So I have a Sonos Arc that is not fully working. Here is a short backstory. This unit was not producing sound even everything else seem to be working, I've decided to try to repair it myself. After disassembly, on the PSU/Amp board I found few blown capacitors and some dead DAC chips, I have replaced everything that looked suspicious and the unit started to produce sound, unfortunately it resets the volume to 15% all the time, as I read this indicates a fault somewhere in Amp circuit. As I don't have access to any documentation or spare parts, I don't think it's possible to repair for me. I'm not interested in paying someone to repair it either, I'd much rather turn it in some sort of DIY solution.
What I'm looking for is some kind of electronics project that would be able to drive speakers that left from arc. Ideally to be able to preserve surround and eARC connectivity, but that is optional.
I've tried looking for some ready solutions on the internet, but frankly, felt overwhelmed as I don't have knowledge on audio equipment, but willing to learn it.
Can anyone recommend anything for this use case?

I have a thermal camera, and nothing gets hot out of spec when it's running (max I've seen is DAC chips are getting to 50C which is nothing according to their datasheet), my assumption is that some component got partially damaged during the event that caused the components to short, but it's not obvious, e.g. value have drifted or something like that. Unfortunately, this kind of issue is really hard to detect without known good reference at hand or documentation.
