I have a question similar to the below, none of which solve my problem:

I have these speakers. Here are the results to aplay -l and lspci | grep -i audio 

:~$ aplay -l

:~$ lspci | grep -i audio
00:1f.3 Audio device: Intel Corporation Device a2f0

I've tried removing and reinstalling drivers:

# audio
sudo apt-get install dkms
sudo dpkg -i Downloads/...
sudo apt-get install -f
# or remove / reinstall drivers
sudo apt-get --purge remove linux-sound-base alsa-base alsa-utils
sudo apt-get install linux-sound-base alsa-base alsa-utils
sudo apt-get install gdm ubuntu-desktop
sudo apt install pavucontrol

Nothing is working so far--so any help would be appreciated. The speakers do play sound when plugged into my work laptop--a Macbook Pro--so I don't believe it's a hardware problem.

  • As you did not mention it specifically, I will ask. Did you check the Volume Sliders in whatever audio GUI you now have? You could also use '$ pacmd list-sinks' to get that info from the system. –  May 31 '17 at 06:38
  • @WillemK Yes, I have adjusted the audio sliders both within Ubuntu and the manual knob on the speakers... As I mentioned, I think (not 100% since I'm still pretty new to Ubuntu) the problem is that the computer is not recognizing the speakers as being installed / plugged in. – alexwhitworth May 31 '17 at 14:51
  • What did the command 'pacmd list-sinks' show you? Google for pacmd examples, they can be helpfull. –  May 31 '17 at 15:28
  • @WillemK packmd list-sinks gives 2 sinks, one active one idle. both have volume and are not muted, seems pretty normal – alexwhitworth Jun 02 '17 at 04:17
  • is the active sink showing the speakers and/or headphones? I am thinking the output sink is somehow not linked to the active sink. I had something similar because i am using an usb soundbar and i need to direct outputting apps to the active sink. –  Jun 02 '17 at 11:29
  • i use a Chrome and select webradio station to play music. Then open Output Settings gui to 'visualize' the ouput. That way i am sure of a constant audio supply so i can use pacmd to play with the settings. –  Jun 02 '17 at 11:39
  • Alex, please edit your question and paste the output of pacmd list-sinks. –  Jun 02 '17 at 14:43
  • @WillemK done. The manufacturer has indicated (via email) the output is listed as my HDMI, and needs to be switched to internal device. – alexwhitworth Jun 02 '17 at 20:21

This solved my problem:

pacmd set-card-profile 1 output:analog-stereo
