I installed Lubuntu on my laptop, and it is working extremely well. However, I cannot figure out how to add applets to the panel. In particular, I cannot add volume control, so I cannot figure out how to change my volume (which is currently muted).

Also, my function keys no longer work (which is not surprising). How can I make it so that I have control over the volume using the panel applet and my function keys?

Thanks for any replies.

Update: After testing this out with other applets, I found the problem is that volume control is not visible. How can I make it visible?

Update: I played with alsamixer and found I have no sound. How can I fix this?

Update: Here is the output of pulseaudio

E: [pulseaudio] module-alsa-card.c: Failed to find a working profile.
E: [pulseaudio] module.c: Failed to load module "module-alsa-card" (argument: "device_id="29" name="platform-thinkpad_acpi" card_name="alsa_card.platform-thinkpad_acpi" namereg_fail=false tsched=yes fixed_latency_range=no ignore_dB=no deferred_volume=yes use_ucm=no card_properties="module-udev-detect.discovered=1""): initialization failed.

I figured out how to fix the problem. For anyone else who has this problem: be sure to change the default volume card. Here is how you can do that:

  1. Type Ctrl + Alt + T to start LXTerm
  2. Type sudo leafpad /etc/asound.conf
  3. Type Enter
  4. Copy and paste

defaults.ctl.card 2

defaults.pcm.card 2

defaults.timer.card 2

into the file.

Change the number 2 to the sound card you want to use, then save the file and restart your computer.
