Hi, I have a Toshiba Satellite C665D-S5200 laptop. And for the past year or so, I've been having this problem. I have explained the problem to my warranty repair people and nothing has been done. Basically, this is what happens: I can be listening to music, WATCHING a video, anything that requires sound and the sound through my speakers is perfect. Until, randomly, the sound stops. I GO into the Volume Mixer, and the bar is still moving as if sound is playing out of my speakers. (I do not have a separate INDICATOR for headphones, HOWEVER.) Finally, I realize, that if I plug in my headphones and unplug them (or any auxiliary sound device into the jack) the sound reverts to normal, but "breaks" soon after again.

This NEVER, ever happens while I am listening via headphones, or auxiliary speakers.

I have updated all my drivers multiple times. I have scoured Google. I have asked around, and I have no answers. If I knew what was wrong, I could fix it.

I am running Windows 7, and the sound driver is a Conexant SmartAudio HD. (I am not sure what my sound card is, it might be the same thing. I apologize for that.)

After a year (maybe two, I cannot remember) of this, I am at my wit's end. If anyone could help me, I would appreciate it.

Thank you for your time. If you need any more information, I am glad to provide it.
