[Georg Schmitz <1276901@xxxxxxxxxxxxxxxxxx>]

Chris (c.hudec@xxxxxx) created a fix.
It's not working 100% and sometimes sound crashes or it contains "vibrations", but the basics work!

Here is his message from the mailing-list:
Hey

Here is my attempt to get sound working at hammerhead.

The files are not final and i haven't tested everything, but they should
be fine to get speaker, headphones and sound during calls working.

Unpack the attached archive and copy the folder to "/usr/share/alsa/ucm/".
Would be great if someone could test them and give me feedback.

Best Regards,
Chris

Title:
  alsa-lib: UCM - hammerhead sound doesn't work

Status in “alsa-lib” package in Ubuntu:
  Confirmed
Status in “android” package in Ubuntu:
  Invalid

Bug description:
  1.) The release I'm using:
  Description:	Ubuntu Trusty Tahr (development branch)
  Release:	14.04
  2.) Paket pkgname kann nicht gefunden werden (package pkgname could not be found)
  3.) What I expected to happen:
  Sound should have worked on hammerhead ootb or after performing the steps below (according to the porting guide)
  4.) No sound at all

  The correct sound driver was not used, so I performed the following
  steps:

  1.) Checked '/proc/asound/cars' so see which sound card is installed
  2.) Created the path '/usr/share/alsa/ucm/msm8974-taiko-mtp-snd-card'
  3.) Copied the three files from
  '/usr/share/alsa/ucm/apq8064-tabla-snd-card/'
  to
  '/usr/share/alsa/ucm/msm8974-taiko-mtp-snd-card'
  4.) Renamed
  'apq8064-tabla-snd-card.conf'
  to
  'msm8974-taiko-mtp-snd-card.conf'
  5.) Modified the files 'HiFi' and 'VoiceCall'. Find&replaced
  'apq8064tablasnd'
  with
  'msm8974taikomtpsnd'

  I attached dmesg, logcat, syslog, amixer and alsa-info before I made
  the changes (folder original) and after (folder modification).

  Thank you for helping to fix.

  Georg
