I checked again the HDMI connections and after unplugging, plugging again it worked.
So thank you for your help

@scavy
The problem appeared after upgrading to 8.0.0, 8.0.1 and 8.0.2
Before I had sound through HDMI and the hdmi was alteady not shown.
But ok, I will check what you propose and keep this thread updated

@scavy
Thanks for your answer
No it is not shown, I explained it in my original post

-> in recalbox UI, I am not able to switch from "jack" to "HDMI" (HDMI is not shown)

@alvin I tried both hdmi outputs
Thanks for the hint, but it did not change anything while changing the hdmi output

Dear community,

The issue is simple : no audio signal through HDMI.

I have searched a long time before posting, I can't find how to fix this issue.
I have been using recalbox since a long time, on RPI3 and RPI4.
I never had such issue before recalbox 8.

I have tested the following :

• forcing HDMI in http://recalbox web page
• installing a new 8.0.2 on the SD Card (instead of upgrading)
• in the file /boot/config.txt, I have put in comment this line #hdmi_force_hotplug=1
• in recalbox UI, I am not able to switch from "jack" to "HDMI" (HDMI is not shown)

If anyone could help ??

@luc1anocruz I solved it by remove the se card and install 8.0.1 from my computer

Hello everyone

I just updated from 8.0 to 8.0.1 on a PI4
Unfortunately, I get a rainbow screen at startup.
I checked existing issues it could be a power issue or raspian version mismatch

My hardware was working fine before updating so I don’t believe it is related to the power supply

Any idea ?

Bonjour,

J'utilisais ma manette 8bitDo SF30 Pro sur mon PI3B+ sans problème, et depuis que je suis passé sur Pi4B, la manette semble avoir des problèmes de latence dès que je dépasse 1m30 de portée.

Mon matériel :

• PI 4B

• recalbox 7.1.1

• Boitier NESPI

• Manette 8bitDO SF30 Pro

J'ai testé les différents conseils du forum (désactivation du WIFI, appairage en mode android, c'est pareil en mode switch).

Est ce un bug connu ?
merci pour votre aide

Bon dimanche à tous
