I have a very weird problem. Toshiba laptop, running windows 7. So I can put on a youtube video and it works for a while, after a few minutes, the audio stops playing through the speakers...its playing one minute and then complete silence the next. The video is still playing and no sounds will work (clicking the speaker icon to "ding" or any other video at this point). Now here is the weird part...if I plug in a headset or speakers into the speaker jack, I can hear the audio through the headset or speakers. Then if we unplug it, the speakers start playing again. I can replicate this issue exactly over and over. The audio usually takes anywhere from a minute to three minutes to stop. We have already completely uninstalled the audio driver and re installed(latest driver from toshiba based on this exact model).
I think it might have to do with faulty headset detection. The audio jack has been cleaned and dusted.
