@ian57 Merci beaucoup !

Hello,

Since version 7.0, I have a problem with the sound from a raspberry pi 3 jack.

On each reboot, the audio settings of 'recalbox.conf' changes.
the line:

audio.device=jack

by

audio.device=Default output

At this point the audio dont works and I am forced to replace by hand "Default output" by "jack".

According to the log something is wrong with 'amixer' and access :
