deej stop controling volume

[jffz]

Deej stops controling windows mixer when I don't use my computer for some time.
Computer does not go to sleep or screensaver mode.

OS: Win10 Pro ver. 20H2 - 19042.630
deej version: v0.9.10

Here is the attached log. Note that the 2 last lines are me stopping deej to restart it.

Hi there @jffz, thanks for writing.

Can you please describe the issue with more details? Do you have steps to consistently reproduce it, or is it a random thing? Have you tried replacing anything about the hardware configuration, such as a different board or USB cable?

I can't find anything suspicious in the attached logs, but it's possible the debug executable could tell us more.

It's best if you join the project's Discord and reach out there, because usually due to the nature of problems like this, they're more difficult to debug in a GitHub issue (we would of course update here so that people reading in the future can benefit from whatever we learn).

Updating here for anyone reading this in the future: we did some more triaging over Discord and eventually figured out that the hardware was just disconnecting from serial (which caused deej to stop working silently). The reason here was not due to the PC going to sleep, but because the monitor to which the device was connected was (which cut off power to its USB ports).

For this reason I recommend to plug deej directly into a USB port on your PC.

In the future it'll be made clearer when a disconnect has occurred and can't be automatically recovered from.
