Loud distorted/crackling noise

I’m loving OSMC so far, it’s great but whenever I try to play anything out of the 3.5mm audio jack, I just get a loud distorted noise over the actual audio. When nothing is playing it is very loud, when something is playing it is a little quieter. If I lower the volume on the system and increase the volume on the speakers it gets worse. I am running the latest build of OSMC and the raspberry pi is brand new.

It is not an issue with cables/power/speakers or the settings as I have tried many different ones of each and it does not happen with other distros, such as raspbian. The audio through HDMI is fine, but at my desk I connect it to a monitor that does not have speakers so I need the 3.5mm jack.

I found a similar post from before but there was no solution:

The person just bought a USB sound card and used that to play audio to speakers.

Does anyone know why this happens or how I can fix it?

You can try the new audio improvements.

Wow. This worked perfectly, absolutely no distortion whatsoever with speakers or earphones. Thanks!

Amazing fix Sam thanks :slight_smile:

Thanks for the tip, sam.

Just noticed sound is very muffled using this fix especially during music.

I guess this is to compensate for less hiss and distortion.

Is there reason why raspberry pi 3.5mm jack has lots of distortion and interference?

A great improvement anyways. Keep up great work sam.

Rpi 3.5mm has never been known to be anywhere near audiophile quality. Quite the contrary actually.

Because it’s a PWM filter.
