Hi, our product is using base on SDK_3.0.35-4.1.0_GA, audio codec is the same as i.mx6Q SabrdSD board(wm8962 but without PMIC)
Recently, our customer complain about our i.mx6Q product sometimes can't play or record sound.
and I only got one line error message: "wm8962 0-001a: DC servo timed out"
When this issue happen, aplay or arecord will just stuck, 'till press ctrl+c to interrupt the paly/record process.
and after the interruption done, aplay/arecord once again working fine.
I search the entire community about keyword "wm8962", and found nothing useful. could some one give me a hint or suggestion what I should check?
p.s: in order to using alsamixer, there is a /etc/asound.conf:
/********************************************************************/
