After playing shockwave flash audio content on websites, the sound will stop working a after a period of time. The amount of time it takes for the sound to stop working is random, but it happens consistently. It affects all sound, not just flash content. I having a hard time finding a process that is causing the problem, but the sound will come back while I log off of the computer (the logoff sound plays), so it seems there is something running that's interfering with audio.
I'm running Windows XP SP3 and the version of Flash is 11.1. I'm using IE8, although the problem occurs with Chrome as well. The motherboard is Intel D865GVHZ with onboard sound (Realtek).
Ideally I would like to know if there's a process that I can kill that will bring the sound back. I'd like to avoid a bunch of software uninstalls/re-installs unless there's a known issue that will be resolved by doing this.
