Thank you for taking the time to report this bug and helping to make Ubuntu better.

How far did you get in troubleshooting sound? ie. did you attempt to follow https://help.ubuntu.com/community/SoundTroubleshootingProcedure or another wiki site?

I believe a Support site would be more appropriate, eg. https://answers.launchpad.net/ubuntu . You can also find help with your problem in the support forum of your local Ubuntu community http://loco.ubuntu.com/ or asking at https://askubuntu.com or https://ubuntuforums.org.

I can see no crash info, no issues with detecting your hardware, and "No sound" isn't very helpful in knowing what you've attempted to do in order to get sound working. I'm going to mark this 'incomplete' and suggest you go to a support site; if you feel I'm in error, please provide more detail and change it to 'New"

If you plug sth in the Red lineout rear, does the UI detect your plugging (gnome-sound-setting).

When the Red lineout rear jack is plugged sth, please run "sudo hdajacksensetest -c 1 -a", and upload the output.

Does the rest 3 lineout jacks (maybe black color jacks) work well?
