We can’t manage to get sound working over HDMI, on Up2 Squared board.
We use a x64 resin Debian stretch image.
On Resin OS 2.12.7+rev1, “HDA Intel PCH” appears as a card, but has 0 playback device.
We also tried to flash Resin OS 2.13.3+rev1, since this release fixes audio over HDMI (https://github.com/resin-os/resin-up-board/issues/51).
But even “HDA Intel PCH” does not appear, and we don’t have any sound over HDMI.
Do you guys have any ideas why?
Thanks in advance
