pipeline_passthru example / 2 channel mic problem

Postby benbiles » Sun Dec 15, 2019 4:58 pm

Hi,

I have flashed pipeline_passthru example on lyrat v4.3 and stereo line input asses through in stereo to headphones as expected.

I changed

AUDIO_HAL_CODEC_MODE_LINE_IN

to..

audio_hal_ctrl_codec(board_handle->audio_hal, AUDIO_HAL_CODEC_MODE_BOTH, AUDIO_HAL_CTRL_START);

Now I get one mic channel at approx half the level on L&R headphones

The other mic only comes out of one headphone channel and is twice as load.

Is there something else i need to change ? or can it be a hardware problem ?

maybe someone else can try it and tell me if they get the same ?

Any ideas would be much appreciated.
