Hi NXP

Thanks your feedback.

My imx6q platform OS is android 6.0.1. We need the android 6.0.1 solution.

My customer need to change "sample rate" for play and record.

So do you have any solution about change the sample rate in Android 6.0.1.

I try get some log message and when I  open Audio APK.

logcat -v time | grep audio

06-23 10:21:43.842 W/audio_hw_primary(  212): do_out_standby... -1242503424
06-23 10:21:49.552 W/audio_hw_primary(  212): out_set_parameters routing=2, ret 0, out -1242503424

The some message form hardware/imx/alsa/tinyalsa_hal.c . (not linux kernel.)

Do you have any advice?
