No HDMI Audio on PI 4 after update

Postby tiagoboldt » Thu Aug 15, 2019 10:01 pm

So, after the kodi for pi4 build, everything was working fine on my pi4, including 4k video. Last week or so an update killed my audio. I've tried setting HDMI out and alsa in kodi configs. I've tried the whole /boot/config.txt combinations, even with `hdmi_drive=2`.

Also, very important. After the same update, for some reason, the raspberry pi is DoS my Sony DN1080 amp. It stops detecting ARC from the TV. If I unplug the pi HDMI cable and plug it back again, ARC works again.

I'm running an up to date system. Suggestions?

My current boot config is:
dtparam=audio=on
avoid_warnings=1
gpu_mem=512
boot_delay=1
dtoverlay=pi3-disable-bt
dtoverlay=pi3-disable-wifi
dtoverlay=vc4-fkms-v3d


Note: shutting down hdmi with `sudo /opt/vc/bin/tvservice -o` makes ARC work again, but getting it back with `tvservice -p` keeps the screen black, kodi doesn't come back on.

There are other reporting the same problem elsewhere: https://www.raspberrypi.org/forums/viewtopic.php?t=248094
I've been playing with hdmi_force_edid_audio=-1 and a bunch of other options to no success. I'm not being able to isolate this as a kernel, alsa or kodi issue.
