I move the xrand line from the end of the file to the next line after the externalscreen script call and now it works

#/usr/bin/externalscreen.sh &
/usr/bin/externalscreen.sh
xrandr -r 60

Thank you for your help

I have updated the xinitrc file but it does not fix the issue.

I also changed the /usr/bin/externalscreen.sh call by removing the '&' to be sure that the script has ended when the new xrandr command starts.

Hello,

I already had the same issue with Recalbox 7.0, but it was fixed with the 7.1 version (I didn't really search for a fix at this time). The issue comes back with the 7.1.1 version.

When I play with emulators (Snes, Genesis, PC engine...): I have sound glitches and the command don't respond correctly... I discovered that the vertical refresh rate is set to 60Hz, but the reported display refresh rate is set to 50hz.

With the previous version I have this and all is working perfectly:

I try to find a fix and discovered that it's related to the screen detection, but I did not find the way to set the it correctly.

The xandr report give me this:

And if I run the following command, the settings are ok:

xrandr -r 60

I tried to add this setting in the recalbox.conf with no success:

global.videomode = CEA 16 HDMI

If anybody can help me to fix this

My system:

• Recalbox 7.1.1 X64
• PC/NUC Model : CORE I3-4010U HD 4400 4Go (NUC D34010WYK)
• USB Key SanDisk UltraFit

Thanks for your help.

@Le-Commandant said in "Tremolos" sound with Mame - Recalbox 7:

tremolos" and bad quality of soun

I have the same issue with a NUC i3 - D34010WYK.
I didn't try with the analog output.
