Public bug reported: I updated my Surface Pro 3 From Ubuntu 17.10 to Ubuntu 18.04 (did a clean install) and the only audio working was from the headphone jack. I tried all these: [troubleshooting guide](https://help.ubuntu.com/community/SoundTroubleshootingProcedure) [this answer](https://askubuntu.com/questions/117842/no-sound-from-speakers-but-headphones-work) [another answer](https://askubuntu.com/questions/829520/ubuntu-16-04-no-sound-from-speakers-only-headphones-working)
I went back and tested the live CD and even the live cd has no audio through the speakers. so this must be related to 18.04. I never had sound issues before and under windows audio still works correctly. here is my alsa iformation http://www.alsa- project.org/db/?f=8bf135db52610a603014779ef24041a491c8a32d and here is how I fixed it: renaming /etc/modprobe.d/alsa-base.conf to /etc/modprobe.d/alsa-base.bk , then rebooting the computer fixed the my speaker sound issue. I then restored line by line in to /etc/modprobe.d/alsa-base.conf, rebooting between restored lines, until all lines were back.... and ... it still worked! so I restored the original /etc/modprobe.d/alsa-base.conf and rebooted the computer and everything was still working.... so I am not sure what the problem was but is now fixed.
