Anyone else noticing the audio feed on TV2 appears to be pooze at present.

I'm getting surrounds doing most the work, and not remaining the subtle toned down outputs they usually are. It's as if the muxing is set to all channel mono output.

Changes slightly when the feed goes to a non surround advert etc, notice slight change in audio volume

Speaking of volume.. is it my receiver or is the volume difference on Four + Choice(a popular hangout) a whole lot worse than the big players which appear aligned now. Find myself needing to go from leaving receiver on about 25-27 to 34 to get the same perceived output.

Choice I can sort of understand, in some cases due to some of the older import programs. But Four is pretty bad.

To an extent.

I did a program refresh, to add the new CTV signal (which is still broken on anything but samsung tvs.. sound but no video)

It never created duplicates of any of the other saved ones as if they have been shifted.

But given it still goes, I suspect its an underlaying issue with the broadcast more than a frequency hop. As far as the decoder knows its still getting a DD signal.

And now someone has reported issues with the Kordia broadcast too.. something is afoot

Back to the original problem with tv2 and level differences between 1,2,3 and 4 or choice. Have you tried comparing the AAC audio levels between all of the channels- Dolby decoding level might be the cause of the difference in levels on your receiver?

For me 1,2,3 and 4 levels are almost identical on my Panasonic tv.

don't mess with me.... i'm the hd insider....

Listened to the surround on tv2 and you are right, the up mixing that is being done to fake the surround sound is making voice come out on all of the channels. That's gotta be a fault.

You just saved yourself from me explaining ignore the levels.. no issue and say I'll wait for someone else in chch with 5.1 to confirm :)

Noticing the centre channel is low, and the surrounds are very high.

Put the receiver into Theatre dimensional and you lose surround effects and only get slight centre and fronts. So the signalling is way off somewhere.

When it changes between adverts and program (MKR atm) you get it normal for half a second before it transitions back to the same state again.

Short while after I use their contact page using the dropdown for digital tv and point it out. It appears fixed.

Or The mentalist which I switched over to is 5.1 so its processing properly.

Maybe not.

Was still rubbish when not the actual program (or 5.1 stream). Stereo upmix fail

I have noticed the same sort of issue at home.

Running MySky HDI through HDMI to the TV, then optical to the yamaha amp. Sounds like the "Hall" sound setting has been set on the amp (slightly echo'y)

All other channels are fine, and playing with the settings on the amp does little to change it (Amp is running 5.1 surround with standard "not altered" sound mode)

Watching MKR last night, it sounded really bad!
