No sound through audio jack (16.04 Xenial)

Asked by Dalton Wu

I am dual-booting a fresh install of Ubuntu 16.04 LTS and Windows 10 with the anniversary update on an Asus K55A laptop (separate mic and headphone jack, two jacks total). In Windows, both the speakers and headphone jack work. In Ubuntu, only the speakers do. I do not know if the HDMI audio works or not and cannot test that at this time.

I have followed steps 1 through 8 at https://help.ubuntu.com/community/SoundTroubleshootingProcedure but none have been effective.

Step 3 output: http://www.alsa-project.org/db/?f=df6d8084ba87e6b7ecd2e5aa6a3f4f155a463d57

Terminal output for steps 3 and 4:

Please try this solution:

https://answers.launchpad.net/ubuntu/+source/alsa-driver/+question/291874

Make sure to increase volume to 100% on all mixer channels in alsamixer (Terminal application)

Test all audio jacks at the front and the back of your PC.

Hello Mark,

Thanks so much for your quick response! My problem is now solved, but I don't know for sure how! Let me explain, for posterity:

After asking my question, I let my computer sleep for three hours without doing anything more. I then took a look at the link you posted, but, before I followed anything on that page, I opened alsamixer and turned up all the bars. The strange thing is, I already did this yesterday and again today, so Master, <Headphones>, PCM, and Speaker were all already at 100 -- but I wiggled them down and up, and moved the bars for Mic and Mic Boost up to 100 this time.

Concurrently, I opened an MP3, which Ubuntu decided to use Videos to open (I guess because there was album art!). Then Ubuntu asked to download some things for MP3 support, which I allowed. Could this have anything to do with my problem being solved???????

Anyway, the MP3 magically began playing through my headphones. I had not restarted, shut down, or even logged out! To figure out what made the magic happen, I went back to alsamixer and set the Mic and Mic Boost back down to 0 -- no effect. I changed the alsamixer sound device back to default using F6 (which I previously did in an attempt to fix the problem) -- no effect. Very confused, but I'll take it ...

Not sure if I should _mark_ your solution as the solution.

EDIT: I restarted while writing this message ... and the problem is back. Will reply with more information later.

Update:

I tried the alsamixer fix again -- no effect. Then I tried the solution Mark linked to and restarted. Success!

No idea why the bug temporarily disappeared when I played the MP3.

Thanks Mark Rijckenberg, that solved my question.
