If I mute and unmute the sound manager I hear a "static-like" click in the headphones. The headphones are brand new and the problem was occuring with my older headphones as well. I have no speakers for my computer. If I do nothing then I will hear (every few seconds) a click first in the left side of the head phones then the right side. The sound will continue to alternate like that. In the past booting into windows (I am dual booting) has fixed the problem although the sound was not working in Windows 7 either (only after I restart and boot into Ubuntu for a second time does it seem to work). It should be noted that simply restarting my computer and booting into Ubuntu does NOT fix the problem. Could Win7 be toggling the sound? I am unable to kill the pulse audio process. It has a "nice" rating of -11. UPDATE: I just tested my "Windows is killing my sound" theory and it seemed to hold true. I restarted my computer, booted into Windows 7, then restarted my computer and booted back into Ubuntu. Sound now works. Here's my recent timeline: Last night booted into Windows 7; turned off my computer and went to bed. This morning booted into Ubuntu to discover no sound. Restarted my computer in hopes of fixing the problem; still no sound. Restarted my computer and booted into Windows 7 Restarted my computer and booted into Ubuntu. Sound works! Hope this helps...
