This is good. It says the SSM2044 is not broken.

Basically I still think it is something not very troublesome; maybe the
low/mid/high-Levelswitch or the volume potentiometer is dirty or (in
worst case) broken. But both you could temporarily heal by bridging them.

You may try to measure (or listen with an cable) to the following
testpoints:

These show the pcbs from the solderside, so you don't have to remove the
pcbs from the front. The testpoints are marked yellow.
