Simultaneous Audio Capture & Playback in IMX6

himanshugusain — Fri, 28 Jul 2017 05:20:35 GMT

We have 2 different sound cards configured Audio Codec & BT SCO

We are working on the usecase where we record from Bluetooth interface & simultaneously sends that data out

through Audio Codec (external speaker).

How can we verify this functionality from the avaliable command line utility like tinycap & tinyplay .

Or Is there any command line utility which can be used to test this functionality

Hi himanshu

for basic codec testing one can try unit tests (folder /mxc_sound_test)

and dscription in attached Linux Manual sect.28.5 Unit Test
