Notice the sudden sound increase when I go down to 149%

When I set my headphone's volume to 150%, then disconnect it, then connect it again, the audio is presumably at 100% until I reduce the volume to 149%, even though the UI shows "150%".
Comment 1 David Edmundson 2024-10-13 14:51:50 UTC 
Can you attach output of:
'pactl list sinks' both at the broken 150% and correct 140%.
Comment 2 David Edmundson 2024-10-13 14:53:34 UTC 
Also for the sake of another discussion (https://invent.kde.org/plasma/plasma-pa/-/merge_requests/282) can you write a bit about why you run it above 100%?
Comment 3 Fernando M. Muniz 2024-10-13 15:10:07 UTC 
BROKEN 150%:

I run above 100% when the sound of the thing I'm hearing is low, or I'm in other room, or outside.
Comment 5 Fernando M. Muniz 2024-10-13 15:50:48 UTC 
In any case, the volume percentage being displayed contradicts the actual volume, therefore it's a bug.
Since 101%+ is going to be removed or hidden, it makes more sense to just make the text say "100%" when the reconnected device had 101+ volume before being disconnected.
Comment 6 Harald Sitter 2024-10-14 01:56:27 UTC 
Does pavucontrol show the volume as 100% or 150% after you reconnect?
Comment 7 Fernando M. Muniz 2024-10-14 06:46:20 UTC 
Created attachment 174792 [details]
pavucontrol while glitched 150%

1- Set the speakers to 150%.
2- Connected the headset.
3- Disconnected the headset.
4- Screenshotted pavucontrol while the speakers were under this false 150% volume.
5- Watched a song and reduced the volume to 149% to hear a significant increase in volume.
Comment 8 Harald Sitter 2024-10-14 11:22:59 UTC 
If pavucontrol is also bugged I rather think this is an upstream bug in pipewire. As we can see in the pactl output it really thinks the volume is 150%.
