Raspberry Pi crackling / stuttering sound

[j7yzjhk28z]

Hello,

I've installed Recalbox 7 Reloaded on my Raspberry Pi 2. The interface is very good, and the background music is playing normally without any problem while in the Recalbox interface (game chooser, etc.).

However, when I start a game (ex: a SNES game) the sound is distorded / crackling / stuttering.

The FPS is quite high ( > 30).

How to solve this?

Thanks

@j7yzjhk28z hey !
Are you using shaders?

Thanks @Scavy for your answer!

No I don't use any shader ; I don't know what it is.

I just did a default RecalBox 7 installation.

Steps to reproduce the error :

• Take a RaspberryPi 2 (or maybe 3 as well)
• Install RecalBox 7
• Launch any super nintendo ('snes') game (in fact it's the same with megadrive games)
• Use the default HDMI video/audio output
• You will hear distorded sound

Any idea @Scavy ?

@j7yzjhk28z Can you test with another HDMI cable?
There are several versions of HDMI cables (1.1, 1.2, 1.3, 1.4, 2, 2.1), do you know which one you are using?
Can you test it on another TV?

Maybe this will help you:
