Thread: Can't change sound volume of my laptop

    Post Can't change sound volume of my laptop

    Hello.

    I have recently installed Leap 42.3 on my Dell XPS 15, and everything seems to be right except for the fact that I cannot change the sound volume level. Basically, I do have sound (so apparently that is working correctly), and I can move the sound indicator level using the keyboard, but no matter what the volume level does not change. Also, I don't know if this is a related problem, but when I plugin my headphones they don't work, and my laptop don't switch of the speaker.

    This is my first time using openSUSE, so I don't really know what to do. I have checked some posts of people with sound problems, but most of them are related with the lack of sound.

    Some information/results of commands that might be helpful:

    Code:
    $ head -n 1 /proc/asound/card0/codec*
    ==> /proc/asound/card0/codec#0 <==

    ==> /proc/asound/card0/codec#2 <==

    I really appreciate any help or advice that you could give me.

    Sorry if this is teaching grandmother to suck eggs, have you tried configuing the sound channels? You may find you are configured to use HDMI rather than analog stereo. Right clicking on volume control normally opens up configuration options.

    Hey, thank you for your response.

    I have checked in the gnome sound settings, and the profile is set to Analog Stereo Output. Also, I checked using pavucontrol and the profile there is Analog Stereo Duplex. So, as far as I know I am using the analog stereo.

    Something that I have noticed is that although I cannot change the volume directly, if I set the volume using, for example, the sound configuration panel and then I restart the computer I get this sound level. But I am not 100% sure about this (it is hard to meassure the real sound level only by hearing).
