hello, i have a dell inspiron 14 with windows 7. when i unplug my laptop from its power source, the sound occasionally just mutes, and doesnt come back on unless i turn the volume up manually, and then after a few minutes, the sound goes off by itself again. it doesnt do this when its plugged in, does anyone have any idea why this is happening?
