We are switching to the 6440 moving forward and out of the 3 that I've had in hand so far, all 3 have a random internal speaker pop. Audio plays fine, both internal and external. There's no distortion or crackle. I've updated the driver to no effect.
I can't replicate the pop and it's not just from system sounds. It pops when I just open a browser or click on start, etc....things with no audio associated. We're concerned that the internal speaker is not shielded properly and that it can lead to long term issues. We'll be ordering hundreds of these laptops over the next couple of years.
I've never had this issue with any of the previous models from the 6400 to the 6430S. Any idea what could be the culprit?
