Installed Ubuntu 17.10 fresh from a DVD and cannot get the sound to work. Ran lspci -v and got the following:

The device in the manager shows as: Digital Output (S/PDIF) - Built-in Audio Profile: Digital Stereo (IEC958) Output

I noticed that in past installs of Ubuntu, (12, 14, and 16) I noticed the sound device would be an analog device. I noticed once I updated the system, if it went to digital as shown above, the sound dies and I cannot recover.

I've installed PulseAudio, which did not help.

Anyone have any suggestions?

  • I have had so many problems with sound. I have a different version than you but the steps I use to get output working again should also apply to you since they’re just from the Ubuntu Help Wiki sound troubleshooting procedure. I just cycle through the following: 1) executing the first two commands in step 1A, 2) opening pavucontrol from Terminal and adjusting the sliders even if they seem to be at 100% already 3) opening Settings>Sound and doing the same 4) opening alsamixer 5) repeating all steps if sound isn’t back – Hee Jin Apr 27 '18 at 0:49
  • I know it’s kinda dumb and clunky, but I have tried a lot of different things and nothing worked. I also filed a bug since I had a fresh installation and all my sound related hardware etc was supposedly supported by my kernel version. No one could offer a better more permanent or even more specific fix. – Hee Jin Apr 27 '18 at 0:51
  • Also I’ve read that the versions of Firefox that come with 17.10 and 16.xx can cause problems with sound. Sorry I can’t be more specific but I have long since ditched Fireox because it also constantly crashes on me even with cache relocated to RAM – Hee Jin Apr 27 '18 at 0:54
  • Thanks Emily. I doubt if those steps will work as I've tried them in the past with older versions of Ubuntu and I've always fell flat on my face. But it doesn't hurt to try. Thanks again! – Howard Huie Apr 27 '18 at 15:36
  • No problem. Again, sorry I didn't have anything better for you. One thing I just realized that maybe you want to check is under the Configuration tab in pavucontrol there is a profile option where you can select Analog (instead of Digital). Have you looked there? – Hee Jin Apr 27 '18 at 15:43
