Deleting the registry keys fixed the issue. I will update this if I run into the issue again.

Looks really odd :thinking: No wonder from such of glitches are appear on Windows oftenly with each update.

I think I found out the problem, it's when I'm changing the output device to something that can be removed (like a Bluetooth device for example)

I see, then, it's probably a case of RTAudio that won't be dropped into another device automatically. With a case of PulseAudio on Linux that happens easily: the current audio output gets to be dropped into another output device if the current gets being suddenly removed :thinking:

@sneakernets , try 64bit build of OPL3-BE I made recently, it should work.

[sneakernets]

Alright, I will check this this weekend. thank you!

[sneakernets]

This has been fixed as far as I can tell. sorry for the long delay on this!

[sneakernets]

I may have spoken too soon. Same issue is happening again with Bluetooth headphones. Here are the current Reg values that are causing the crash:

[sneakernets]

I mean, I can "fix" this by nuking the registry every time but man that's a bummer. I wonder if this is a QT bug?

[Wohlstand]

I guess it's a crash because the RtAudio library fails to use a non-existing audio device. I should add the check for audio device availability until to start its usage.

[Wohlstand]

The question: does that happen during the workflow? Or just in a moment when you try to restart the program after you unplugged the device?

[sneakernets]

it's happening when I try to start to program after I unplugged.

[Wohlstand]

Okay, the fact a thing does work on Windows 8.1 fine when I unplug my USB headphones and do plug them back, and the application does still work when I unplug my USB-headphones while the program working. I'll try to bypass the device through my USB filter into my Windows 10 VM and see the result...

It's a high change that the crash is an exception thrown by RTAudio. The best idea is to put try-catch around audioOut->openStream and extract the message.

Closed because of no response for a long time.
