Description Marcos Kintschner 2018-06-13 20:38:23 UTC 
When wasapi is stopped (state set to NULL) and removed from pipeline, the program crashes. I've pretty much followed this example https://gstreamer.freedesktop.org/documentation/application-development/advanced/pipeline-manipulation.html#dynamically-changing-the-pipeline (but used only wasapisrc, audioconvert and wasapisink).

The error shown on log is the following:

:00:07.985599364  5144   042788A0 INFO              wasapisink gstwasapisink.c:680:gst_wasapi_sink_reset:<autoaudiosink0-actual-sink-wasapi> reset called
0:00:07.985654852  5144   042788A0 ERROR             wasapisink gstwasapisink.c:687:gst_wasapi_sink_reset:<autoaudiosink0-actual-sink-wasapi> IAudioClient::Stop failed (1): Incorrect function.

I get this exact error, except instead of crashing my program freezes when I try to start playback again.

I'm curious if the patches from https://bugzilla.gnome.org/show_bug.cgi?id=796354 would fix this, but I don't currently have an appropriate build environment set up at the moment.
Comment 2 Dustin Spicuzza 2018-06-24 23:26:37 UTC 
Actually, I think this is fixed in https://bugzilla.gnome.org/show_bug.cgi?id=796280
Comment 3 Dustin Spicuzza 2018-06-25 00:12:18 UTC 
Hm. So I decided to set up a build environment (Windows 7, msys2, 32-bit) and built the current 1.14 branch (479b1ef76) and copied the wasapi dll over my current environment's dll.

The sound from that build is terribly garbled and sounds weird -- and of course, didn't fix the crash either.

I am on a VM. However, the current 1.14.1 release in msys2 plays music that isn't garbled, so I suspect that isn't the issue.
