No audio on IMX6DL-SDP with android jb 4.3 and 4.2

Question asked by CMarco on Feb 20, 2014

Hi community,


    we are having problems with audio on our SABRE SD Plaform EVB (IMX6DL-SDP) using prebuilt images for android JB 4.3 (jb4.3_1.1.0-ga) and JB 4.2.2 (jb4.2.2_1.1.0-ga).

Actually no audio is emitted by the speakers nor the headphones. The same goes for "system sounds", sound files (16 bit PCM wav using both OMXPlayer and the "tinyplay" command line application) or sound tracks included in video files.

The audio capture is not working too. The AudioCapture app keeps crashing.


By using the android 13.4.1 prebuilt images audio is correctly working (play and record).


In the attached archive:

- dmesg_jb4.3.txt : dmesg output;

- logcat_jb4.3.txt: logcat output during an audio file play with OMXPlayer. Note that the "W/AudioTrack( 2356): obtainBuffer timed out" messages start before launching the player;

- logcat_audiorec.txt: logcat output during audio record


Thanks and regards
