After Hours

Hello,

I have experienced issues with my sound card TWICE! This is not what I was expecting. First time it happened I have deemed the laptop as faulty and returned for a refund. Now I am experiencing same issues on another laptop.

Both laptops seem to have the same sound card: Conexant 20672 so this may be a glitch for this sound card model. However, I really want to know what is going on.

I have uploaded two videos. Please review and if you can explain or point me in the right direction (disscusions on other forums, tech articles) I would appreciate.
