Raspberry 4: audio and video on different HDMI-ports not working

Frank_Foerster · August 26, 2023, 7:36am

Hello,
I’m the new guy, starting with a problem!
I’m currently building an Audio Streamer using a Raspberry 4b 4GB and Volumio. The streamer should be connected via HDMI to the AVR. On the second HDMI, there should be a Display.

There are two possibilities for audio and video-routing, both are not working properly.
Variant 1:
HDMI0 > AVR= sound is playing
HDMI1 > Display= no video (Display is powered up via USB and “glowing”)

Variant 2:
HDMI0 > Display= video is on
HDMI1 > AVR= no sound

I tried several entrys in the config.txt and even in the cmdline.txt, with no sucess.

This is my actual config.txt:

initramfs volumio.initrd
gpu_mem=32
max_usb_current=1
dtparam=audio=on
audio_pwm_mode=2
dtparam=i2c_arm=on
disable_splash=1
hdmi_force_hotplug=1
force_eeprom_read=0
hdmi_drive=2

include userconfig.txt

And this is the userconfig.txt:

Add your custom config.txt options to this file, which will be preserved during updates

hdmi_group=2
hdmi_mode=87
hdmi_timings=400 0 100 10 140 1280 10 20 20 2 0 0 0 60 0 43000000 3
hdmi_blanking=1
max_framebuffers=2

Touch Display rotation setting below: do not alter ####
display_lcd_rotate=3
display_hdmi_rotate=3

What can I do to get both audio and video working?
I tried Raspberry OS, there are both HDMI ports working properly.

@gvolt can you take a look at this?

Frank_Foerster · August 27, 2023, 10:21am

So… I tried Raspberry OS. On both HDMI ports, I get Sound and Video. I think, it is a Volumio issue.
Question:
What do I have to do to get it running with volumio?

dvo · August 27, 2023, 2:05pm

you have to wait till @gvolt can take a look.for you.
trying a other OS says nothing about Volumio every screen needs different settings.

gvolt · August 28, 2023, 8:04am

When using Variant 1 you could try adding

framebuffer_priority=7

to “/boot/userconfig.txt”.

Frank_Foerster · August 28, 2023, 11:22am

It doesn’t help. Still no video on 2nd HDMI.
I tried it with the actual OS and a new installed OS. Both didn’t work.

gvolt · August 28, 2023, 11:39am

Is it the same without the AVR being connected to HDMI0?

Please post the output of

ls -al /dev/fb*

cat /var/log/Xorg.0.log

Frank_Foerster · August 28, 2023, 12:22pm

This is with AVR connected to HDMI0:

Without AVR and Display connected to HDMI1, I had to start without the display, otherwise Wlan wouldn’t come up.

Please check if adding the HDMI port’s index helps (not really expecting it, but…):

hdmi_group:1=2
hdmi_mode:1=87
hdmi_timings:1=400 0 100 10 140 1280 10 20 20 2 0 0 0 60 0 43000000 3
hdmi_blanking:1=1

Frank_Foerster · August 28, 2023, 7:52pm

It works!
@gvolt: You, Sir, are my hero!
This is now the code in the userconfig.txt (maybe I delete the out commented lines and clean up a bit):

# Add your custom config.txt options to this file, which will be preserved during updates

hdmi_group:1=2
hdmi_mode:1=87
hdmi_group:2=2
hdmi_mode:2=87
hdmi_timings:1=400 0 100 10 140 1280 10 20 20 2 0 0 0 60 0 43000000 3
hdmi_blanking:2=1
hdmi_timings:2=400 0 100 10 140 1280 10 20 20 2 0 0 0 60 0 43000000 3
hdmi_blanking:2=1

#hdmi_group=2
#hdmi_mode=87
#hdmi_timings=400 0 100 10 140 1280 10 20 20 2 0 0 0 60 0 43000000 3
#hdmi_blanking=1
framebuffer_priority=7
max_framebuffers=2

#### Touch Display rotation setting below: do not alter ####
display_lcd_rotate=3
display_hdmi_rotate=3

Works like a charme!

gvolt · August 28, 2023, 8:11pm

But what makes me wonder is that, to my knowledge, only “:0” is valid for the first HDMI port (labeled “0”) and “:1” is valid for the second HDMI port (labeled “0”). So I would think that the HDMI index “:2” should have no effect. Did you also test without the “hdmi_…:2” entries?

Frank_Foerster · August 28, 2023, 8:14pm

Hmm, you are right, I use 1 and 2 instead of 0 and 1…
I’ll try it tomorrow and let you know.

Frank_Foerster · August 29, 2023, 7:17am

Good morning, everybody!

So, I tried booting with out commented HDMI2, and it works perfect. Then I tried booting additionally with out commented

framebuffer_priority=7

and Volumio didn’t start completely (Stops at the point where the lettering “Volumio” pops up, several times).
So, this is my actual, working userconfig.txt:

# Add your custom config.txt options to this file, which will be preserved during updates

hdmi_group:1=2
hdmi_mode:1=87
hdmi_timings:1=400 0 100 10 140 1280 10 20 20 2 0 0 0 60 0 43000000 3
hdmi_blanking:1=1

framebuffer_priority=7
max_framebuffers=2


#### Touch Display rotation setting below: do not alter ####
display_lcd_rotate=3
display_hdmi_rotate=3

Puh, case closed…next step will be implementing a working power On/Off-Button.
Thanks again!
