Hi Marin,
Yeah there are a few work rounds.
Mix is the easier work around, IMHO.
The Mix GUI allows individual channel gain control for all USB interface channels.
Ideally the procedural parametric EQ faders need to be fixed.
One would expect a year would be ample time.
I personally feel ARC has taken the Lion share of DEV attention and focus.
I just wish the functional faults users report and Roon ticket were actually actioned.
For instance, another fault reported in May 21, which still appears to be an issue.
