The HipChat video functionality basically embeds Chrome browser, that's how video support is provided. After working with the HipChat video architecture team, we found that the buzzing noise problem while making a video call is actually something on the WebRTC layer in Chrome. 

The problem seems to be Macbook Air specific, we've made multiple tests with the final user on more than one machine, and the problem was replicable. The buzzing noise is only gone once the Bluetooth device (Plantronics Voyager Edge for Mic and Speakers) is disconnected. 

This has also been tested with different video platforms - other than HipChat, which means no Chrome embedded - on the same machine/environment, to rule out other possibilities.
