[SOLVED] UR22C unwanted reverb on headphones out (dspMixFx)

Headphones out produces reverb, sounds like REV-X is on, but it’s not (or at least dspMixFX shows it’s off). Main outs are normal (no reverb).

I’m on windows 11, latest drivers.

Any ideas? Cheers.

(UPDATE)
Connecting headphones with a TRRS connection (Audio L/R + Mic) will result in:

Left channel: Left audio only
Right Channel: Stereo audio mixed to mono

which caused the “reverb” I was hearing (left channel was also louder than the right channel, I’ve seen some people having this issue on this forum).

Anyway, this was no software/hardware issue.
Using a TRS headphone resolved it.
