[Bug 1512129] Re: Headphones not detected at startup

 

Further investigation - this seems to be because I am running with a
separate /var partition and the alsa systemd services are being started
before the /var partition is mounted.

I have tried altering my fstab to include the x-initrd.mount option as
suggested at http://superuser.com/a/841748 on the /var partition (so the
options end up being defaults,x-initrd.mount) but this appears to
prevent the partition from being loaded altogether. Searching for this
brought up a Red Hat bug:
https://bugzilla.redhat.com/show_bug.cgi?id=1249513 - not sure if
Kubuntu 15.10 would be affected by that?

Title:
  Headphones not detected at startup

Status in alsa-utils package in Ubuntu:
  New
Status in kubuntu-meta package in Ubuntu:
  New

Bug description:
  The headphones are not detected if they are plugged in before the
  system starts up. To get sound out of my headphones, I need to unplug
  the headphones and plug them back in again. After this, sound is sent
  to the headphones.

  Reproducible: always

  Steps to reproduce:
  1. Plug in headphones
  2. Switch on computer, log into Kubuntu
  3. Attempt to play sound in any application, no sound produced.
  4. Unplug and replug headphones
  5. Sound works

  Expected behaviour:
  At step 3, sound should be output through the headphones.

  The problem seems to be in alsamixer: when starting Kubuntu the
  headphone volume is set to zero and the headphones are muted. Re-
  plugging the headphones will unmute the headphones in alsamixer and
  set to an audible volume.
