MP3 tracks at 320 kb/s and 48 kHz do not play on Google Chromecast

How do I do this? As I said, I can find no documentation as to how or where to do this.

And as said a couple of times I’m not Navidrome support …

A quick Google gives https://www.reddit.com/r/navidrome/comments/1l1v8pl/help_with_transcoding_on_web_ui/ that explains all …

I simply don’t understand. I thought you built the app and were the one to do support?

I built Symfonium …

Symfonium can connect to virtually anything, I do not do support for every possible servers in the universe …

Your need is to configure Navidrome server to force the lower sample rate, this is something on Navidrome and I do not write nor do the support for Navidrome.

Fair enough. I got those backwards in my head.
