In the late 90s early 00s I had a Compaq laptop which occasionally will fail |
24 |
to produce any audio output. Booting into Windows would on its own unlock the |
25 |
audio and allow me to enjoy my audio card on Linux once more, until the next |
26 |
time. |

I never bottomed out what was causing this, but I developed a theory of a |
29 |
dodgy Linux alsa driver which would trip over itself when it tried to |
30 |
initialise the audio device and an always-working-as-intended MSWindows audio |
31 |
driver. |

Anyway, isn't pulseaudio being replaced by the Pipewire framework? I |
34 |
understand Pipewire is meant to work better with BT audio and A2DP codecs, but |
35 |
I don't know how well it works on Plasma. |

|
37 |
I haven't installed pulseaudio on this PC, but pipewire seems to be running on |
38 |
a Plasma desktop: |

$ ps axf | grep -i pipe |
