Bug Description

Lsusb ID: 046d:0a1b
...as well as another I have at home, has just a "speaker" mixer control and nothing else, which seems to confuse PA into believing it can't control volume at all. We probably need an udev rule and a separate mixer profile to solve it.

Just to summarise today's thoughts.

There is one output volume control named "Speaker".

We can either fix this in the driver or in PulseAudio.

Driver: We have a generic problem of that the names picked for mixer controls are in general *not* compliant with the standard volume control names as specified in linux/Documentation/alsa/ControlNames.txt. We can either try to fix the generic problem, or create a quirk for these devices that changes the name.

PulseAudio: We have a generic problem in that PA disables hardware volume control if one of the mixer paths does not have a volume control. In this case, analog-output does not pick up "speaker" as a volume control, whereas "analog-output-speaker" does.
* We can try to fix the generic problem by
- fix the original problem and see what bugs we'll suffer from if we don't unify has_volume
- disabling the profiles without hw control instead of disabling hw volume control.
...or we can create a quirk for this device by writing a PA profile set and a matching udev rule.

One problem, five fixes to choose from. A difficult decision.

Hi David. Good job! So which solution did you pick, finally? :-)

Given the tight time-schedule of Natty (due to me ignoring this bug for too long) I went for a workaround that tackled a few specific ID's only, i e a PulseAudio quirk. Should be in Natty as of today.

@Ipeacocks, this is about USB headsets and as such the bug is in this case independent of the main machine. Please file a separate bug for your issue.
