Applications don't recognise USB device if it's reinserted

I'm not sure if there is a solution to this but when I start a program without my USB headset connected then it doesn't show up, obviously, but when plugging it it still doesn't show up.

Is this an application level problem or can it be solved elsewhere?

Install and use pulseaudio and pavucontrol (and pulseaudio-alsa and throw away any ALSA config you might have made before that, as pulse handles things differently). For ALSA devices to be detected and discovered a restart of the application is necessary.

I'm using Pulseaudio as-is, pavucontrool is my sound managing UI - I can't remove alsa-lib as it has so many dependencies.

Re: Applications don't recognise USB device if it's reinserted

I'm not talking about removing alsa-libs but alsa configs (e.g. ~/.asoundrc or ~/asound.conf). If you do use pulseaudio, you'll have to elaborate on what your actual problem is. What single applications think should be irrelevant as you can define where each application plays to within pulseaudio/pavucontrol. Which applications show that behaviour, what do you expect to see? What are the outputs of

sudo fuser -v /dev/snd/*
dmesg | grep usb
uname -a
pacman -Q linux
pacmd list-sinks
pacmd list-sink-inputs

while the issue occurs.
