CQ18T Headphone A and B only left ear?

Very strange thing here. I have Aux 1 and 2 linked stereo

I have Headphone A and B sources mapped to my Aux 1/Aux 2 stereo link

When I plug a stereo cable into my headphone amp I’m only hearing things in left ear. If I pan, for example, piano hard right it disappears…sometimes can FAINTLY hear it from Heasphone Out A. Nothing from B

If I plug a pair of headphones directly into headphone jack A (taking headphone amp out of the equation) I still have same result

It USED to work fine. Any idea what I’m missing here? I’ve factory reset same results

If I plug a mono a/b to stereo directly into Aux 1 and Aux 2 works fine

Really like headphone jacks though for reasons not worth getting into

Any tips for debugging?

Thanks

Oddly enough I switched the source on the headphone to MainLR and it worked fine

I then switched my source back to my stereo link aux 1 and 2 and everything started working

Sometimes you just have to shrug and move on. No idea what happened but it works again

The problem occurs for me particularly during the playback of multitrack recordings. Although a played-back channel is panned to the center, I only hear the signal on the left side. Interestingly, the right channel is not completely dead. When I pan to the right, I hear (only) the right channel of the stereo effect, but not the source signal, which should also be audible. So, the right channel is not defective. That’s why I assume it’s a software bug. This is further supported by the fact that it usually works again after turning the system off and on.

Edit: I did some further testing: when the right side drops out and I pan all the way to the left, I can still hear the source signal very faintly in the background. Contrary to what I said earlier, it’s not the right channel of the stereo effect. It is the source signal, but extremely weak.

Something strange just happened: while I was listening to one channel of a multitrack recording through headphones, the right side of the headphones suddenly cut out but then gradually came back. The right side was completely gone for about 5 seconds, and then over the next 5 seconds it slowly returned to its original volume. After that, both sides were fully working again.

Yes this is exactly what balanced to me

Hasn’t happened again but it’s most definitely a software issue

In the end, it turned out to be a hardware defect after all. I had the mixer repaired under warranty free of charge, and it was done within two days. (Thanks for that.) The mainboard had to be replaced.
