Audio driver Dragonboard 410c, yocto


#1

Hi, I get the dreaded “no sound card found” on Yocto

Yocto, Poky, Rocko branch. Have tried the core-image-sato and linaro-image-alip. Everything I try produces the same results.

On boot this message comes up:

[ 1.778255] ALSA device list:
[ 1.778257] No soundcards found.

after a while, lots of these pop up:

qcom-apq8016-sbc 7702000.sound: error getting codec dai name

Suggestions welcomed!
