Comment 45 for bug 178442

Florian - the (partial) solution from #35 is still working for me - with the restriction that Pulseaudio updates usually overwrite /lib/udev/rules.d/90-pulseaudio.rules with a plain vanilla version so that I have to re-edit it to get things going again.

In general (looking at the Pulseaudio bug) there seem to be two problems with the solution that are preventing it being merged into PA:
- digital input needs to be sorted out (probably a mapping issue that just needs someone to take the time to test properly)
- the unused channels appear in the channel maps ("Output Devices" tab in PAVC) which is untidy and potentially confusing. This needs ALSA to be fixed apparently
