Hi!
I am using the audio settings for audio normalization on my Raspi 4:
While running a video, entering the audio settings and set "volume" to -30 and "volume amplification" to 20. After that I used the button to set that as standard for all movies.
I dont know if this is the best way to to normalize the movies - but it worked so far for me.
But since LE11, only the setting for the amplification is persisted and available after a reboot. Volume is set back to 0,
(when savong those settings as standard, I can see "info <general>: Deleting all video settings" in the log and guisettings.xml is updated. but i cannot see that volume value anywhere)
I guess this is a bug and just wanted to report it
