Hi,
what ALSA pcm device have you configured Audacity to use? From the log
it looks like it tries to use some pcm devices that are commonly
configured in a global alsa.conf (on ubuntu for example in
/usr/share/alsa/alsa.conf (.d). Possibly you do not have these global
definitions available?
Does using "hw:0,0" work if set as pcm device in the audacity config?
Regards,
Flo
P.S.: I'm not using guix ATM, so I have no idea on where the guix ALSA
packages would store global configs, etc..
