Bug description

after using the GUI "Sound Settings" -> "Test Sound" -> "Front Left" (or Right) the audio output does not work. This is with a USB DAC. This bug occurred only after the upgrade to Mint 22.

audio hardware is Fii0 E10 USB DAC -

i.e. sudo inxi -Axxx shows:

Device-3: GYROCOM C&C Fiio E10 driver: hid-generic,snd-usb-audio,usbhid
type: USB rev: 1.1 speed: 12 Mb/s lanes: 1 bus-ID: 1-5:7 chip-ID: 1852:7022
class-ID: 0102

Steps to reproduce

with pipewire in a clean status (e.g. systemctl --user restart pipewire) audio plays just fine (e.g. a youtube video). in this clean status systemctl --user status pipewire shows no errors

However after using the GUI "Sound Settings" -> "Test Sound" -> "Front Left" (or Right) the audio output does not work. In this broken status systemctl --user status pipewire shows:

pw.node: (alsa_output.usb-FiiO_DigiHug_USB_Audio-01.analog-stereo-49) suspended -> error (Start error: No space left on device)

Expected behavior

"Test Sound" should not rain death down upon the audio subsystem.

Additional information

thank you for your work on this wonderful distribution.

Reproduce the failure from Sound Settings �� Test Sound �� Front Left or Right after restarting the user PipeWire service, then inspect the Cinnamon sound-settings entry point and the reported USB DAC behavior. Use the clean and broken systemctl --user status pipewire outputs to compare results; done means testing a channel no longer leaves the audio node in a Start error state.
