Bug#1013756: solfege: crash with pyalsa

[Michael Below]

Package: solfege
Version: 3.23.4-11
Severity: normal
X-Debbugs-Cc: be...@judiz.de

Dear Maintainer,

when I tried solfege for the first time it used OSS MIDI through the
sound card. There was a message in the config window that ALSA couldn't
be used because pyalsa was missing. I installed python3-pyalsa from
testing, and the next time I opened the config dialog in solfege it
crashed. I expected it to offer ALSA MIDI instead.

Cheers
Michael

Hello Michael!

Thanks for reporting this issue. This is a problem in python-alsa
itself that have been reported in [1], fixed upstream [2], but the
Debian package is still waiting for an update.

I reopen associated bugs and try to update python-alsa.

Best Regards,
François

Hi, I had the same bug, so I try to follow the instructions given in

https://github.com/alsa-project/alsa-python/commit/a64a6cc703d08db5c223a16bf812a569534ba464

I could "hear" some improvements (some sound), but now I am face to
