Help ! Synology / Minimserver / Ministreamer / Bubble / Lumin app / Chromecast Audio

[Cebolla]

Hi Snico

The thread that link is referring to is quite old and BubbleUPnP Server, the Linn Kazoo controller app mentioned in the thread and even MinimStreamer itself have been updated several times since, so any problems highlighted then have more than likely been sorted out since. I'm certainly having no issues at all using BubbleUPnP Server providing OpenHome renderer for the Chromecast Audio and getting MinimStreamer to do ALAC & DSF DSD file transcoding to WAV.

In theory, you don't actually need MinimStreamer to do any transcoding when using BubbleUPnP Server with the Chromecast Audio, as the BubbleUPnP Server should automatically transcode to WAV any audio file format the Chromecast Audio doesn't support. However, you don't have any control as to what sample rate and bit depth is used by BubbleUPnP Server's transcoder, since it is all done for you in the background and there are no user settings. For example, all DSD files are always transcoded to 16-bit 96kHz WAV by BubbleUPnP Server for the Chromecast Audio. Also, there is an issue with the BubbleUPnP Server transcoding some ALAC files for the Chromecast Audio, in that they don't play.

So, if you need to transcode ALAC files and/or you prefer to be able to chose the resolution yourself, you should use MinimStreamer to do the transcoding instead. There should be no interference between the two, since MinimStreamer's transcoder will enagage first, so BubbleUPnP Server should always 'see' MinimSreamer's transcoded file, not the original file.

Are you certain you are playing MinimStreamer's transcoded files in the Lumin app? For example, if you are using a playlist created before you made the transcodings settings change in MinimServer, the music tracks will still be referring to the original ALAC & DSD files, not the transcoded WAV ones. You need to recreate your playlists in the Lumin app, so that the music tracks refer to the transcoded WAV files.
