As I discussed with Tanu Kaskinen yesterday, we should do something
about when one profile path prevents another from using the hw volume
capabilities. However, with Ubuntu a few weeks from release, I went for
the workaround approach and created a separate profile for the devices
instead to minimise regression potential.
So, until this is fixed the right way, feel free to use the attached patch.

Subject: [PATCH] alsa-mixer: Add workaround for some USB headsets
This is a workaround - these usb headsets have one output volume
control only, labeled "Speaker". This causes the default profile
set to not control the volume at all, which is a bug. Workaround
that by creating a separate profile set.
