Hi all, @JimH, @Matt
thank you. The windows sound settings are working as said, the testbutton in the above picture plays the sound (7.1) on all boxes/channels).
And as I said, it is from version 24 up, because I bought v33 and was wondering, why nothing came out of SR. in v.23 IT DOES.
And as mentioned, (AIMP,) HQPlayer 5 are playing all channels, so it must be in the MC.
Thank you.
