Android6.0 audio cause touch lag

[yenchou]

Hello All,

   kernel:Linux4.1.15

   OS:Android6.0   

   machine:imx6dl(custom board)

   Because our custom board dose not have audio chip,it caused touch lag.

logcat:

02-12 02:33:32.435 207 7177 W APM::AudioPolicyManager: getOutput() could not find output for stream 1, samplingRate 0,format 0, channels 3, flags 0
02-12 02:33:32.436 207 207 W APM::AudioPolicyManager: getOutput() could not find output for stream 1, samplingRate 0,format 0, channels 3, flags 0

I want to close audio function.

I try to close driver,jni and framwork of files about audio,but some behaviours could lead build error.

I try to serach goole and freescale forum,but it did not have solution.

How can I slove the problem?

Best Wishes

Hello Yen,

   See my advice for you below, please!

   SPDIF audio is supported by i.MX6, you can add it's driver in linux kernel. Then android audio interface will not show those errors.

try it, please!

Have a nice day!
