No sound from brand new System76 laptop Ubuntu 18.04 speakers

Asked by David Taylor on 2019-03-12

I'm afraid I foolishly tried other solutions probably more suited to earlier versions of Ubuntu before I discovered this. For example, I added a line in some .conf file somewhere in /etc and got sound, but only until the next reboot. I also removed and reinstalled also and pulseaudio and force-reloaded alsa; when I restarted, I got some hiss from my speakers during the restart process, but no sound.

I think before I did that last step when I tried to test the speakers in the Sound settings under Speakers - Built-in Audio the little speaker icons at least turned blue, and produced no sound, but they certainly do not turn blue now.

Here is the output created by Step 3 of https://help.ubuntu.com/community/SoundTroubleshootingProcedure:

It's 18.04, not 18.10

David Taylor (prooffreader) said : #2

Apologies, you are correct, I misremembered. I've only had this thing a few days. I'm glad it came with a LTS distro.

David Taylor (prooffreader) said : #3

I've changed the title of the question to reflect that this is Ubuntu 18.04 LTS, not 18.10 as it previously stated.

Do you get sound in headphones?

David Taylor (prooffreader) said : #5

No, when I plug in headphones, the entry "Speaker - Built-In Audio" in Settings > Sound changes to "Headphones - Built-In Audio" but otherwise there is no change

If you run:

alsamixer

Are all levels maxed and unmuted. Use ESC to exit, M to un/mute and cursor keys as you expect. Use F6 to change the device manipulated.

David Taylor (prooffreader) said : #7

In alsamixer, all levels are indeed maxed (at 100/+0.0 dB and showing red on top of the bar) and unmuted (showing 00 instead of MM) for both sound devices (only the S/PDIF devices remain when I select the NVIDIA sound card, Master and Speakers appear when I select HDA Intel PCH sound card).

https://support.system76.com/articles/upgrade-ubuntu/

They seem to have their own PPA with drives and such....

Worth a punt

David Taylor (prooffreader) said : #9

That action did not change anything.

David Taylor (prooffreader) said : #10

I have had two support tickets with System76. When I briefly had sound by editing a .conf file before a restart, I closed the first. I have had no answer yet to the second.

David Taylor (prooffreader) said : #11

adding

options snd-hda-intel model=generic

to the end of

/etc/modprobe.d/alsa-base.conf

briefly fixed my problem, but upon restart the problem was back.

I just checked that file, the final line I added was gone, I put it back, but still no sound.

David Taylor (prooffreader) said : #12

WIth help from System 76, sound has re-appeared. Thanks for your help!

What was the magic bullet, please. It may help others

David Taylor (prooffreader) said : #14

Literally as simple as restarting two or three times. This was after I added that line to /etc/modprob,d/alsa-base-conf as described above, I have no idea if that made a difference.

Interestingly, though, I can't TEST the sound in the control panel (nothing happens). But otherwise sounds play.
