Hi everyone! I have a problem with my HP Stream 11 Laptop (11-ak0023ng) yet again.
Originally, a load switch on one of the USB ports had blown up and the laptop would not power up. The original post can be found here:

I replaced that load switch with an original replacement part and the laptop starts up and works fine again except for one thing: when testing the device the sound was crackling badly and I noticed the Realtek ALC3247 sound chip was really hot (can´t touch for more than a second). While testing I had the keyboard assembly (top cover) still sitting loosely on the laptop. It might work as a heatsink to the chip if properly put together but I doubt that it would be normal for the audio IC to get red hot without a heatsink...
None of the capacitors around the chip are shorted but clearly there is something wrong here. Is there a connection to the load switch incident? I can´t find a schematic to check any component values around that chip so I thought I might ask for your opinion. Should I replace the IC or is it likely the problem lies somewhere else and will come back again?
