A cheap solution that might solve your volume problem is to add on an adapter that features a volume rocker dial. You can plug that into your phone and then plug your headphones into that adapter.
Something like the below screenshot. Hopefully it won’t muddy audio quality, so check this out and see if it’s something you can give a go.
Haven’t heard of that before, although I will state I’ve never had a mouse die on me (only been PC gaming for under 10 years). Do you have another machine to test it on?
