Multiple sound renderers

[carpeVideo]

This is an odd one - but what would be nice is the ability to have a secondary sound filter and renderer that is used during playback.

I'll just give an example of my set up to explain why.

Nvidia motherboard with on-board sound which is two devices: 1. realtek HD audio, 2. Nvidia HDMI HD Audio

I have the HDMI attached to a plasma display and the realtek attached to a receiver via SPDIF.

Since GBPVR only outputs to one audio device at a time when I watch movies in surround I want the receiver and use Nvidia audio decoder -> Realtek SPDIF to get pass through surround.

During regular TV or non-surround I switch to the HDMI via any other audio decoder.

Needless to say its a bit painful and when family/wives/girlfriends are using the application nearly impossible.

So every time I want to watch movie in full surround I have to go through the config app and change the setting. I grabbed a last graph and added an infinite tee to the sound and rendered both and voila - true passthrough surround via the SPDIF and regular PC audio through the HDMI. So the wish is a setting (probably just in the config.xml) where a secondary audio decoder and secondary renderer can be specified for use via a tee filter during playback.

I suspect this type of set up is going to become more prevalent with all the new mboards with HDMI out so it will become useful to many more users than just myself.

Cheers,

why not just use spdif for everything?
very possible and no quality loss..
plus, how would gbpvr know when to use either? i guess you could always use both..
but i bet that would lead to crashes on some material..

Because it requires turning on the receiver and adjusting the receivers volume instead of GBPVRs volume control.

With the tee - both are always on so GBPVR doesn't need to know - you get surround if you power up the receiver. Not sure about crashes but it should be fine since the each get the same stream copied.

Tell me more about this tee thing - I'd love regular sound from the PC and/or bluetooth headphones...

The way I conquered this is as follows:

1) Use AC3Filter to handle your audio

2) Use analog out to the plasma

3) use SPDIF to the receiver

4) set AC3Filter to passthrough AC3 and DTS via SPDIF

5) leave everything else in AC3 alone (well, tweak it to your liking, etc)


This way I get analog volume control from within PVRX2 for everything BUT surround sources. To hear anything with AC3 or DTS at all, though, you'll have to turn on the receiver. I actually have it looped back out of my TV through the optical connection, so I use the receiver for all sound and just turn off the TV speakers, but you don't have to. It wont play sound to the TV during surround playback. Just don't play the receiver without turning off the speakers or you'll get horrible delay echo (if your plasma has speakers at all...if not it's a moot point).

It should work. I'm sing the realtek HD audio as well. Just make sure you enable the digital out in their app thingy otherwise you'll bang your head against the wall trying to figure out why it wont work.:confused:
