Server emits stream_url as a relative path (/api/tracks/{id}/stream, internal/api/convert.go:75). PlayerController.toMediaItem passed it raw to setUri, so OkHttpDataSource saw a host-less URI and silently failed -- queue UI loaded but no audio played. Route streamUrl through the same resolver used for covers (resolveServerImageUrl), which prepends the placeholder.invalid host that BaseUrlInterceptor rewrites to the live server with the auth cookie. The setCustomCacheKey(id) still keys the SimpleCache by trackId, so cache residency is unaffected by the URL form.
