Phantom center channel support for Mac OS X

[Durandal]

Right now, I have a Klipsch Promedia 4.1 speaker set. It's great the VLC supports multi-channel output directly through the analog ports without the need for pass-through, but VLC only supports 5.1 output. It cannot detect the presence of a 4.1 speaker set and mix the center channel down into the two front channels. As a result, my channels get screwy. Using the AC3Test.vob, my channels come out like this.

Code: Select all

AC3 channel Output channel ----------------------------------------- Front Left Front Left Front Right Front Right Center Rear Left LFE LFE Rear Left No output Rear Right No output N/A Rear Right

Ideally, the center should be sent to the two front speakers along with the two front channels in a 4.1 setup.

Whoops. I forgot to mention that I'm using an M-Audio Revolution 7.1 with the 1.2.9 drivers.

Find me a CoreAudio developer

I would love to fix this, but currently we lack the knowledge to fix these problems. Apple just doesn't provide enough support for developers on this particular subject to get this working properly.

[Durandal]

That sucks. Hard. I'd heard that CoreAudio development was a bear. Have you tried contacting Apple about this issue?

[Durandal]

Would it be possible, then, to just have an option to decode the AC3 to 2 channels and play them through both the front and back pairs of speakers?

I get that same output with 5.1 channel speakers with the revolution 7.1

And yeah, with no support for the analog out from apple dvd player, vlc was the only other option, too bad.

So I'm not the only one who's having problems. I've already reported this: viewtopic.php?t=1684

But I'm using 5.1 and the channels are wrong too. How can we solve this problem? Contacting Apple? Beg the VLC team to work on a fix?
