alsa-related issues

[mackdroid]

hello there whenever i try to launch the panel i get this error
i use pipewire if that helps as it looks like its related to audio

anything else ill be willing to provide

[nwg-piotr]

Make sure you've got alsa-lib and alsa-utils installed. If so, please paste the output of the amixer sget Master command. Also: what Linux distribution do you use?

[mackdroid]

amixer: Unable to find simple control 'Master',0
and i have a mixer named IEC958 also i use arch linux

[nwg-piotr]

i use arch linux

You mean amixer scontrols returns something like:

Simple mixer control 'IEC958',0

?

[nwg-piotr]

Would you be able to install manually and tell me if my fix works on your system?

[mackdroid]

Yes I do have it installed

[mackdroid]

Okay let me try now

[mackdroid]

this is the error i get now

[nwg-piotr]

First of all: please provide the output of amixer scontrols. It usually looks something like this:

$ amixer scontrols
Simple mixer control 'Master',0
Simple mixer control 'Capture',0

but on your machine must be different, and I need to know details.

[nwg-piotr]

The commit above should prevent the panel from crashing on your machine, but the volume slider probably won't work. We need a workaround:

• Check the name that appears in your amixer scontrols output instead of Master;
• open the ~/.local/share/nwg-config/defaults file:

{
  "master": "Master"
}

and replace Master with the value that exists in your system;

• restart the panel;
• tell me if it helps.

[mackdroid]

sorry for the delay, but the panel now launches but as you mentioned the volume controls dont work

[mackdroid]

this is what i get when i try to change the volume

[nwg-piotr]

First of all: I still need to see the output of the amixer scontrols command. Please do type it in the terminal and show me what it prints. I can't reproduce the problem on any of my machines, so we won't take a step further w/o your help.

Secondly: have you tried to edit the ~/.local/share/nwg-config/defaults, as I mentioned above?

[mackdroid]

Output of amixer scontrols
Simple mixer control 'IEC958',0

Yep and I've replaced Master with IEC958

[mackdroid]

Also do you by any chance have discord? I'm active there so you would be able to get a faster response

[nwg-piotr]

Just 1 line? Strange.

Also do you by any chance have discord?

No, I only use Google Hangouts, And whatever we write here, will be available for future troubleshooters.

[nwg-piotr]

Sorry, it got closed automatically on the latest merge.

Could you try installing manually once again?

[mackdroid]

alright
yea i only have one line

[mackdroid]

well the volume slider does not work and i get this instead now

[mackdroid]

also you can use pamixer if amixer doesnt work
it works great with pipewire

[nwg-piotr]

also you can use pamixer if amixer doesnt work

This would be the 3rd method, as we now use python-pyalsa if available, and amixer as fallback. It doesn't make sense to do it this way.

I need to check if we could rely on pamixer as the only method. Would you be able to clone and install from another branch, in case it turns out to work for me?

[mackdroid]

Sure

[nwg-piotr]

Alright, it works, at least on my old testing laptop. Can't test it better here, it must wait till I'm home. Take a look, please.

git clone https://github.com/nwg-piotr/nwg-panel.git -b alsa
cd nwg-panel
sudo ./install.sh

[mackdroid]

alrighty

[mackdroid]

oh wait never mind im dumb its a missing module

[mackdroid]

the panel does launch but now the brightness controls dont work, i do have light installed and it says this
Couldn't set brightness, is 'light' installed?

[nwg-piotr]

Yep, see dependencies.

[mackdroid]

but i do have light installed

and brightness controls used to work

[nwg-piotr]

Check if this returns 0 on your machine:

$ light -S 20
$ echo $?
0

[nwg-piotr]

One way or another, you may clone again. I did quite a massive code clearance on the alsa branch.

[nwg-piotr]

Resolved in v0.1.7
