Dears,

We encountered a HDMI audio issue both on Freescale evaluation board SD board(iMX6Q) and our customized board for a long time.

 

The symptom is:

1) There is audio glitch after playing video or audio about 1hr.

2) But, it's strange. The issue will disappear after issue shown about 1hr.

*Test platform:

-SDB: u-boot/uImage/Ubuntu demo image got from v4.0.0/v4.1.0 image package

-customized board: u-boot/uImage built by LTIB and rootfs use ubuntu demo rootfs. (BSP source base are Linux v4.0.0/v4.1.0)

 

Can anyone give us any idea to debug it?

 

Thanks a lot
