Using Kodi on an old Raspberry. Formerly with HiFiBerry but I think the DAC in my amp is half-dead (weird white noise after a couple of minutes, regardless of the source) so now I use Pi→HDMI→TV→RCA→Amp…

it’s becoming hard to distinguish this thread from Sound solution for a home 2025?.
By the way, if you’re using Linux (or WSL2?) and buy MP3s or FLACs and, like me, are tired of messed up metadata and titles in all caps and stuff, you might be interested in my “bandcampetc” project.
