Sorry for ressurecting an old thread, but this is a problem that I wanted to solve and I would like you guys to help me understand the part in question:
I did a bunch of experiments and I found that applying air to the soundcard solved the issue, I went a little further by getting a CO2/Compress air can and started applying air to each capacitor, chip , one by one until I found the culprit.
Yellow is the area of the problem
Green is the 2ndary problem
Red is the main culprit
can someone Identify these 2 parts of the soundcard? Upon applying air to this area the sound of the popping completely disappeared. I touched the Green part and it was extremely hot for a soundcard component (and I am questioning why there is no heatsink on here). Now I touched the red part and I almost burned my finger. the feeling is like putting your finger in a boiling kettle of water. the temperature there is close to if not more than 100 degrees Celcius. I thought only GPU components took that kinds of operational temperature. Also as soon as i touched that part the popping sound disappearned and reappeared about 4 seconds later.
BTW this is the video of the sound that I am hearing.. The mouse clicking is me changing the mode from entertainment to gaming back to entertainment.
