yes, maybe i will try. This is one of those fairly simple glitches, but not very quick fixes. Unfortunately, in order to be 100% sure of everything, service equipment is needed. But, first, move the entire motherboard to the service housing in cases of accessory errors. Change and check the operations. There is a good chance that the fault will not appear. In this case, it remains to replace the docking tape or the main speaker. Most of the time, it's the small interface problem that's soldered in the middle of the tape - the one you've already struggled with.
Otherwise, remove the motherboard - desolder the sandwich and check the entire interposer, compare the readings to the patterns, and finally focus on the Audio loop and the south amplifier. You will need an oscilloscope - check the digital outputs, data buses and their values. Unfortunately, you won't find short circuits in the installation here (I'm afraid it doesn't work as you think and as YT shows). Here, you really need knowledge and experience in the field of microelectronics.
