Sound is gone

Hi,

This is two days old arch linux installation. I am using Dell Inspirion 6000 laptop. Sound worked fine until it suddenly started not working. By not working, I mean that I cannot get sound from any application I use. This behaviour persisted after a restart.

Both xfce audio mixer and pavucontrol thinks that everything is fine, but I am not hearing anything. This is how pavucontrol looks;

I am using alsa and pulseaudio with default settings. (I don't remember modifying any config files.) Here are output of some possibly usefull commands;

[yasar@yasar-laptop dev]$ speaker-test -D front -c 2

Something on your computer changed. Did you do an update with pacman since sound was last working? What packages were updated?

Also, check the volume levels.

Re: Sound is gone

I actually found the problem, pressing mute key on my keyboard mutes Master and PCM channels, but pressing it again only unmutes Master channel but PCM channel remains muted.

I don't really understand how sound channels are supposed to work. But currently both master and PCM channels needs to be unmuted and volume level should be increased in order to get a sound. Is it how sound supposed to work?

Is there a way to fix this problem? I would like to get rid of this PCM channel altogether if it is an option. If not, how can I fix the keyboard shortcut that handles mute/unmute?

How have you set up the mute key?

Re: Sound is gone

I didn't set it up, it just worked out of the box. The setting also don't show up on xfce4-keyboard-settings

Re: Sound is gone

Solved: Install xfce4-pulseaudio-plugin : https://aur.archlinux.org/packages/xfce … io-plugin/

It is a panel plugin. Use it instead of audio mixer panel plugin and it will solve the problem.

STOP posting oversized images. Read the Forum Etiquette I linked to. Again.
