Problem to listen kag sound AND other sound

Hello, i have problem, when i launch KAG (i'm Linux user), it's impossible for example to listen music with firefox, KAG block other sound output. Is it possible to change that ?

 

Same problem in win10

 

Always. But it's the first time i repport this bug.

 

Hmm.. in the windows preferences for sound devices there's always an option to allow apps to take over exclusive rights of that device. As far as I know KAG doesn't do it anwyay but you could try that. In Linux I don't know, there are many possible combinations of sound card, driver etc

 

That or for some reason KAG is somehow claiming the ALSA device for your speakers than just using the pulseaudio ALSA mixer. Did you ever touch such settings?

 

It's the same problem with other applications. And i have already checked volume in alsamixer, but all is in max. And i use pulseaudio.

 

Does KAG show up in pavucontrol? Does anything odd happen in pavucontrol when KAG starts up?

 

No, KAG isn't showing

 

Yeah, sounds like KAG is claiming the entire sound card through ALSA for some reason instead of going through pulse. It could be due to bad defaults on your end maybe? What distro?
We don't have much control over what happens under the hood because IrrKlang abstracts it. I wouldn't be surprised if it just did something weird.

 

I have Gentoo Linux.

I have this setting, but i have again this problem. I have trying to set 4 for alsa, but the same problem, other sound application don't work if i don't stop kag.

 

You should check your ALSA defaults so the default is the pulse output then. This way KAG audio will go through the pulseaudio daemon and back to your speakers through its ALSA output.
The reason is that (without dmix, etc.) only one process can access a hardware ALSA output at a time. If KAG tries to claim the ALSA hardware output directly then only either pulseaudio either KAG can use it, not both.
I am not sure why would only KAG be affected by this issue on your end, but firefox for example uses pulseaudio directly by default (without going through the ALSA pulse output).

 

How i check if Alsa is the default pulse ?

This is what I have on my arch linux box in /etc/asound.conf :

Code:

# Use PulseAudio by default
pcm.!default {
  type pulse
  fallback "sysdefault"
  hint {
  show on
  description "Default ALSA Output (currently PulseAudio Sound Server)"
  }
}

ctl.!default {
  type pulse
  fallback "sysdefault"
}

# vim:set ft=alsaconf:

Do you have anything similar in /etc/asound.conf? If not, backup that file and try copy pasting what I have here.

You will not find options for this in KDE. The sound applet is a pulseaudio sound applet, it does not manage ALSA stuff.

Just in case I will explain it over in french to make sure there is not a misunderstanding (better answer in english in forums though)
// Le soucis n'est pas du côté de pulseaudio à priori mais de ALSA. Il faut qu'ALSA soit configuré pour utiliser par défaut la sortie pulse et non de tes hauts parleurs. Si KAG essaie d'utiliser la sortie des hauts parleurs directement via ALSA alors pulseaudio ne pourra plus l'utiliser et donc plus générer de son.

Also before trying that out since you are running Gentoo, make sure that you have this alsa-plugin USE flag set for pulseaudio and have media-plugins/alsa-plugins installed as described here:
https://wiki.gentoo.org/wiki/PulseAudio#Global

I am not familiar with Gentoo though.

 

I have coppied your setting file, now it's okay, when i use kag and other sound, for example firefox, it's work together !

But now i have other problem, just sound system don't work. For example, when i remove file to trash, system don't play any sound ...

 

No idea about that one. Try to tweak audio settings in the KDE control panel.

 

Solved ! Just follow this configuration file:
