Hi,
when i mute the audio of my notebook (muted from kmix in tray icon), and also unmute that, it remain mute. It remain mute after i unmute it from kmix in tray icon.

In order to have audio working, i need to open "alsamixer" in terminal and in the "pulseaudio card" that alsamixer show me, i must to unmute it. Every time!

I don't know how to solve. Have you any idea? It could be a bug of pulseaudio?

Thank you!

Hello,
it is Pulseaudio who control the sound card and the master volume. Kmix is an Alsa compatible application. It can not control Pulseaudio. You should only use Pavucontrol or an other Pulseaudio mixer control for the sound level.

Pulseaudio control the sound per card and application. You do not need anything else if Alsa applications are redirected to Pulseaudio. I do not think it's a bug.

To use Alsamixer or Kmix you are better to disable the pulseausio USE flag. It will become impossible to have sound through Bluetooth with Bluez 5. There is no Alsa mode in Bluez 5. Pulseaudio only will support Bluetooth audio, for headset only, there is no Bluetooth microphone support.

You have Paprefs to setup some options of Pulseaudio, Pavucontrol for a Gtk mixer, you have the command lines mixer Pamixer, you have a usefull system tray applet that I cannot find by name. Emerge or Eix should tell you everything.

paprefs has been considered obsolete by pulseaudio upstream.
Wrt. command line tools, you forgot to mention the obvious - pactl.
Also, wrt. pulseaudio on KDE, doesn't phonon default to pulseaudio device, if it detects one ?

i need to control audio with function-keys of laptop. Now that i removed kmix, i can't do it.
function-keys are more handly than command line tool.

It seems strange that there isn't that tool for kde... in that case, i remove pulseaudio and use only alsa.
