How to disable navigation sounds!

[dochyde]

Hello!

I'm getting tired of this "buzz" I get on my stereo.
I've tried searching the web and find no solution.

Ofc I have already disabled navigation sounds in Appearance but after an hour or so the sound comes back, even with the feature disabled.
It makes an awful buzzing sound on my stereo.

I use raspberry pi, analoge jack plugged into my R/L behind my stereo.

I am looking for a way to change config files manually to completely disable them or any other solution would be great.
I am using the "Official" release.

Thanks for your help.

Isn't there another settings under Audio?

I see nothing else.

Again I disabled it, watched a movie and it's back on, even though it says disabled in the settings.
Extremely annoying. :/

System/Audio/Play GUI sounds.

When I go to System then I do not have Audio.
I have Appearance/Video/TV Direct/etc...
No Audio.

System/System/Audio output/Play GUI sounds. It's where you select your audio output.

I don't have Play GUI sounds
I see Audio output, inthere I have choice between Analog/HDMI, I'm in Analog
Configuration of speakers
Amplify volume
Use speakers in stereo

Nothing else.

I am looking for a way to maybe modify advancedsettings.xml to turn sounf of navigation off.
I found sound.xml where the wav files are but the filesystem is not writeable...I thought to rename sound.xml to another name so XBMC would not find that file and not play the wav files in that folder.
