Subject: Audacity does not work with PulseAudio
Date: Fri, 24 Apr 2020 17:37:27 -0400

Since I can remember, Guix's Audacity doesn't work with PulseAudio on my
foreign distro (Debian).

Debian's Audacity does work correctly in this regard.

In practice, this means that I cannot play or record audio in Audacity
while any other application is using sound on the system. If I close or
stop those other applications, then Audacity is able to select the
'sysdefault' output sound device and can start working.

I found a few discussions about similar issues [0], and it seems that
Audacity needs alsa-plugins in order to make this work.

I tried installing Audacity along side alsa-plugins,
alsa-plugins:pulseaudio, and pulseaudio, as well as building with them
as dependencies, but it still didn't work.

I'm very happy to report that this fix has been deployed for Guix users
in commit ed1c72c3d7d6b6d3b110817fcc037cd5582ac848
