Noisy Audio

[Anonymous]

I can’t use HDMI audio for the project I have on at the moment, but the sound I’m getting from other methods is terrible.
I’ve tried both the 3.5mm jack and a USB adapter and both are very noisy / crackly. I’ve done a search on here and tried all the methods I could find; dither settings etc. but none have worked. I’m sending the audio from the pi into a small amp (the amp works perfectly crackle-free when connected to my phone).
I’m wondering if anyone else here has had bad sound output, and how they fixed it.
Thanks!

You’ve looked at this page as well?

I’ve always had issues with the composite cable, and only ever gotten sound to work favourably with HDMI.

Yes that’s the one I tried, but unfortunately nothing helped.
Strange that the same noise is present when using a USB adapter too though, isn’t it?
The only workaround that I can think of at the moment is to use an LCD driver board that handles audio as well as video, but that’s an expense I really wanted to avoid. Ideally I wanted to run sound pi>amp>speaker.
Any ideas?
Thanks!
