[17.04] Headphones sometimes work and sometimes don't work

Asked by David Bodow

My headphones don't work sometimes, but on reboot, they sometimes do. There is not any sound output. When plugging in the headphones, there is the usual quick burst of sound from plugging in any speakers; after that, there is no more sound. The problem has persisted throughout my installation of 17.04, but I haven't bothered troubleshooting it until recently. Right now, headphones are not working even after several reboots. I've tested the audio jack and headphones on my Windows partition, and the hardware is working just fine.

I've followed all of step 1 and step 2 from the Sound Troubleshooting Procedure: https://help.ubuntu.com/community/SoundTroubleshootingProcedure but haven't had any success. Submitting a question here is the start of Step 3, so I haven't progressed beyond that.

Here's my output from `alsa-info.sh`:

The problem is only for headphones; the integrated speakers work just fine.

I'm on a Lenovo P50, but can provide more hardware details if they're helpful.

Thanks!

Are you using a dock or just the system on its own

Make sure you have the latest BIOS as well.

(1) No dock, just the laptop's integrated jack.
(2) I'll update the UEFI when I get home from work tonight.

In the mean time, the computer has cycled back into producing sound through the audio this morning without any further changes from what I've described. Since this is a persistent problem (sound drops a few times a week for the full day or so and does not restore with reboots), do I need to wait until after it's out again to test the viability of any new solutions?

Thanks!

Can you help with this problem?
