Sorry for the vague description. My W/ works pretty consistenly - so when something goes wrong I haven’t often been paying complete attention to the preceding problems.
The audio was also a very brief piece - so it’s sounds like it could also be the SD driver. I didn’t use the clear queue commands before it happened - if that helps to pinpoint anything
The module still doesn’t respond when I reboot normally - would you recommend re-installing the firmware? I could also try re-booting into Izzy.
