Where are the LXDE sound preferences?

  • 772

I'm confused,how can I change the sound output in LXDE? There's not even a single option anywhere unlike other environments.

I've tried doing anything with alsamixerbut still nothing, the output device is the HDMI audio of a Radeon HD card.

Edit: As it Turns out i was able to change the ouput device, but i had to use Gnome for that and its Gnome Sound applet, that is log out and log in once in Gnome change the device, log out and log back in LXDE.

Now the question becomes Why can't i do this in LXDE?

lxde

    xfce4-mixer

    Lubuntu shares many components with XFCE. My suggestion would be to use the XFCE4-Mixer. This still gives you a lightweight solution compatible with the lxde ethos.

    enter image description here

    to install

    sudo apt-get install xfce4-mixer gstreamer0.10-alsa

    This installs the following limited number of xfce packages -

    exo-utils libgarcon-1-0 libgarcon-common libwnck-common libwnck22 libxres1
  xfce4-mixer xfce4-panel

    to run

    type xfce4-mixer in a lxterminal

    In Options Auto-Mute Mode

    It should be set as Disabled.

    xfce - Auto Mute Option

    pavucontrol

    Slightly more heavyweight - you could install pulseaudio and thus use the pulseaudio packages such as pavucontrol

    enter image description here

    to install

    sudo apt-get install pulseaudio pavucontrol

    This installs the following pulseaudio packages:

    gstreamer0.10-pulseaudio libasound2-plugins libspeexdsp1
  pulseaudio-esound-compat pulseaudio-module-x11 pulseaudio-utils rtkit

    to run

    type pavucontrol in a lxterminal

  2. First of all, try lspci and lsusb to check if the device you need is seen by the system.

    Secondly in alsamixer try pressing F6, which will let you choose the sound card (I really don't know if this is needed tbh).

    And another tip for alsamixer: it doesn't show all parameters when u start it, some are hidden on the right so you just have to go to the right to see them all, I believe there is an output chooser. And also in alsa see if you are viewing the needed items (F5 will show all parameters available).

    Hope this helps.

  3. I am using Ubuntu 12.04 64bits and I recently installed XFCE-4 Desktop. When I first logged in xfce-4 I noticed there was no sound at all (Rythmbox, games, etc). And I found no icon anywhere to adjust the sound.

    This is how I did to fix the problem :

    1) Go to the applications menu > Sound & Video > Mixer.

    2) In the Sound Card option menu, select Playback: Built-in Audio Analog Stereo (PulseAudio Mixer).

    3) The playback window may be empty. Click on "Select Controls..." , enable/check Master then close.

    4) Unmute the sound icon just under the volume bar.

    I guess you need to check whether you are using PulseAudio or Alsa drivers. This should not change the fact you need to uncheck mute icon in your "Playback: Audio stereo" in Mixer.

    I hope this can help :-)

    PS : I am a newbie in linux stuff, so please correct me if I said something wrong.

  4. This is what i did to fix the no audio issue in my ASUS laptop:

    sudo apt-get install xfce4-mixer gstreamer0.10-alsa

    This installs the following limited number of xfce packages:

    exo-utils libgarcon-1-0 libgarcon-common libwnck-common libwnck22 libxres1 xfce4-mixer xfce4-panel

    To run, type xfce4-mixer in a lxterminal.

    In Options:

    Auto-Mute Mode : Disabled (changed enabled to disabled)

  5. Lubuntu recently switched from the LXDE desktop environment to LXQt. So while not literally answering this LXDE question, in the spirit of it here's an answer for Lubuntu ≥18.10:

     

    You can use pavucontrol-qt, a Qt based implementation of the pavucontrol PulseAudio mixer mentioned in the other answer here. This fits nicely into the Qt-based desktop environment LXQt of the recent Lubuntu versions.

    pavucontrol-qt is the default mixer application that can be opened via the volume adjustment panel widget (though you can also configure a different one there). For some reason, it was not installed on my system (maybe because I always install Ubuntu first and then Lubuntu packages on top?). Anyway, you can install it with:

    sudo apt install pavucontrol-qt

    In the application, you can choose the sound output device under "Output Devices → Port".
