The noise issue when changing channels

[BeLikeElon]

When switching channels, there is sometimes an electrical noise, which becomes more noticeable when the bass is turned up on the equalizer. I'm unsure if this is an isolated case, as I've encountered this issue with several Yoradio units I've made. If it's not an isolated issue, I hope this problem can be addressed and fixed. Another issue is that during channel changes, the audio sometimes seems to suddenly cut off rather than transitioning smoothly. However, at other times, the channel change does occur smoothly
