AudioDSP not working with USB Soundcard

Hi Guys!
I have a problem with the AudioDSP Addon.
I am using a 5.1 USB SoundCard
Got it working with the builtin Alsa, if i activate DSP processing, everything is fine, too.
I now would like to adjust the channels, especially give the center speaker more volume but when i active that module in the DSP-Addon i do not hear anything in movies, it is like audio is muted.

Any hints on what i am doing wrong ?

I don’t think AudioDSP actually works in Jarvis

Well that would be a bummer :frowning:
