SONOS not playing specific files

Dear all
I have a very special problem.
I have organized all my music on a Synology and play them via SONOS. Always plays perfectly.
I copied now an album which I received as WAV files after converting into FLAC on the Server.
The album is shown as all the others and can be played from the PLEX web and mobile devices.
But on SONOS I got the message: Playing not possible. Connection to PLEX broken.
All other files work. Only the ones from that album.
What could be the reason?
Thanks.

I converted thousands od CDs with EAC and had never problems playing them.
I got now from the artist directly WAV files from album which is out of stock.
So I have no CS but all the WAV files.
I converted them with the same EAC installation but obviously with another menu option: compress WAV’s (Alt-V).

And yes the info is different:


No idea what I can do differently.

What version of Plex Media Server are you running?

I noticed similar behaviour after adding a new album after updating to version 1.23.5.4841 which included:

  • (Analysis) Music file bitrates contained bitrate for more than just the audio track.

I reverted to version 1.23.4.4805 an re-ran Analyse on the new album which resolved the issue for me.

I tried version 1.23.6.4881 with the same results and again reverted to 1.23.4.4805.

I’ll re-try 1.23.6.4881 next time I have an album to add, probably after Bandcamp Friday, and will post logs if I experience the same behaviour again.


My version.
Via webbrowser the file is played.

Will do when it’s not going be disruptive. It’s evening here and a few of the family are mid-movie/mid-episode.

What can I do?
The files are playing perfectly on the web and on my android phone.
Just not via SONOS.

Ok.
But is this a general problem when adding new music or jsut with that specific file I have?

Whith this version it


works perfectly.
Many thanks.

I have the same issue, although all my files are flac, some play through Sonos and some don’t, everywhere else they’re fine.

The ones that don’t play display the ‘connection to Plex lost’ error.

My server is remote and was working fine. perhaps it’s also an update issue, unfortunately I don’t think I can roll back the versions on my server as it’s kinda handled by the company, I think.

Any help would be appreciated, the frustration levels are high

Similar is happening to me as above, I’ve noticed this warning in the console.

I’m not sure if it’s related but we get the same error

Potentially useful additional information:

Still on server version 1.23.6.4881

  1. Add album Exiscens by Kerreta (which is FLAC 48/24 where the other 2 albums are 44/16) to “Music - Test 1.23.6” library

That’s the step-daughter watching Deadpool 2.

For each successful track play I can confirm I was able to hear the music playing via 1 x Sonos Port and 1 x Sonos Connect and I let each track play for at least 30 seconds.

Sorry, I didn’t notice the server-synology tag, just the sonos tag and that the behaviour described by the OP matched what I had experienced. Do you propose I create a new thread?

Thank you. Will do.

I noticed whatbox in the logs, is that your server?

Yes, I use Whatbox for a PMS shared with family. Best if you message me directly if you have questions which don’t relate directly to the Plex for Sonos FLAC analysis issue.

Having the same exact issue with flac44/16 music. It seems like Plex is analyzing the files incorrectly. On a flac44/16 file that does work it has more metadata in the media info page (album gain, album peak, album range, gain, loudness, lra). None of that exists on files that fail to play through Sonos. Also like others when it fails to play there is a warning on the console

WARN - [Transcode] Streaming Resource: Bandwidth exceeded: 2147483647 kbps > 160000 kbps

I’ve tried re-analyzing files a dozen or so times but nothing seems to work. Playing from the web and casting the audio to the Sonos speaker does work but the experience is a big sluggish so I prefer using the Sonos app for music control. One thing that is interesting though is that when using Plex Web player to play through the Sonos the activity never appears on my Dashboard.

If that doesn’t work, share a sample file?

Plex recently addressed one issue with video files not analyzing correctly, resulting in requiredBandwidth == 2147483647.

requiredBandwidths == 2147483647 for files with attachments

Perhaps these FLAC files are malformed, or perhaps there is something about them (an attachment, etc.) that confounds the analyzer.
