When the Alienware Sound Center is running, SWL has no sound.
In order to get sound, I have to exit the Alienware Sound Center (in my System Tray) before starting SWL. I don’t know if this will get fixed, so I thought this workaround might be helpful for anyone else having this problem.
We had a long post on this awhile back when myself and a few others noticed our sound would work randomly and finally figured out it was the Sound Center. Apparently the issue pre-dated even before then and I am not hopeful for a fix. For now just remember to exit out.
