Evnin'

used so far the latest git build from openelec as it supports hdmi audio on the minix neo z64 platform...

Now with libreelec git build from today there is no more hdmi audio..and in the boot message I se this message which I don't have on openelec:

[    7.845931] had: snd_intelhad_open: HDMI cable plugged-out

Have you done what lrusak told you?

Yes...installed this tar file and rebooted...

Is that an official git branch?

The working openelec git build shows:

Seems those file changes from openelec-8 are causing the problem as they are different:

Code

drivers/gpu/drm/i915/intel_hdmi.c
drivers/gpu/drm/i915/i915_reg.h
drivers/gpu/drm/i915/intel_drv.h
drivers/gpu/drm/i915/i915_irq.c
