Hello,
I have the same problem (CQ 12 T). It happened to me with two different computers: iMac 2023 and MacBook Pro 2018, both with updated operating system (Sonoma 14.3.1) (the two computers obviously have different processors). And it happens to me both with Logic Pro and with Audition and with any other sound source (Qobuz, Youtube, etc.). All parameters are configured as written in the Guide (Sample Rate, etc.). When this happens, the software I’m using crashes. Similarly, it blocks the QC from turning off if I use the Shut Down button (it stops the image that usually spins). The firmware version is 1.1.1 (r3684). I’ve noticed that the problem mostly pops up when I change the listening mode: if I switch back to using CQ after switching to the internal speakers or WiFi speakers, I don’t hear any sound. I have to turn the mixer off and on again to get it working again. I wrote emails to support.
