this is a board of mine that's I've been trying to repair from time to time..
liquid damaged on right I/O.. after taking the I/O out and measure diodes and shorts on board I found everything OK except for SPKRAMP_INT_L readings were too high.. and sadly its associated with the T2 chip..
Days pass by and I'm now good with T2 chip.. so I've taken it out and put another one.. SPKRAMP_INT_L is reading OK now but no audio.. :| with known-good right I/O and known-good right I/O cable..
I've taken diode measurements.. and I've measured resistors for bad or blown resistors maybe somewhere.. And I could not find out the problem..
It might be an I2S line issue but sadly I do not own an oscilloscope :|
Other suggestions?
