--- Comment #10 from senoladem at hotmail.com ---
My previous comment was missing dmesg:

With kernel 4.4:

dmesg for non-working sound (booted my device (server/htpc) first, then my tv,
as described in my previous post):
senol at masterserver:~$ sudo dmesg | pastebinit
http://paste.ubuntu.com/23759278/

dmesg for working sound (booted my device while the tv is turned on):
senol at masterserver:~$ sudo dmesg | pastebinit
http://paste.ubuntu.com/23759293/


I also installed 4.8.1-040801 for testing. The behaviour is still the same.

dmesg for non-working sound:
senol at masterserver:~$ sudo dmesg | pastebinit
http://paste.ubuntu.com/23760114/

dmesg for working sound:
senol at masterserver:~$ sudo dmesg | pastebinit
http://paste.ubuntu.com/23760097/


I double checked my edid whether it is correct, and it is (audio information
present, 256 bytes long). The dmesg shows that I have my edid emulation up and
running. This has to be a bug with the sound driver for intel.
