Moving to ports, not an engine specific issue.

Raising all identified crasher, hang, and memory violation bugs which I could not fully triage myself to blocker priority for the next release.

I can reproduce it on Windows 10 17025 by unplugging my USB sound device.

Backtrace attached, but not really helpful without debugging symbols in SDL2.

Please download and use a DLL from the Development Libraries archives at to get debug symbols.

comment:9 by rootfather, 3 years ago

Strange... I cannot reproduce this issue on the current master codebase on Win 10 17046... Neither forcing a bluetooth device to disconnect (by unplugging the power cable of my bluetooth speaker) nor unplugging a USB sound device leads to a crash. Instead, ScummVM automatically switches to the next audio device.

rootfather: which SDL version where you using to testing the audio devie disconnection crash?

SDL 2.0.6 release notes says "The new default audio driver on Windows is WASAPI and supports hot-plugging devices and changing the default audio device". So it is possible that the crash would be fixed when using SDL 2.0.6 or 2.0.7.

comment:11 by rootfather, 3 years ago

I'm using SDL 2.0.7. Good to know that this seems to be fixed by upstream.

Owner: set to criezy
Resolution: outdated
Status: newclosed

Considering the ticket was created well before SDL 2.0.7 was released, it was obvious it was using an older version. I will assume that the issue has been fixed upstream in SDL. Feel free to reopen if you can reproduce with a recent SDL version.
