Try a newer build of DSOAL. That log is showing an older one that's using EFX instead of the EAX extensions.

Muting just turns down the input gain to 0, but the device is left running. From OpenAL and ALSA's perspective, the device is still there producing samples, it's just being...

Possibly because the device doesn't have a feature to signal an unplugged input. The device is still physically present, but the wires that would transmit the analog signal aren't connected...
