VLC has Problems with Multichannel Output

[mruebsam]

Hi,
vlc just plays the stereo tracks when I try to playback a surround sound movie. I get an error message (like I have to configure my device in the audio/midi setup) as soon as I switch to the surround tracks. It doesn't matter if this is a dts, ac3 or multichannel arc track. Other programs like logic, MainStage have no problems with Jack or with the direct communication to my audio interface card (Setting up the loudspeaker tab in audio midi, certainly changes nothing..)

I have following configuration:
Mac Mini Server i7, 8 GB
Mac OS 10.9
VLC 2.1.2
Jack Pilot 0.9 beta 17
FireWire 12 Output / 10 Input Audio interface Prism Orpheus

Can anybody help me?
Thanx, Marcus

nobody?

Does it work with Jack disabled? Did you try a recent nightly build from http://nightlies.videolan.org ?

Hi,
tried already the latest beta...
There is no difference if I use jackos or if I go directly into the Prism Orpheus.
vlc says: I have to configure my device in Audio/Midi... and just uses the Stereo Tracks...

Hi, I just tested some more. VLC connects perfectly to to the multi channel fire audio...
But as soon as I put jackOS in between, vlc just plays the stereo channels
Any ideas?
Thanks, Marcus

My problem is similar : i experience a regression
My last VLC version was 2.0.2 version and the multichannel sound was Ok when i configured "use SPDIF if possible" on the Audio section.
Now this checkbox has desappeard in VLC 2.1.2 (that i downloaded for security issues i have read).
Result is that multichannel sound is now stereo or "multichannel blinking" (maybe related to this topic : https://forum.videolan.org/viewtopic.ph ... TS#p394804) on my Yamaha receiver.. except if i downgrade to my old 2.0.2 VLC version.

No. The SPDIF checkbox is still there, you might need to take a closer look.
