HardWare: IMX8QM MEK B0
Android Version: Android P (imx-p9.0.0_2.1.1-auto-ga-android_build)
Kernel Version :4.14.98
Play audio using tinyplay and record audio using tinycap, The command is
It's normal when played and recorded separately. But start recording while playing audio, the audio file 123.wav has no any voice.
I replace tinycat with android system app of SoundRecorder recording audio, It's the same effect.
Does wm8960 support simultaneous recording and playback? Or does the Sai interface need to be configured in full duplex mode?
Dose anyone have this problem on imx8 or other platform ?
Please give guidance to solve the problem, Thanks!
