Works in serial monitor but stopped working in windows
Hi,
2 weeks ago my deej just stopped working in Windows. CH340 driver did not change, still using 3.5.2019.1. Serial monitor still shows changes when moving the sliders, it's just that the windows application does nothing and doesn't show anything useful in the logs:

Same issue,
but for me it came after I had a bluescreen on the CH340 driver of my arduino nano. Windows 11 then installed a newer driver version from wcn.cn (the legit manufacturer of the CH340). After that, audio control stopped working. DeeJ still connects. Arduino serial monitor shows some weird signs in the first few frations of a second before putting out the normal stuff (maybe it was like this before, never checked). Found something in the logs, but no clue how to fix it:

I noticed, that the highlighted line is not appearing anymore in current log files, only in the old ones. Sometimes, if I reset my arduino upon deej starting just in the right time, it will print out this line, but only detecting 1 slider (everything is set up for 5 sliders)
FINAL EDIT: In issue 130 there is the same issue reportet. They mention something about the "Fake CH340G" driver and a fix. URL: https://github.com/SHWotever/FakeCH340DriverFixer
Tried it, first try failed to install the fake driver, second try worked. After that, audio control was restored
A quick note for other Windows 11 users: The "fixed driver" and Windows 11 do not go along very well with each other anymore. I had an update end of April, now I'm on: 24H2 build 26100.3775. This version does not like the fixed driver anymore and throws BSODs, sometimes after a few seconds after boot, sometimes after hours. Always a BSOD regarding the CH340G/CH341G (don't know why it's showing it like this).
Plugged the control panel that gifts me BSODs into my Windows 10 computer, now working for 24h with no issues at all.
