video bios
I'm using debian stretch on a Shuttle SG33 system (Intel G33 Chipset).
With debian kernel 4.9.0-8-amd64, the two output ports are correctly discovered
: one HDMI and one VGA:
$ ls /sys/class/drm/
card0 card0-HDMI-A-1 card0-VGA-1 controlD64 renderD128 version
With debian kernel 4.18.0 (from stretch-backports), the HDMI port is discovered
as DVI port, and the audio output no longer works on this port:
$ ls /sys/class/drm/
card0 card0-DVI-D-1 card0-VGA-1 renderD128 version
My "main" issue is the missing audio on the HDMI port when it is detected as
DVI. The video is working properly.
I'm attaching the video bios, but I don't know it it is relevant, I can provide
more information if needed.</pre>
