I’ve tried really hard to pin this down without rebooting in the past, but to no avail, and now it’s happened again – sometimes, very rarely, an application will become laggy, and then I will alt+f4 out of it, but immediately after that, ALL of my audio devices will disconnect, despite all being plugged into rear I/O, 1 USB, 1 in a 3.5mm slot… but all of my other USB devices will work, the only thing that drops out are audio devices.
–I’ve tried restarting every audio service known to man, but they give bus errors (I think something along the line of “no bus medium found”)
–EasyEffects doesn’t crash. Pavucontrol and EasyEffects both work, show audio playing, but there aren’t any output devices. - EasyEffects sink is in Pavucontrol, nothing else is, not even my disabled audio devices or HDMI/DisplayPort audio device. - EasyEffects says “(none)” for all recording and output devices
okay, i restarted pipewire and pipewire-pulse, and this time, there’s not a single audio device or stream.
easyeffects sink is now missing from pavucontrol, all that’s left is ‘System Sounds’
–can i please get some help with this? rebooting my pc isn’t an option right now

these errors popped up at the same time as when i ran the wpctl status command, starting to think this is related to the tty errors from today - they showed up at the same time as the audio disappeared, but i don’t know how to “escape” the seemingly present tty shell that isn’t present because i’m still in my x11 session

they continued after i returned from leaving for an hour
That’s above my paygrade, don’t know what is going on. Something is seriously borked, and org.freedesktop.DBus.Error.NameHasNoOwner probably points into the direction that the audio subsystem isn’t the root but a symptom.
tried restarting dbus (not a good idea) to regain ownership of it, could no longer log in, rebooted pc, back to normal
it’s annoying because this is the second time this has happened and i know its going to happen again
the “solution” is to reboot. if it comes up again i’ll check it again
