Since the last update PulseAudio keeps randomly switching streams from my analog output (which I connected my headset to for video calls) to my USB amplifier that drives my speakers (for listening to music). This used to work perfect, now I always have to keep pavucontrol open when I'm in a conference so I can quickly switch the streams back.
