Minimalistic volume mixer.

mixxc's Issues

Volume percentages are inconsistent with other applications (ncmpcpp, pavucontrol)

I've been shamelessly stealing referencing your PA code for my own project and I've come across a bug in the way it's displaying volumes currently.

Using the libpulse LinearVolume seems to result in some weird not-actually-percentage value. I assume it's something to do with the log scale, and it's supposed to be linear to human hearing.

The issue with that is that just about every other volume program calculates the percentage differently, causing Mixxc to show very different values. For example, I'm using ncmpcpp for music and that allows controlling the sink input volume directly, and is always out of alignment. pavucontrol seems to agree with ncmpcpp and not Mixxc.

I have found another Rust mixer project which has a couple of helper methods for calculating to/from a percentage which seem to line up with the other mixers. I believe you could grab these and stick them in to correct this:

I've not managed to get anywhere with a PA client before now and I've been searching months for an example, so this has been a lifesaver. I hugely appreciate the amount of work put into creating this and I will definitely give the project a shout-out.

How to build it with gtk4-layer-shell feature?

Hi, thanks for the interesting project!

I have issue building it on my Arch, here is what I tried:

git clone --depth 1 <repo>
cd mixxc

cargo build --release --features=Sass,Wayland

output:

   Compiling gdk4-sys v0.7.2
   Compiling gsk4-sys v0.7.3
   Compiling gtk4-sys v0.7.3
   Compiling gtk4-layer-shell-sys v0.1.2
The following warnings were emitted during compilation:

odd focus and border behaviour when running in xmonad - xubuntu

Needed to sudo apt install libgtk-4-dev

Then installed with: cargo install mixxc --locked --features X11

Window pops up ok:

After some time it crashes, and I think if I change focus to another window it crashes instantly - here's the logs:

I'm not rust master but very experienced developer, so not afraid to get my hands dirty if required (might need a hand getting dev env set up 😅 )
