Bug Description

Sudden absence of a audio output device(s) after updates or misconfiguration is a quite popular error in many Ubuntu versions. The sound configuration panel in unity doesn't offer any support to automatically detect sound hardware and install necessary drivers. I'd be nice if it did including the following functions:

  - Selection of backend. There's `alsa` and `jack` and possibly more and no reason to bother Ubuntu users with that except for one page in a guided dialog.
  - Auto-detection of hardware. Although non-deterministic because of "cheap" hardware which doesn't identify itself correctly as audio hardware, there should be a page in a guided dialog allowing selection for correctly identified hardware (including eventual workarounds for detection).
  - detection of necessary drivers and support for choice if there's more than one available
