alsa-project/alsa-python issue #11 was edited from HEnquist:

I'm running the [hctltest2.py](https://github.com/alsa-project/alsa-python/blob/master/test/hctltest2.py) test.

Then change one of the controls, I tried the "Z Test Volume" that gets numid 4: `amixer -D hw:0 cset numid=4 5`

This generates and event, which runs the callback function. That results in the test script crashing, with:

``` Fatal Python error: drop_gil: drop_gil: GIL is not locked Python runtime state: initialized

Extension modules: pyalsa.alsahcontrol (total: 1) Aborted (core dumped) ```

Tested on manjaro with python 3.11, and latest alsa-python.

Also tested on Python 3.8.19, using the latest alsa-python code directly from this repo, with the same result.
