display just to be sure.

This is off topic, sort of, but might be related.

If I'm watching TV (rca inputs), and say, switch to my DVD input (optical) and start playing a movie, if I switch inputs back to TV, my 1068 will stay on the optical feed from the DVD player.

Does that sound familiar?

The unit will always default to analog if it cannot find a digital signal, it sounds like you have two inputs assigned to the same digital signal. When the DVD is off, the TV input defaults to analog. When you turn on the DVD player, a digital signal is now present and the TV input will no longer default to the analog. (It plays the digital signal).

You would need to choose the TV input, go into the setup menu, go to the INPUT menu, go down to the INPUT option, and then change that to ANALOG.

Ahh, that is likely it! Thanks Kevin!

Thanks, Kevin. It is version 1.1.9. Should I upgrade the software?

[Kevin D]

Yup, here's the list of changes you would get:

V1.1.9 to V1.2.1 - Fixed an intermittent problem of units locking into “Standby” mode until the rear panel power toggle was engaged. - Improved digital input sensing and format detection. This improvement fixes any problems with no audio when changing channels with some Scientific Atlanta HD digital cable boxes.

V1.2.1 to V1.2.2 - Corrected an error which caused very low center channel output when switching between DD/PLII to PLII modes.

You should be able to get the update file and instructions at the Rotel website, and you can search here for some more help if needed.

Automatic muting of commercials? That's not a problem, that's a feature!
