Describe the bug
No hdmi audio after a recent upgrade. Setup is an LG tv into a sony dn1080. Rpi 4 with arch linux and kodi-rbp4 into dn1080 as well. Also, if the pi is on, the av receiver cannot use arc from tv, for example, when I'm using netflix from the TV. sudo /opt/vc/bin/tvservice -o makes ARC start to work immediately, but I have to reboot the pi to get the screen back tvservice -p does nothing.

My config is:

dtparam=audio=on
hdmi_drive=2
gpu_mem=512
dtoverlay=pi3-disable-bt
dtoverlay=pi3-disable-wifi
dtoverlay=vc4-fkms-v3d
hdmi_ignore_cec_init=1
initramfs initramfs-linux.img followkernel

I've played with multiple configs, changing resolutions, changing kodi output config from alsa to hdmi and back. nothing provided results. Including adding and removing hdmi_drive, hdmi_ignore_cec_init and hdmi_force_edid_audio.

To reproduce
Just boot with recent firmware. Currently using linux-firmware-20190815.07b925b-1-any and arch linux.

Expected behaviour
Audio is sent via hdmi to av receiver like it was about a month ago.

Actual behaviour
No audio via HDMI.

  • Which kernel version (uname -a)?
    already running the linux-raspberrypi4 kernel released these past days, but the issue started with the generic linux-raspberrypi kernel.

Linux rpi 4.19.68-1-ARCH #1 SMP PREEMPT Thu Aug 29 00:24:13 UTC 2019 armv7l GNU/Linux

Logs
The only thing weird in dmesg is this very threatening line (dmesg.txt):

snd_bcm2835: module is from the staging directory, the quality is unknown, you have been warned.

Possibly related to #3181.

No hdmi audio after a recent upgrade.

  1. Please identify the last known good firmware.
  2. Confirm that the headphone audio output still works.
  3. Reproducing the issue with Raspbian will lower the barrier for testing and increase the priority.
  4. Report it in the firmware repo, where it belongs.
