maybe the channel for headphones was muted.
All of a sudden both my earbuds and wireless headphones stopped working. Only my external speakers were working. So I tried plugging the earbuds into other inputs on the computer and unplugged my speakers, then plugged them back in. Now they don't work either, so I have no audio at all. I need some audio device to work every day because I am in school and I need to access voice files to transcribe into Word documents. Help.
