System Doesn't detect USB headset after suspend/resume

Sometimes (this seems to happen randomly), after a resume from suspend my USB headset is no longer detected in gnome. It doesn't show up in the sound settings output tab, and unplugging/replugging the headset does nothing. It does seem to show right up if I run pulseaudio -k to restart pulseaudio. It doesn't seem to matter if I suspended with the headset plugged in or not.

Has anyone else run into this issue, any workarounds or fixes?

Re: System Doesn't detect USB headset after suspend/resume

Sounds like an issue with pulseaudio, especially if it won't recognize the headset until you restart the service.

- Do you experience the same issue if you use another audio input or output device (USB speakers, microphone, etc)?

- Did you recently update pulseaudio?  Did you experience this problem before you upgraded pulseaudio?

- Have you tried using alsa for you audio management instead of pulseaudio?

Re: System Doesn't detect USB headset after suspend/resume

Let me quote archwiki here:

Standby / Suspend to RAM

In the ideal case, running sudo pm-suspend should initiate suspend to memory, meaning that all running state will be preserved in RAM and all components other than RAM will be shut down to conserve power. Pressing the power button should initiate a resume from this state.

In some cases, it is possible that running pm-suspend causes hangs or other issues. This may be due to specific "misbehaving" modules. If you know which modules could cause such issues, adding a SUSPEND_MODULES config to /etc/pm/config.d/modules of the form

SUSPEND_MODULES="uhci_hd button ehci_hd"

should cause these modules to be specifically unloaded before suspend and reloaded after resume.

To configure invoking pm-suspend automatically on power events like laptop lid close, please refer to Acpid.

and exactly those 2 modules you should add in the same way.. because those are responsible for usb... helped for me...
