As a result, the device will sporadically show up in Google Hangouts in Chrome. Sometimes, it'll only show the mic and not the speaker.

This didn't happen with a similar device produced by Sennheiser. Would a patch for Plantronics devices as suggested in #28 fix it?

This is on 16.04.3 with -proposed enabled.

If this is a different issue, I apologize. It's hard to tell from the above.
