R9 285 Tonga with DC (only DC ever worked for HDMI audio with = this card/TV combo) Haven't tested any other use cases other than mine =3D=20 HDMI TV is off DVI-D monitor is on with X running, Turn on TV, do=20 xrandr --output HDMI-A-0 --auto && xrandr --output HDMI-A-0 --below= DVI-D-0 Since this commit I get no sound. commit cfb071f7a9673109415d097125b3c12c16836acc Author: Charlene Liu <charle= ne.liu@amd.com> Date: Wed Nov 15 18:55:57 2017 -0500 drm/amd/display: try to find matching audio inst for enc inst first [Description] in eDP+ HDMI/DP clone or extended configuration, audio inst changed from inst 1 to inst0. No failure related this though, just playback device endpoint inst chan= ged. Also remove one addition register read.
Bump! Still broken on latest drm-next-4.17-wip. Tried booting with both screens on, no better.

This issue is related to AFMT_CNTL's AFMT_AUDIO_CLOCK_EN. sequ= ence issue. fixed.
Thanks, I'll close when the fix makes it into something public. Current agd5f drm-next-4.18-wip still has the issue.
What is the fix? I see drm/amd/display: HDMI has no sound after Panel power off/on just went in agd5f drm-next-4.17 But this does not fix this issue.

dmesg with hdmi warnings
Hmm, maybe something else is going wrong.
I am getting hdmi warnings in dmesg (attached) when enabling the TV - I hav=
en't
seen these before when testing this issue.
It seems that HDMI has no sound after Panel power off/on is the cause of the warnings. I tested 4.18-wip, no sound of course but nothing in dmesg. I then applied "HDMI has no sound after Panel power off/on" as a = patch and get no sound + the warnings in dmesg on enabling the TV. Remove the patch, then=20 git revert cfb071f7a9673109415d097125b3c12c16836acc=20 =3D working sound.

There were a couple of fixes wrt HDMI audio in DC v3.1.47. The= y've been merged today to https://cgit.freedesktop.org/~agd5f/linux/log/?h=3Damd-st= aging-drm-next
I tried agd5f drm-next-4.19-wip, which reports [drm] Display Core initialized with v3.1.47 but still no sound. The warning/bt in dmesg is not there any more.
I have a new TV now and can't get hdmi audio working at all. Maybe my use/setup of alsa doesn't help, but IIRC I did try and fail with a fedora live USB as well. It works perfectly if I boot into Windows 7, so I know this TV/card combo is OK.
