HI All ,
I am working on bluetooth sco data over PCM at IMX6dl based custom HW with android 4.4.3 and I can record audio by using “tinycap” and played it back on BT headset via “tinyplay” , which sound good.
But I get the problem when I tried to play some other * .wav file(which is not recorded from BT headset.) via tinyplay. all those file sound like faster or someting noise, So I have a question about sco over pcm.
Does PCM data transferred over PCM bus, need to be SBC encoded if the pcm interface connected with Bluetooth module ?
