--- Comment #5 from J.O. Aho <tr...@iname.com> ---
I have a similar experience, but not during login (this tend to work for me
quite fine)
Plasma: 6.1.4
KDE Framework: 24.05.2
Pipewire: 1.2.2
Kernel: 6.10.3 (arch)
nVidia: 555.58.02
Audio device: Starship/Matisse HD Audio Controller (pro audio selected in
pipewire)

Have two X11 sessions (User1 and User2, login with User1 first, then switch
user from kde menu and login with User2), switch between them in one of two
ways:
1. Use "Switch User" from the KDE start menu
2. Use the ctrl-alt-fX key combination


Effect for me:
The volume icon in the panel is "crossed out", everything is laggish and sudden
freezes from time to time until the volume icon is back to normal. This
normally takes up to a minute, sometimes it's take just a few seconds, which
makes me think it's an timed even than handles something instead of listening
to an event. For me this didn't happen until pipewire 1.2.1 and Plasma 6.1.3
(got those at the same time).

(when the previous row is written, everything is back to normal)

when using strace on plasmashell I get a lot of following:
read(4, "\2\0\0\0\0\0\0\0", 8)          = 8
write(4, "\1\0\0\0\0\0\0\0", 8)         = 8
write(4, "\1\0\0\0\0\0\0\0", 8)         = 8
poll([{fd=4, events=POLLIN}, {fd=27, events=POLLIN}, {fd=29, events=POLLIN},
{fd=30, events=POLLIN}, {fd=32, events=POLLIN}, {fd=59, events=POLLIN}, {fd=60,
events=POLLIN}, {fd=61, events=POLLPRI}, {fd=62, events=POLLIN}, {fd=63,
events=POLLIN}, {fd=69, events=POLLIN}, {fd=70, events=POLLIN}], 12, 4) = 2
([{fd=4, revents=POLLIN}, {fd=59, revents=POLLIN}])

Not sure if this is related to Philippe's issue or not, but feels quite
similar.
