Hey

I've updated my first version a bit, so here is v2.
Changed some values to match the hammerhead file Georg sent to the mailing list yesterday.
I can't really reproduce the "distortion" in sound, except when you plug in headphones (the first thing played is distorted).

There is also a bug, that when you plug in and out headphones after a call the sound is gone system wide.
Maybe someone can help out here (see attached syslog).

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
