Audacity doesn't work with pulseaudio anymore

**UPDATE:** Today's upgrade to alsa-lib-1.1.7-2 fixed the issue. (2018-11-23) ---------- Arch Linux, up-to-date. As so often, a -Syu upgrade broke things again. This time it's audacity. Usually audacity, and **any** other playback/record app would show up in pauvcontrol - Not audacity anymore. I could use pauvcontrol to choose sink and source from which I want to record or playback audio using audacity - not anymore. In audacity's preferences it only says ALSA in the top dropdown, im not sure if that is supposed to be like that or if it said PulseAudio before. There aren't even all my devices in the playback tab. Same goes for the recording device selection, but the loopback device I need to record from is there, so that works. But now I wanted to playback sound from audacity too and it just doesn't work anymore. It doesn't list my USB playback device and when I set it to sysdefault I just get an error. $ pulseaudio -v pulseaudio 12.2 $ audacity --version lilv_world_add_plugin(): warning: Duplicate plugin lilv_world_add_plugin(): warning: ... found in file:///usr/lib/lv2/eg-params.lv2/ lilv_world_add_plugin(): warning: ... and file:///usr/lib64/lv2/eg-params.lv2/ (ignored) lilv_world_add_plugin(): warning: Duplicate plugin lilv_world_add_plugin(): warning: ... found in file:///usr/lib/lv2/eg-midigate.lv2/ lilv_world_add_plugin(): warning: ... and file:///usr/lib64/lv2/eg-midigate.lv2/ (ignored) lilv_world_add_plugin(): warning: Duplicate plugin lilv_world_add_plugin(): warning: ... found in file:///usr/lib/lv2/eg-fifths.lv2/ lilv_world_add_plugin(): warning: ... and file:///usr/lib64/lv2/eg-fifths.lv2/ (ignored) lilv_world_add_plugin(): warning: Duplicate plugin lilv_world_add_plugin(): warning: ... found in file:///usr/lib/lv2/eg-metro.lv2/ lilv_world_add_plugin(): warning: ... and file:///usr/lib64/lv2/eg-metro.lv2/ (ignored) lilv_world_add_plugin(): warning: Duplicate plugin lilv_world_add_plugin(): warning: ... found in file:///usr/lib/lv2/eg-amp.lv2/ lilv_world_add_plugin(): warning: ... and file:///usr/lib64/lv2/eg-amp.lv2/ (ignored) lilv_world_add_plugin(): warning: Duplicate plugin lilv_world_add_plugin(): warning: ... found in file:///usr/lib/lv2/eg-sampler.lv2/ lilv_world_add_plugin(): warning: ... and file:///usr/lib64/lv2/eg-sampler.lv2/ (ignored) lilv_world_add_plugin(): warning: Duplicate plugin lilv_world_add_plugin(): warning: ... found in file:///usr/lib/lv2/eg-scope.lv2/ lilv_world_add_plugin(): warning: ... and file:///usr/lib64/lv2/eg-scope.lv2/ (ignored) lilv_world_add_plugin(): warning: Duplicate plugin lilv_world_add_plugin(): warning: ... found in file:///usr/lib/lv2/eg-scope.lv2/ lilv_world_add_plugin(): warning: ... and file:///usr/lib64/lv2/eg-scope.lv2/ (ignored) lilv_world_add_plugin(): warning: Reloading plugin lilv_world_add_plugin(): warning: Reloading plugin lilv_world_add_plugin(): warning: Reloading plugin lilv_world_add_plugin(): warning: Reloading plugin lilv_world_add_plugin(): warning: Reloading plugin lilv_world_add_plugin(): warning: Reloading plugin lilv_world_add_plugin(): warning: Reloading plugin lilv_world_add_plugin(): warning: Reloading plugin Not sure if those warnings mean anything, it won't print the version.
