[Bug 547193] [NEW] ALSA levels drop everytime I unplug/plug my USB headset

[Launchpad Bug Tracker]

You have been subscribed to a public bug:

Binary package hint: pulseaudio

Steps:

- I hear music ok; alsamixer shows level at 80% (for example)
- unplug the USB headset
- plug the USB headset again
- music is way too low; alsamixer shows level at 0%

The volume should be persistent across unplug/plug.
