[Sonos] FLAC transcoding

There is an EstimateContentLength param you could try.

Sonos + Emby: it's not a transcoding problem, it's a delivery problem

I hit this building DLNA casting into my own client, and the fix turned out to be somewhere nobody seems to be looking.

This is contradictory to your previous reports because you had been saying that it was never attempting to transocde at all.

I tried it — it does set a Content-Length and drops the chunked encoding, but the value is an estimate: 7,849,714 promised against 3,920,748 actually delivered on a 23-second track, the same figure for FLAC and for WAV, and the connection closes at the real end. For a renderer that needs an accurate length, that fails the same way a missing one does.
