Description of Problem:
I don't know if this is an alsa or pipewire bug, but I thought I might report here first. I have a USB DAC+amp combo that has started disconnecting/cutting out since the last reboot. It just resets itself, audio switches to my speakers for a bit and when it connects again audio goes back to my headphones through the DAC. It's configured as a Digital Stereo (IEC958) output device through pavucontrol. The issue is sporadic, happening sometimes 10-15mins apart, sometimes 1min. Here's the pipewire log from journalctl:

Jun 15 01:05:18 cuprum pipewire[3070]: spa.alsa: iec958:2: close failed: No such device
How Reproducible:
Not sure if this is consistent on all up-to-date arch installations and USB IEC958, or it's something specific to my combo.
Steps to Reproduce:
- Use USB IEC958 device on archlinux
- Listen to something and wait I guess ¯\_(ツ)_/¯
