sample for reproduction

XAudio2 doesn't handle device disconnect well. It looks like it hangs the thread and prevents the application from exiting.

Steps to reproduce:

1. Play audio with SDL.
2. Disconnect your speakers/headphones, or disable them in the "Playback devices" panel.
4. Re-enable or reconnect the speakers.
3. Quit the SDL app.

Expected result:

The sound should resume playing when the audio device is reconnected. App should close neatly without leaving a lingering process.

What happens:

There is no sound after reconnecting the audio device (step 4), nor does it switch to another device when available. When the app quits, it seemingly closes, but a lingering process remains.

Workaround:

Use 'directmedia' audio driver on Windows.

I am attaching an example SDL app, which you can use to reproduce and test the issue.

Forgot to add: this might be related to bug 2940.

This should be fixed in revision control.

Comment 3 Ryan C. Gordon 2017-05-27 20:07:07 UTC 
Going to resolve this bug for now, since this is believed to be fixed, and XAudio2 is going away anyhow.
