5.1 playback has stopped working

[daknuts]

Hello...

This is a weird problem that just started happening today.

I have been mixing a movie in 5.1 for over a month now and today when I opened Audition and started working, playback is only coming out in my Left + Right speakers. The meters show my mix in 5.1 as usual but what I hear has me 'flying blind' while mixing and editing.

In Audition, I have tried re-setting the audio hardware and mapping to the normal 5.1 setup I have been using all along (WASAPI) and all of the routing looks right on screen. When I test the output of the soundcard and my amplifier with the Windows sound setup test app all of the speakers show up correctly in 5.1.

I also tried re-booting the program, re-booting the PC. When I play my exported 5.1 file in VLC media player it plays correctly in 5.1.

I did not perform an update, either.

This problem is absolutely driving me insane and it 's beyond me what could possibly have happened.

Any ideas?

thnx

Danny

In further testing, I exported a section of the movie (in 5.1) and opened it as a file in the file editor which then played correctly from Audition. So confusing...

That last bit may be a clue. Multichannel playback from Waveform is set up separately from that in Multitrack, so it sounds very much as though it's a Multitrack setting that's been misplaced somehow. Assuming that the individual track assignments are still correct, which it sounds as though they are, then it might be worth checking in the Multitrack mixer that the Master track output there is set to 5.1 default, rather than stereo. I think that would cause the effect you're getting, although I have no means of checking that here, I'm afraid.

You are an audio master

Not sure why it changed as I haven't touched anything before, but I went to the master channel and opened up the dialog box for output and looked. It was set to 'default output' in the 5.1 section so I changed it to 'default' instead and it immediately appeared as 'default surround' on the input strip, which was not one of the choices, but works to give me back the surround output I need.

The look on my face reads 'wtf??'

Thank You!!!!!
