Hi,
After connecting i2s0 to external codec for audio capture, 2 channel capture works but when I try to capture multichannel audio(4 or 8) . Tinycap gives error as follows:
./tinycap test.wav -D 0 -d 1 -r 16000 -b 16 -c 4
Unable to open PCM device (cannot set hw params: Invalid argument)
Captured 0 frames
Can someone tell me if 8 channel capture is supported on hikey ?If it is supported then how to capture multichannel audio on i2s0 and What changes needs to be done (e.g HAL,i2s driver)?
Regards,
Moin
