I also can confirm, sound is not working on hammerhead. Digging around a bit I did notice that the soundcard is being recognized at least, so maybe it's a config problem? I also seen that alsa is not starting the audio mixer.. This is my first attempt at porting so I hope the info I just provided is useful.

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).
