How to enable audio on audio jack ?

Hi ,

We have custom imx6 board running with Android Jellybean. But audio is not working on 3.5mm audio jack, it only works on HDMI. according to Audio | Android Open Source Project this site all files are at proper places except i did not find any file mentioned as

hardware/libhardware/include/hardware/audio.h

. So i checked Android source given by Freescale for sabre board for smart devices & there also i did not find that file but audio jack works there on that board. So where is this file exactly? Also my boot log shows :

<6>ALSA device list:
<6> #0: Dummy 1
<6> #1: imx-hdmi-soc

why only imx-hdmi ?? Can anyone tell me where i should look exactly to get audio jack working ? What all drivers/libraries i need to compile ? Can you please tell me their locations in the source ?

Hi Amit,

Which Audio codec you are using with custom hardware?

You need to add driver for your codec.

Thanks

Thank you Saurabh for your reply.

The Audio CODEC used on the Board is ALC5610 from Realtek. Do i need any kernel configurations for this codec ?

Following two Realtek driver supported in Linux kernel.

./soc/codecs/alc5623.c

./soc/codecs/alc5632.c

You need to modified this driver.

Also code modification depends upon the interface used with i.MX6.

Thanks
