Description of problem: Unplugging a webcam (046d:085c Logitech, Inc. C922 Pro Stream Webcam) causes the "/usr/bin/pipewire-media-session -d bluez5" process to go into a hot loop trying to read from the sound control associated with the camera (the camera has a microphone): strace: ``` [...] read(19, 0x7ffd068ca9d0, 72) = -1 ENODEV (No such device) epoll_wait(3, [{EPOLLERR|EPOLLNVAL, {u32=2591091504, u64=94169749056304}}], 32, -1) = 1 read(19, 0x7ffd068ca9d0, 72) = -1 ENODEV (No such device) epoll_wait(3, [{EPOLLERR|EPOLLNVAL, {u32=2591091504, u64=94169749056304}}], 32, -1) = 1 read(19, 0x7ffd068ca9d0, 72) = -1 ENODEV (No such device) epoll_wait(3, [{EPOLLERR|EPOLLNVAL, {u32=2591091504, u64=94169749056304}}], 32, -1) = 1 read(19, 0x7ffd068ca9d0, 72) = -1 ENODEV (No such device) epoll_wait(3, [{EPOLLERR|EPOLLNVAL, {u32=2591091504, u64=94169749056304}}], 32, -1) = 1 read(19, 0x7ffd068ca9d0, 72) = -1 ENODEV (No such device) epoll_wait(3, [{EPOLLERR|EPOLLNVAL, {u32=2591091504, u64=94169749056304}}], 32, -1) = 1 read(19, 0x7ffd068ca9d0, 72) = -1 ENODEV (No such device) epoll_wait(3, [{EPOLLERR|EPOLLNVAL, {u32=2591091504, u64=94169749056304}}], 32, -1) = 1 [...] ``` lsof: ``` [...] pipewire- 17308 sun 17u unix 0x00000000e80db616 0t0 383573 type=STREAM pipewire- 17308 sun 18u unix 0x00000000368e9d3c 0t0 383574 type=STREAM pipewire- 17308 sun 19u CHR 116,13 0t0 299728 /dev/snd/controlC1 (deleted) pipewire- 17308 sun 20u unix 0x00000000c8abce84 0t0 383566 type=STREAM pipewire- 17308 sun 21u unix 0x00000000c8abce84 0t0 383566 type=STREAM [...] ``` both /usr/bin/pipewire and /usr/bin/pipewire-media-session need to be killed to recover.
