Laptop Sound issue (asus k450jf)

Hi guys,

I have a problem with my laptop, my sound is not working.

Its not a hardware problem.

When i boot to arch, on the gdm screen i can have sound, but only on the first boot (not after a screen lock or something like that), but when im on my DE (Gnome) i dont have any sound.
I tried to reinstall alsa-utils and removed the gnome extensions, but still nothing.

Can someone help me plz? big_smile

Some outputs:

Re: Laptop Sound issue (asus k450jf)

Apparently your sound configuration is being modified when your session is loaded.
After what I've read: pulseaudio has become a dependency of gnome. You could compile gnome without pa., but I cannot tell you how: https://bbs.archlinux.org/viewtopic.php?id=211137

So, assuming your pulseaudio server is running but is falsely configured, you will not hear any sound even if your alsa layer was configured correctly.

Since I am a newbie and do not want to spend my time debugging and working around an additional pulseaudio layer, I play it safe running a pure alsa system without pulseaudio.
This requires a DE without requiring pulseaudio as a dependency or disabling pulseaudio https://wiki.archlinux.org/index.php/Pu … altogether and configuring alsa https://www.alsa-project.org/main/index.php/Asoundrc . This should be easy, since you already printed the information of your soundcards and subdevices.

On a fresh install I did not create a home/ .asoundrc, but only a /etc/asound.conf just containing:
defaults.ctl.card 1
defaults.pcm.card 1
defaults.pcm.device 0

You have to tell audioplayers like vlc to access alsa instead of pulseaudio (for ex. through the gui). Thanks to recompiling efforts of the arch community the alsa sound output for Firefox worked out of the box, which is officially not being supported anymore.
