So after having Dish moved from my old house to my new house, I have a new issue. I'm using the same 622 and aiwa DD receiver that I had previously used with no issues.
Here's the issue. My 622 is set to DD/PCM mode. Start on HIST HD channel, turn aiwa on and I get DD stereo display and output thru the front speakers and center speaker (I can hear the voices). If I change the channel to HIST SD channel, the aiwa displays ProLogic and I hear all audio. I change back to HIST HD and I get the DD stereo display but now no audio thru front speakers, only from the subwoofer. I turn the aiwa off and back on and the audio works fine. I can repeat above to reproduce the problem.
So because of this, anytime I switch around thru channels, I sometimes get missing audio with some channels.
Now, geez, I'm here watching Jay Leno and 622 in DD/PCM mode. The aiwa displays DD5.1, but I hear nothing but sub. It goes to commercial and it works fine, full DD5.1. The next commercial, nothing but sub, next commercial, fine. WTF??
So frustrating.
