Sample rate issues with M-Audio M-Track 2x2M
alsa-project/alsa-lib issue #176 was opened from powerjungle:
At random points the sample rate changes, but the applications continue to use the previous rate. This results in sound being lower/higher pitch then normal. My own voice when using the application [Mumble](https://github.com/mumble-voip/mumble) consistently becomes higher pitch and sounds pretty funny, friends had a good laugh. I have some diffs of ALSA dumps.
My output is to headphones. My input is XLR.
Here for example I open the GNOME settings for "Sound" and my output becomes lower pitch:

```
Afterwards at a random point the output gets fixed, but the sample rate that gets logged is weird:
