Encode all system sound to pass over SPDIF

[GoogleCodeExporter]

This requires an virtual sound card driver to implement.
Project that may be used as the starting point:

This would be a PERFECT feature for this filter, at the moment only kxDriver 
(that
doesn't work with an x-fi) and creative Dolby Digital Live! encoder can do that

That would be awesome. At the moment, the only software that does that is the
kxDriver mentioned by giulio, and has a very limited sound card support. If 
AC3Filter
could encode all analog system sounds to 5.1, it would be very useful for 
gaming, as
most of them support 5.1 channels, but only in the 6 analog discrete channels. 
I'm
sure a LOT of people would enjoy that.

I use DTS Connect on a SoundMax AD1998 chip for the same purpose, but it 
crashes 
with lot of games.

A better solution would be AWESOME.

Would be a killer feature. No need to buy expensive sound card with DTS connect 
or DD 
Live.For now im stuck with 3 cables running all over my room,Would be nice to 
change 
them for single optic SPDIF cable.

5.1 in games through spdif would be awesome!

Please, it would be very useful, expecially with 5.1 audio games

This would be the one of the best features added in history of mankind.

Indeed, this would truly rock. I believe the Pulseaudio sound server can be set 
up
like this on GNU/Linux environments?

Seems like this can definitely be done...DDLive is actually implemented by the 
CPU after all.

+1  Also, they need to fix the AC3 Filter description which says "It can encode 
any audio source to AC3 on-the-fly and send it over SPDIF to the receiver. "  

It cannot encode 6 channel PCM to AC3 (gaming, etc.).  It's not clear what they 
mean by "any".  I'm looking into getting Dolby Digital Live or DTS Connect 
working but I'll have to buy a new sound card.

I'm guessing this hasn't been done yet because of licensing issues but I hope 
I'm wrong.

I would love this!! This would be the best (and only) solution to iMac or 
laptop owners to experience 5.1 games :D
Please make high priority ^_^

This feature would make PC gaming and AC3Filter so much better. It's what we've 
been needing for ten years! If Dolby Digital Live and DTS Connect can do it, 
AC3Filter can as well.

Here's a working virtual driver solution:
http://ac3filter.net/forum/index.php?topic=93189.msg96074#msg96074

This needs to be streamlined, the bugs worked out, and latency reduced by 
tweaking sampling if necessary.

I'm trying to figure this one out as well. I've seen people have succeeded with 
VAC (like comment above) but I'm looking for a free solution.

It *should* be possible with JackAudio (instead of VAC) although I couldn't get 
it to work.

I'm going to try writing a DirectShow usermode only virtual audio card, or 
maybe modifying AC3Filter to behave as an audio renderer filter (although I'm 
not entirely sure this is possible yet)

Here is another related thread:

0Type%20Status%20Stars%20Priority%20Milestone%20Owner%20Summary

i also wish for this option to pass all audio through the ac3filter before 
output through sound card.
I get the impression that windows at least needs a audio driver to pass audio 
through, as everyone has been talking about here and it seems that implementing 
this driver is complicated but, based on how far ac3filter has come i can see 
this becoming possible since most audio decoded through most codecs become pcm 
before being sent to the sound card except any pass-though media such as DD, 
DTS, and WMA pro when being sent through spdif.

virtual audio card solution

Breakaway Live - for the virtual card driver (just use the demo version)

AudioResampler (a product from the same company must be run to make the driver 
work instead of outputting white noise, no need to start anything in 
AudioResampler just minimize it)

of course set it all up in graph studio 
http://blog.monogram.sk/janos/tools/monogram-graphstudio/ but my problem as i 
have made a link to in my last post is that there is a noticeable delay and has 
become worse when using the more recent graph studio next
