Look into mumble. It’s NOT a discord replacement but does provide a good quality, low latency, OSS voice chat. Mumble + Signal group chat is what my friends and I use for gaming. Seems to work well.
Tip: Turn on text-to-speech to get narrated announcements when users join channels. Also works for text chat shenanigans. 🤣
Is the drive totally dead? Curious what SMART would report.
My gut feeling is that it’s probably cheaper to buy a replacement m.2 than the hours of time to get netboot working but it could be a fun project!
