I can repro "no sound" on Allo BOSS 2.
I suspect this is due to some sort of incompatibility between the custom Allo driver for the Boss 2 and the new 6.1.y Linux kernel branch. This would require Allo to troubleshoot but AFAIK their softwares are no longer being maintained.
Options:
1. Stay on moOde releases <= 8.3.0 which do not use 6.1.y kernels
2. Try downgrading to 5.15.84 kernel on moOde 8.3.1 using the commands below (untested). While this might work to resolve the specific Boss 2 issue it creates an 8.3.1 configuration that can't be officially supported and may have other breakage.
I did a spot check on some other DAC's with custom drivers for example Allo Katana and Audiophonics ES9038 DAC and no issues under the 6.1.y kernel. Same for other DAC's like Allo BOSS, IQaudIO DACZero, ProtoDAC TDA1387 X8 and Allo Revolution DAC (USB).
