Comment= # 7 on bug 92827<= /a> from Michael Zapf 
With 4.15 (and the kernel boot parameter!) I now managed to ge=
t audio output
via HDMI.=20

Splendid!

My configuration is=20

PC ----HDMI---> Pioneer AV receiver (vsx330) ---HDMI---> HP monitor (=
lp2475w)

But there is one bad effect now: When I turn off the monitor during runtime=
, or
if the monitor enters power-save state, and it is turned on again, the scre=
en
resolution is reset to a maximum of 1368x768 (before: 1920x1200), which mes=
ses
up the desktop.

The reason is that when the monitor is turned off, this seems to be sensed =
as a
change in the HMDI connection, and the EDID data is now coming from the AV
receiver.=20
