Not in my case... I do not have any SD cards mounted, one USB port in use for mouse, no other hardware attached... Of course is not an AOA110, but HP 6715b, but having same problem... Filed a new bug at https://bugs.launchpad.net/ubuntu/+source/linux/+bug/560966 Sometimes I do hear a strange sound before hanging from speakers, so maybe the problem is pulseaudio...?
