Pi audio quality

[scamper]

Has anyone experienced poor audio quality from their Pi this year?
Last year with the same setup and same mp3 tracks, i had good audio quality being transmitted.
I could pick it up on all my radios and it sounded great.
This year though, I have tried adjusting the gain of the transmitter and lowering the volume out of the FPP, but I am finding it is distorted.
The only change to my whole setup is that I updated to the latest version 1.8 of FPP
Could there be a difference in there? Or should I be looking deeper into the problem, maybe rfi or something?

I had issues with sound quality on my pi last year running 1.6 and it was intermittent.
This year I bought one of the cheap USB sound cards and plugged into pi.
WOW, what an improvement! Cost was 3$ from china and to tell the truth I never thought it would make a difference but it is very noticeable, audio is as clear as can be.

+1 on the USB sound card.

Hmm might get one also. Sound not as good this year- getting distorted. Acceptable with Pi volume down and amp vol up but sounds like ( pardon pun) sound card is the way to go.

I just bought one of these: https://www.aliexpress.com/item/Color-sent-randomly-USB-Sound-Card-USB-Audio-7-1-External-USB-Sound-Card-Audio-Adapter/32602874245.html?spm=2114.13010608.0.0.A0Ess5
When you get one, don't forget to change audio output adapter to USB audio device in FPP settings.

I purchased a 3 channel mixer while I was waiting for my usb sound card to turn up. This by itself has made a massive difference plus gives you a bit more control. I am still yet to receive my usb to 3.5mm to see if that has any effect at all now.
