Today I have no DD audio with channels 802 (CBCHE) and 804 (CBCHW) with Bell. Channel 209 (CBCHDE) with Shaw also has no DD audio. The past few days I have noticed that the news between the Olympics has no DD audio but the Olympics did. Every other channel works fine with DD audio. Have others noticed this as well?

Dolby Digital is being received at CBC Toronto via ExpressVu now, 10:45PM Sunday.

I've noticed that the CBC HD channel is much quieter then the NBC HD channel while showing the Olympics. Does anyone know why this is?

I find it quite annoying that you have to crank up the volume on one channel just so you can hear it a bit better.

Side Note:
I've also noticed that in my Big Brother episodes that are on my PVR it's also very quite.
Has anyone else noticed these things? You'd think all HD would be DD, but even then I find that the audio is lackluster.

All digital channels are DD, however, not all are DD5.1. Those that are DD5.1 are often quieter than DD2.0 programmes. The inequality of digital channel volume has been discussed often on this forum and unfortunately, there's not much to be done at this stage (unless you have a TV or AVR that has some volume equalization capability, which may impact the sound quality...).

I discovered, much to my chagrin, that my Rotel receiver was missing the L and R front speakers. The center and surround speakers and sub are still working. When CBC goes to a commercial or half hour news during the Olympics, they switch over to 2 channel stereo sound. The day I posted this thread, they must have been broadcasting the Olympics in 2 channel DD. Most of the sound comes out of the center channel with 5.1 so it is easy to not notice that the L and R front speakers weren't working. Now to find out what happened to my Rotel.:o

When the L & R speakers aren't working, it's usually because someone has turned them off. There's often a speaker switch for the A and B set of speakers and if you turn the A speakers off, then you don't hear anything out the LF & RF. Check that speaker switch... If you have children in the home, they often like to press the speaker A button causing this issue.

That's a helluva lot different than not getting DD5.1 though... ;)

My Rotel has no A or B speakers, only A, and I have no kids (I am the big kid!). I have checked every possible menu and remote setting to no avail. I recently replaced the backup capacitor but I am pretty sure that all the speakers were working when I put it back together (although with DD 5.1 I only notice the L and R fronts when I stand right in front of them). That was a month ago, and just in the last week it has been coming on by itself--maybe indicating that something else has gone wrong in the meantime. Hopefully it is just a board that came loose when I took it apart.

Luckily my TV actually has volume equilization capability, so that really help the sound quality on my digital cable.

I had replaced the backup capacitor about 4 weeks ago and must have inadvertently (partially) disconnected one of the plugs going from the display board to the power supply. The plug was hidden down below another circuit board. That would also explain why it was coming on by itself from standby. And here I was hoping it was time for a new receiver with HDMI and lossless decoding!
