Hi,
I'm trying to run the latest mainline kernel 4.6 on the iMX6UL EVK. The board mostly works and the only problem is audio. Even though the sound card is detected and the ALSA mixer can be controlled there is no MCLK coming out of the SAI2 interface.
Also, have you tried setting bit 20 (SAI2_MCLK_DIR) of register IOMUXC_GPR_GPR1?
You can set this bit in the bootloader for a quick test.
