Hello,
BSP:IMX8 MINI EVK
Linux imx8mmevk 4.14.78-imx_4.14.78_1.0.0_ga+g21fc82c
I am using IMX8 Mini EVK (yocto)and I try to play music using Bluetooth A2DP.
So far, I am able to pair and connect to my phone.
When the phone plays music, Imx8 Mini does not have any audio output
How can i modify?
You can refer the below link to set the default source as a bluetooth and audio jack (on which the loudspeaker was connected) as a default sound card.
