I installed Ubuntu 14.04 on a computer with a Gigabyte GA-990FXA-UD3 (rev 1.0) motherboard. This motherboard has a Realtek ALC889 "HD Audio" chip. However, the volume control only shows "Dummy Output" and I do not hear any sound.

When I run lspci, the output includes the following line:

00:14.2 Audio device: Advanced Micro Devices, Inc. [AMD/ATI] SBx00 Azalia (Intel HDA) (rev 40)

When I run find /lib/modules/`uname -r` | grep snd, I see lines for a number of codecs, including /lib/modules/3.13.0-29-generic/kernel/sound/pci/hda/snd-hda-codec-realtek.ko, which I would have thought is the correct one. modprobe -c | grep realtek shows that this codec is loaded.

I was going to try installing the generic Realtek HD Audio driver, but I don't want to mess things up if there's a better way.

If it matters, I am using XFCE instead of Unity.

  • Perhaps this will help http://www.unixmen.com/2012003-howto-resolve-nosound-problem-on-ubuntu/ – TuKsn Jun 18 '14 at 21:08
  • @Tuknutx thanks, but that doesn't help. In step 1, the only audio output device listed is "Dummy Output" so there's no help in adjusting the volume. In step 2, I get cannot open mixer: No such file or directory. In step 3, I get Unloading ALSA sound driver modules: (none loaded). Loading ALSA sound driver modules: (none to reload). Step 4 says that it is not compatible with 14.04. – Moshe Katz Jun 19 '14 at 16:47

I found that trying to run aplay -l (as suggested in other places) returns the following message: aplay: device_list:268: no soundcards found...

A Google search for that text found this answer which solved my problem.

sudo modprobe snd-hda-intel
