Usually they can be fixed by changing capacitors (thats likely the case in your example with failed analogue audio). Now, there is a lot of room inside a SB classic, likely enough to fit a Pi or my SqueezeAMP. You could also use a ESP32-A1S module and easily redo a full board around that. Ethernet might be difficult, though. The A1S design would be very simple as that module already has a DAC and an headset/line out. You just need a 5V to 3.3V regulator, not even a step down. Our SqueezeESP32 software I think give you all you want: display, IR and SPDIF. I dont have time dit such project but somebody with simple CAD experience can do it easily.
