I literally have no idea what happened, had a stable install going was using it fine then bam this started. Purged all installed directories and it continued. Even reinstalled ubuntu and its still happening. It does not happen in the windows partition on the same computer. Speaker output works fine. I am literally at a loss and very sad because I really want the headphones to work . Any advice / has anyone seen/heard of this problem before??? Seems awful bizzare. Also tried another pair of headphones, both pairs I tried are verfiied working on the same computer in windows.
