Iām still having issues with data on my SD card getting corrupted (resulting in audible glitches) all the time. Iāve already tried several SD cards but no luck so far. But since there are obiously lots of folks around here that are using w/, this doesnāt seem to be an issue with the module in general. Apart from that, I never experienced any issues with the module.
I think Iāve read somewhere around here about an upcoming firmware update, but Iām not sure and donāt have any details about that. But Iām really hope that it will maybe solve these issues, so I can finally use this awesome module without unwanted noises, cracks and glichtes 
Also, Iām still hoping that the firmware will one day become open source - at least thereās already this Github repo, but itās still emptyā¦
