The i2c bus on imx6qdl-wandboard has intermittent issues where SDA can freeze on low level at the end of transaction so the bus can no longer work. This impacts reading of EDID data leading to incorrect TV resolution and no audio. This scenario is improved by adding scl/sda gpios definitions to implement the i2c bus recovery mechanism.
