[Sound Block] Supporting different audio setups about i3status-rust

[NullVoxPopuli]

oh and cargo/rust:

 $ rustc --version
rustc 1.17.0 (56124baa9 2017-04-24)
 $ cargo --version
cargo 0.18.0 (fe7b0cdcf 2017-04-24)

also, I installed the font awesome fonts via:

sudo apt install fonts-font-awesome

My bar is:

bar {
  font pango:DejaVu Sans Mono, Icons 8

  status_command /home/me/.i3/i3status-rust/target/release/i3status-rs /home/me/.i3/i3status-rust.json --icons awesome --theme solarized-dark

  position top
  colors {
    separator #666666
    background #222222
    statusline #dddddd
    focused_workspace #0088CC #0088CC #ffffff
    active_workspace #333333 #333333 #ffffff
    inactive_workspace #333333 #333333 #888888
    urgent_workspace #2f343a #900000 #ffffff
  }
}

Hey, start by removing the sound block from your config, I'll fix it tomorrow.

[NullVoxPopuli]

thanks!

What's the output of amixer get Master on your system? The sound block currently only supports amixer.

[NullVoxPopuli]

$ amixer get Master
amixer: Unable to find simple control 'Master',0

my regular i3status (which has a work volume indicator) is formatted like this:

volume master {
	device = "default"
	mixer = "Master"
	mixer_idx = 0
	format = "♪ %volume "
}

not sure if that helps

[greshake]

Just $ amixer please... Currently the sound block only uses Master, which doesn't seem to work...

[NullVoxPopuli]

$ amixer
Simple mixer control 'Mic',0
  Capabilities: cvolume cvolume-joined cswitch cswitch-joined
  Capture channels: Mono
  Limits: Capture 0 - 52
  Mono: Capture 44 [85%] [-27.00dB] [on]

See, I'm not very familiar with the sound systems in Linux. Your main audio output is apparently not using amixer, so you can either switch to a system that enables you to use amixer or add functionality for your setup to the sound block, and hit me with a PR, that way others with your setup may profit. Good luck, I hope for contributions! :)

[NullVoxPopuli]

I'm not familiar with linux sound either. seems to be a bit of a mess.

I think I'm using pulseaudio

[greshake]

I am, too. But there are usually multiple subsystems working together, going from hardware to the highest software level abstractions, provided by pulse.

[greshake]

Looking through the sound system part of the Arch wiki, it appears the Alsa system is indeed very ubiquitous. The arch wiki also suggests using amixer or alsamixer to adjust volume etc.. I'd suggest you check your setup, maybe you can fix it easily :) There definitely should be a 'Master' output listed when calling $ amixer.

[NullVoxPopuli]

Cool, I'll do some googlin' and post my findings here

[jm355]

I fixed this issue by installing pulseaudio-alsa on manjaro linux, maybe that'll work for others as well

[moritzheiber]

@greshake Is there are reason you're not using alsa-rs but instead are calling amixer directly? I would need to pass additional parameters to amixer on my system (my soundcard is on index 1 instead of 0), I would reckon a proper API would make it easier to add other configuration options?

@moritzheiber I don't believe we were familiar with that project at the time, but it's a nice find. I'd be happy to see some work moving towards using that library instead of shelling out. It might fix some of the issues I've encountered when hotplugging audio devices, too.

I consider this closed by #245.
