To handle part of #118.


This is a pretty raw list of misc. files of interest in the current-most release.

Anything not listed here can be assumed to be specific to their setup (e.g. A/B, grub, archlinux, etc).

Tweaks

Audio


The main standing out thing is the noise suppression filter chain.

Other than that, hardware-specific tweaks (and probably unneeded bluetooth tweak) for audio stuff.

Finally, the "tweaks" section, most of them I won't pretend I know whether or not they are good, but I am confident enough to say that the vendor must have observed it being worth doing.

I'll be waiting for your takes on that.

/misc/sysctl.d/30-vm.conf

Long gameplay sessions can sometimes feel like a gamble regarding stability. That’s a very common problem for emulators due to how they have to handle memory in unique ways to match two completely different systems. This was especially true for Linux users, who had to rely on increasing the size of the vm.max_map_count kernel parameter for certain games to avoid out-of-memory crashes. Since the emulator needs to create placeholder memory mappings to keep up with the virtual memory requirements of the game, it wasn’t hard to saturate the default value, resulting in a crash once the placeholder mappings outnumbered the max mapping count.

Audio

I've noticed that Steam Deck with SteamOS sounds louder than with Joivian-NixOS. This is probably the reason why

There's nothing in there that should affect volume. As for vm.max_map_count, we set it higher than default, but lower than vendor.

That's for the microphone, not for the speakers.
