In the late 90s early 00s I had a Compaq laptop which occasionally will fail to produce any audio output. Booting into Windows would on its own unlock the audio and allow me to enjoy my audio card on Linux once more, until the next time. I never bottomed out what was causing this, but I developed a theory of a dodgy Linux alsa driver which would trip over itself when it tried to initialise the audio device and an always-working-as-intended MSWindows audio driver. Anyway, isn't pulseaudio being replaced by the Pipewire framework? I understand Pipewire is meant to work better with BT audio and A2DP codecs, but I don't know how well it works on Plasma. I haven't installed pulseaudio on this PC, but pipewire seems to be running on a Plasma desktop: $ ps axf | grep -i pipe 4274 tty8 Sl+ 0:00 | \_ /usr/bin/pipewire 4275 tty8 Sl+ 0:00 | \_ /usr/bin/pipewire -c pipewire-pulse.conf 15917 pts/1 S+ 0:00 \_ grep -E --colour=auto --color=auto -i pipe
