ALSA-only purists: Question, new GUI app for the mixer and EQ?

brocashelm · 2026-04-15 19:05:55

There is no one-size-fits-all theme, ever. People are still gonna complain.

golinux · 2026-04-15 19:17:25

No one ever said there was. But there are general rules that help to make content more accessible and conversely practices to avoid. One being low contrast . . .

brocashelm · 2026-04-15 19:45:09

Are you volunteering to do the theming for the software? No? It's his software, let him do whatever he wants.

golinux · 2026-04-15 20:15:38

Why are you accusing me of imaginary intentions? And putting words into my mouth or thoughts into my head.

I am sensitive to the subject because I have known visually challenged individuals since the 70s and have always tried to be as inclusive in my communications as possible.

greenjeans and I (and others here) go back well over a decade. . . Long before you came on the scene. So your perspective has very little relationship to history or reality. Neither does it provide value to others. It is just an amateur hit piece. Time to grow up . . .

brocashelm · 2026-04-15 21:53:05

Greenjeans already clarified he didn't hardcode any of that "inaccessibility" crap, and he did say he'll look into it, simply because he wants to help. It mainly comes down to which theme you use, as Rations mentioned. Wanting to cater to the visually impaired is nice and all, but it's not "mandatory", and hardly at all the end of the world because the current theme in use made it harder for you to tell things apart. That MATE screenshot was way more evident of visual issues.

The "historical relationship" is a moot point when you're just nitpicking over a theme's color and contrast defaults. That's why you can change it. Not a big deal.

Yep. Plenty themes out there to make everybody happy. I have old eyes myself, and my theme is the only one that doesn't strain them, so it makes me happy.

But this thread really isn't about theming, it's about sound and music, be great if we could get back to that. I was trying to talk about making a special version of AT to accommodate a fellow user with some hearing issues before I got accused of not considering folks with disabilities.

"Just a suggestion . . . Are you aware that the gray on gray is borderline to being an accessibility hindrance for a lot of folks? It also looks like there might be some blue there but the contrast is so minimal I can't really discern it."

You have an overactive imagination. I "accused" you of nothing.

Version 3.3-0 uploaded! This adds the dual-sliders for balance control in the mixer. I'll start on the dual-sliders for the EQ version soon.

https://sourceforge.net/projects/vuu-do … /AlsaTune/

Also new versions of Fatstick, Vuu-do App Info, and Scrotshot. Did a lot of house-cleaning today on the older apps.

i tried your deb pkg on void, i get this error:
Failed to load plugin "caps.so": caps.so: cannot open shared object file: No such file or directory

caps.so is under /usr/lib/ladspa/caps.so

i searched for "caps" in your source code but found nothing

greenjeans · 2026-04-26 16:58:29

Hi, so caps is a dependency for libasound2-plugin-equal so you won't see it in the source code as it's not called directly.
So to clarify, you do have the "/usr/lib/ladspa/caps.so" file? If so it's pretty puzzling that it can't find it....

I have never worked with Void and don't know much about it, my first thought is there might some differences, package names, methods, etc. in Void, possibly versioning issue, but it would sure be cool to have it up and running in it.

Was your error genned by running it using the .desktop, and have you tried it in terminal?

FYI this was all built on Devuan daedalus libraries, in limited testing it works here for excalibur as well but have not fully tested or re-built the binaries against excalibur/trixie libraries. So that could be an issue with versioning possibly.

caps - 0.9.26-1
libasound2-plugin-equal - 0.6-8
libasound2 - 1.2.8-1+b1

i get the error from the terminal, but the .desktop doesnt work either

i downloaded the 3.3 source and ran

gcc -o alsatune alsatune.c $(pkg-config --cflags --libs gtk+-3.0 alsa glib-2.0) -Wall

but its the same error as from the .deb

# this are the corresponding packages on void

xbps-query -f caps-0.9.26_3
/usr/lib/ladspa/caps.so
/usr/share/ladspa/rdf/caps.rdf

xbps-query -f alsaequal-0.7.1_2
/usr/lib/alsa-lib/libasound_module_ctl_equal.so
/usr/lib/alsa-lib/libasound_module_pcm_equal.so

i noticed that devuan has
/usr/lib/x86_64-linux-gnu/alsa-lib/libasound_module_ctl_equal.so
and on void it is here
/usr/lib/alsa-lib/libasound_module_ctl_equal.so

i tried to symlink the directory into the place:

sudo ln -s /usr/lib/alsa-lib /usr/lib/x86_64-linux-gnu/alsa-lib

ls -lah /usr/lib/x86_64-linux-gnu/alsa-lib/libasound_module_pcm_equal.so
-rwxr-xr-x 1 root root 23K 26.04.2019 21:03 /usr/lib/x86_64-linux-gnu/alsa-lib/libasound_module_pcm_equal.so

even after installing the deb libasound2-plugin-equal_0.6-8_amd64.deb
i still error:

./alsatune
Failed to load plugin "caps.so": caps.so: cannot open shared object file: No such file or directory

Hey my friend, sorry for the late reply, I was out for a couple days with a tooth infection and up to my neck in projects. Not having a Void instance in front of me it's really hard to troubleshoot, and from more reading about Void it seems to have a very different file structure in some ways. The error does seem to originate with libasound2-plugin-equal trying to load the LADSPA plugin "caps.so" at runtime. So maybe the loader needs an explicit hint about where to find LADSPA plugins. Maybe try:

export LADSPA_PATH=/usr/lib/ladspa

And if that doesn't work, try:

export LADSPA_PATH=/usr/lib/ladspa:/usr/lib64/ladspa
export ALSA_PLUGIN_DIR=/usr/lib/alsa-lib

You might also try adding "ldl" to the compile command when compiling from source:

gcc -o alsatune alsatune.c $(pkg-config --cflags --libs gtk+-3.0 alsa glib-2.0) -Wall -ldl

Try that and let me know, if it doesn't work we may need to run an strace to see exactly what's happening.

Thanks for giving it a try, i'm very interested to know if it can run on Void and if so what other steps/instructions I need to add for Void users, and again i'm so sorry about the delayed reply.

no worries im always late too, i hope you are better that sounds painfull

it compiled with either of those
but i the volume control does not load
i can hear the tone, but it is not affected by the eq

if you want, i do have a live snapshot that you could fire up in an virtual machine, and run "sudo xbps-install alsaequal caps"
unfortunately im to stupid to get a soundcard with qemu

greenjeans · Today 00:07:13

Sweet! we're almost there, the test tone shouldn't react to most EQ settings as it's just a straight 400 hz tone. What is the output if you open a terminal and type alsamixer?

Downloading the iso you linked to now, will try this in a live-session and see what's what.
