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
02-12 02:33:32.440 207 7177 W APM::AudioPolicyManager: getOutput() could not find output for stream 1, samplingRate 48000,format 1, channels 3, flags 4

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
