Hi,
I have a VU+ Duo 2 and have been been having issues with the sound when playing back movies... The sound is clear and everything is fine when someone is speaking but as soon as there is any action or significant background music, the sound goes lower and speech is less audible - the sound levels go up and down all of the time and it is difficult to watch anything and hear it all.

I have checked for auto-levelling settings and stuff like that and all are set to off, AAC and AC3 is set to passthrough... but the problem persists.

Has anyone else had similar issues and know of a solution?

thanks.

Sounds like stuff that was recorded in a cinema with a camcorder. Are you using an amp?

Hi,
do you use an AVR for sound? If yes check the audio settings there because they often have features like auto dynamic, auto volume .

definitely not a screenscrape... - no amp and the problem is the same whether I play the sound directly through the TV or via the soundbar.

nope - just the tv and VU+ (and also the same issue if I play via the TV sound bar.
I've check TV settings for things like virtual surround, sound boost, auto-leveling etc. and all settings are correct

Hi,
a lot devices cannot decode ACC and AC3 almost makes no sense for TV and soundbar. Did you try downmix?

If you do not use downmix ALWAYS set the volume on the ATB to 90-100% as the box cannot change volume for ACC/AC3 and you would get a huge volume difference when switching between MPEG2 and AC§ sound.

Would this be stuff recorded on sat or other sources.

Might you have tried another hdmi cable.

Sometimes i need to up volume button on tv to hear more as box is on max with some recordings.

It's a Samsung tv with soundbar and sub woofer... I've tried downmix too...

But to be clear it isn't a sound difference that is the problem. It is the fact that when watching some movies there will be a scene where there is dialogue and it is perfectly clear and audible but as soon as the scene changes to action or has background music, any dialogue gets drowned out.

We just watched a programme on freeview Sat and had exactly the same issue... so it's not just recorded/downloaded movies.

It's happening with freeview sat channels via the Vu+ box and also with downloaded movies

Freeview has AAC sound which is problematic on a lot of enigma2 receivers especially multichannel audio. A lot of movie downloads use it too. Leave the stb volume at 100% and use the tv volume instead.

Freeview = terrestrial (and uses AAC sound)
Freesat = satellite (uses MP2 or AC3 sound)

Which is it?

Hi,
is it possible that your system is quite new? From what I read I think you are experiencing the dynamic of surround sound for the first time. In contrast to my 1st post I think you need dynamic compression because it limits the difference between the volume levels. On a real AVR you have also the possibility to increase the volume of the center by X dB to make conversation easier to understand. For AC3 these dynamic compression level are written in the standards and the sound track can include up to 3 different mixes. In the beginning it was called night mode because you could watch a movie without disturbing the neighbors.

What you experience is more or less realistic. Example you are standing at a street and 2-3 yards away 2 people are talking to each other. Now you can easily understand it. If there is traffic you cannot understand it anymore. And it is even worse if you have an action film with shooting, car crashes or explosions.
