Hey Mark-sf,
As for the resistor, it was r101(!), which is the same resistance of 390 ohms. I will add a picture of the resistor before it was replaced.
I measured for DC output:
Left channel: 24.48
Right channel: 0
I played around with all the sliders, volume, bass etc.. No changes.
The character of the noise is ver loud crackling and buzz/humming.
Could it be the right IC module?
