I have Jitsi for OS X 2.4.4997 and a headset Plantronics500.
The headset works perfectly with skype but I would prefer to migrate fully to jitsi and drop skype altogether. Sadly, the microphone of my headset is not picked up by the present jitsi. I use a XMPP address, like the person I call. If I use the built-in microphone of my MacBookProRetina, jitsi there are no problems, apart from the not so great sound the other person hears from me.
Can you please help?
