How to enable sgtl5000 in android kitkat with imx6q?

[conteczxy]

Hi, I am porting sgtl5000 drivers to android 4.4.2, and there is still no sound, and when selecting from Setting->Sound->notification sound menu, some error shows in logcat,

log as below:

---------

11-24 18:06:23.900: E/MediaPlayer(2957): Error (-19,0)

Some days ago,  I made similar porting steps in android4.3, it works well, but it is not applicable to android4.4.

Where is the problem?  Any suggestion is appreciated.

Thanks.

I found config_sgtl5000.h was missing in the dir "hardware/imx/alsa",

and tinyalsa_hal.c should be made some changes.

-------

#include "config_sgtl5000.h"

... ...

struct audio_card *audio_card_list[SUPPORT_CARD_NUM] = {

   &sgtl5000_card,

    &wm8958_card,

    &wm8962_card,

    &hdmi_card,

    &usbaudio_card,

    &spdif_card,

    &null_card,

};
