Using a Microsoft USB headset. Sound is very low and if I crank up the volume to the max is sort of audible but distorted and noisy. I have a 14.04 Xubuntu and a 15.04 Xubuntu instance on the same Virtualbox, using the same headset, and the sound is perfect. I also have an Arch instance with kernel 4.2.5-1 on the same Virtualbox and the sonud on that one is also good. This issue seems particular to Xubuntu 15.10. I posted this on the forums about 3-4 weeks ago in the hope that someone may have figured a way to fix this. No answer yet.
