I did experience the issue with an FIIO headphone DAC too. Basically, when connecting the device, the balance slider in audio settings would get initialized to what seemed to be a random value. I am using several other audio interfaces (both USB and Thunderbolt) as well for music production/recording and I have never seen that issue with any of those devices. I suppose it is an interoperability problem between the USB audio class driver and core audio that only manifests for certain types of devices. Still, if it is common enough for people publishing apps to fix it, Apple should get it sorted out.
This actually vaguely rings the bell. I think it happened just a few times and because I quickly heard it I corrected the slider and did not pay attention at the time I suppose.
Don’t think it ever happened in DAW though, only when playing audio from OS.
