Multichannel VAIO and VLC

[output]

I recently encounterered VB Matrix and it seems to be able solve all my audio related concurrency problems.
I installed and configured it, but unfortunately ran into some issue

I use a PC (Windows 11) with only one physical audio interface (Arturia Audiofuse 16RIG)

For video editing and playback I use 5.0 audio, will use a VAIO device in Windows for playback.
Initially during setup I mapped only the front speakers to VIAO channel 1 and 2

When selecting the 2ch virtual device in Windows everything works.

But when selecting a virtual device with more than 2 channels:

• Windows soundtest works

• Audio from browser works

• VLC remains silent (does work when Windows is configured for 2ch device)

I assume that for some reason VLC does not open the multichannel device.

Any solution/workaround for this ?

Thanks in advance,
Marcel
