Package: libportaudio2
Version: 19.6.0-1
Followup-For: Bug #944509
X-Debbugs-Cc: tg at mirbsd.de

I’m getting a crash in libportaudio2 at polyphone startup if JACK
is not running (polyphone ought to be happy enough with just ALSA):

After reading this bugreport, it might be this issue.
If there’s no reaction within the week and the patch
fixes my crashes, I’m intending to NMU.
