Hi David,

Thanks for the suggestion.

I tried the latest version but the headset mic still doesn't work.
Are there any particular settings I should be configuring to make this
work?

Note that the jack detect is working for the output.  When I plug in
the headset, it switches the playback from the speakers to the headset
automatically, and I see the 'Connector' drop down in the output tab
of the Sound settings switch between "Analog headpohones' and 'Analog
speakers."

It seems there's still a problem detecting that the headset also has a mic.
