Hi,
I've tried to test HDMI Audio hot plug detection on imx6 board. I'm using mainline-4.14 kernel version & DRM subsystem (drivers/gpu/drm/bridge/synopsys/dw-hdmi-ahb-audio.c)
I've verified following two cases
case a:
- boot target
- connect cable
- play back (No Sound)
case b:
- boot target
- play back
- connect cable (No sound )
Both, case a & case b are failing only working case is case c,
case c:
- boot target
- play back (Can Hear sound)
- disconnect cable
- connect it back (Can hear sound)
Is this known issue?
