Can not use the composite output in recalbox 7.2.2 on my Raspberry pi 4b

[edwinsources]

I have read several posts on how to configure the composite video outputs through the jack port using the correct cable without any success. Edit the config.txt and recalbox.config.txt and get it to render image but freezes on pacman 3 ghosts image. Someone who can help me please

These are all the codes I tested in different combinations:

Hdmi_force_hotplug=0
Hadmi_force_hotplug=1
hdmi_ignore_hotplug=0
hdmi_ignore_hotplug=1
#hdmi_safe=0
enable_tvout=1
sdtv_mode=0
hdmi_ignore_hotplug=1
audio_pwm_mode=2
sdtv_aspect=1
global.videomode=default

It only gives me image using with these lines

Enable_tvout=1 and Changing dtoverlay=vc4-kms-v3d-pi4 by (dtoverlay=vc4-fkms-v3d-pi4)

@edwinsources First, please don't SPAM:

• https://forum.recalbox.com/topic/25247/no-logro-usar-la-salida-de-video-compuesto-en-recalbox-7-2-2-en-mi-raspberry-pi-4b

I was forced to lock the above two topics because we don't need a polluted forum with the same question from the same user - That kind of attitude just gets in the way, doesn't help you at all, please, don't do it again.

These are all the codes I tested in different combinations:

I believe the problem could be that you tried several different combinations at random, and now you may not even know what the original configuration is, you need to keep the original configuration and change only what is necessary.

If you backed up the original configuration, use your backup before starting, otherwise I recommend you re-install it for warranty.
This video can help you (turn on the subtitles):

Changing dtoverlay=vc4-kms-v3d-pi4 by (dtoverlay=vc4-fkms-v3d-pi4)

Okay, other users have mentioned what you're saying, that in RPi4 you need to change in the config.txt file the line:
dtoverlay=vc4-kms-v3d-pi4
to
dtoverlay=vc4-fkms-v3d-pi4

Note: if you edit /boot/config.txt the changes will be restored to their original state after any upgrade, but if you edit the file /boot/recalbox-user-config.txt, the effect will be the same, but the changes will remain after updating.

But, see the link below, and do what is proposed (or, wait for the next version, as it is mentioned that it will be fixed):

• https://gitlab.com/recalbox/recalbox/-/issues/1836

And, as you can read here, some emulators might not work correctly after this change.

Unfortunately, it seems to be the only way to work for now, so make this modification for now, but be aware of these factors (that's why it seems more interesting at this point to modify this value in the config.txt file, since in the next update this modification will be eliminated,).

The Recalbox documentation mentions some recommended options to make the video work on CRT (our documentation is out of date, we are migrating the documentation and updating it, while we are in this update process, use the current documentation):
https://recalbox.gitbook.io/documentation/tutorials/video/crt/connecting-your-recalbox-to-a-crt-with-composite

The official raspberry documentation mentions all the video options available in the config.txt file:
https://www.raspberrypi.com/documentation/computers/config_txt.html#video-options

Let me try a step-by-step:

• Make sure you are using the correct cable (I know you've already stated this, but it's the first step)
• On recalbox-user-config.txt file, add:
  the supported sdtv_mode and sdtv_aspect as quoted here;
  hdmi_ignore_hotplug=1 and hdmi_force_hotplug=0
  and enable_tvout=1 as quoted here.
• Try also add the line audio_pwm_mode=2 , but as in some cases this causes slowdown, if the result is not good, replace with audio_pwm_mode=0
• Then edit the recalbox.conf file, and change global.videomode to default:
  global.videomode=default

This bug is still open, and a user mentions another workaround, check:

@zing bro I save backups of orginals 3 files to config.txt to user_config.txt and to recalbox.conf Then I tried all the combinations of the codes and restored when I had errors . But I can't get past another image of the 3 ghosts

@edwinsources Sorry, but you need to make it clear what EXACTLY you tested and what the results were, otherwise I can't help.

Did you try with the combination that I mentioned more than what is proposed here?

https://gitlab.com/recalbox/recalbox/-/issues/1836

And here?

@zing bro in that article that you share with me says something like that for the composite output to work it is necessary Modify dtoverlay=vc4-(f)kms-v3d But there is the failure that remains on the screen of the three ghosts of pacman And it is solved with Linux protocol And remove this overlay/.configs/pulse/default.p but I'm not a programmer, I don't know anything About Linux

@edwinsources It would be of great help if someone could share the 3 files already modified for me just to replace the files config.txt, user_confing.txt and recalbox.conf
