It should buffer regardless of the stream format. It is possible that there's no data to buffer on the server. FLAC data is larger than MP3, and if you configure 30 second buffer on the server in bytes based on MP3, the same value will be only couple of seconds in FLAC.nelson c said:Hi Dmitry, I'm thinking of migrating the stream that is later broadcast on FM to flac. But I realized that the RadioBOSS buffer is omitted with this format. Is it a bug, or is it a technical limitation?
