The headphones are 3.5mm so they do not have their own audio driver like USB headphones do. I am using Windows 7 and the latest audio drivers. It seems as if Jabber is defaulting to the built in speakers audio device despite the headphones being connected as the primary device. I have noticed that when this happens briefly I will see two audio devices listed when I click my volume control icon.
After the jabber tone is done the streaming audio goes back to my headphones. To make things worse, while the jabber tone is playing it also redirects all other streaming audio such as my music to the internal speakers so for 1-2 seconds everyone around me can hear the jabber tone and my music. When receiving a new Jabber message while using headphones, for some reason Jabber defaults to using the built in laptop speakers and NOT my headphones. I have Jabber set to use an audio notification when I get messages. While I work I usually listen to music over headphones. I had it on my HP EliteBook 8460P and now also have it on my HP EliteBook 8470P that I use so I know the issue is not limited to a single computer. I am having an audio related issue with Jabber.
