When Audacity starts, it prints this line: ------ ALSA lib conf.c:3683:(snd_config_hooks_call) Cannot open shared library libasound_module_conf_pulse.so (/gnu/store/nyylgcnzmbw8wrn4sna2crl0g7zxxh33-alsa-lib-1.2.2/lib/alsa-lib/libasound_module_conf_pulse.so: libasound_module_conf_pulse.so: cannot open shared object file: No such file or directory) ------
