Windows 7: Internet Sound Problems

I've posted about sound problems a lot in the past couple weeks. The DPC latency on my laptop was spiking severely. I somehow got the latency to calm down. Now I get spikes occasionally. But, the sound when on the internet still drops out and pops. When playing something on YouTube, if I search something in the address bar on Chrome the sound goes out. If I close other tabs, the sound acts up. While I'm using Chrome, I have the DPC latency checker open so I can see if it spikes when the sound goes out. It doesn't, anymore. Latency is fine, internet sound goes out. I don't understand it. Anyone knows why this could be happening?

A friend had trouble with chrome sound, he tried Firefox then it worked fine.
