My music library is on a USB flash drive plugged into my TP-Link router. Speaker system comprises two pairs of Ones and one pair of Era 300s.

 

I cannot play anything from the music library on just the Eras. Music library plays fine on both of the One pairs. I can get the Eras to play from the library only if I’m already listening on the Ones and then group in the Eras.

 

All external streaming services and Airplay from my phone work absolutely fine on the Eras & they sound perfect.

 

When I try to play direct from the music library to the Eras, the Sonos app says “Content is unavailable”.

 

I’ve done a factory reset on the Eras and this hasn’t helped. I’m hoping you can though!

I see more complaints about the music library not working on the Era's while other speakers in the sam system have no problems. You could make a diagnose and call Sonos - if only to make them aware of the problem.


Does anyone have a local music library working on an Era 300? Local drive on a PC, NAS - anything, please let me know.


I have same/highly similar problem- can only play from the music library, which resides on a thumb drive in the router,  to a Sonos One speaker.  Fails to both era 100 speakers with the error “content is unavailable.”  Unless the era 100s are joined to the Sonos One then they can play from the music library.  Era 100s work fine for streaming services.  
 

I will submit a case with Sonos.

Agreed - sounds like just the same problem.

 

I had a two hour call with the company trying to troubleshoot this. Extremely helpful agent who tried so many things to help try and isolate the problem but alas no success. Would like to know how you get on.

 My 300s are now surround speakers, but when I had only one it played local library music OK.  Once I purchased a second 300 I made them surrounds.  Never tried them as a stereo pair so not sure what impact that would have had.

 First make sure all your speakers etc are on the same firmware version. 
 
 I am not using a drive attached to a router.  Mine is on a NAS.  If you have the option try to create a test music folder share on a PC.  Put an album in that folder.  Index it then see if it plays on the speakers in question.

Good suggestion, thanks- I’ll give that a try.


I did open a support chat - reproduced the issue - they said “not expected behavior” and asked me to call.  I called and had a three hour phone call, reproduced the issue many times, and they didn’t resolve the issue.  They thought it might be an old version of samba SMB on my router and I checked my router has firmware supporting SMB v2.  I feel like they have a bug.

They had me create a shared folder from a PC and that did work.  Guess I’ll use that.  The case was left open and I was told I would hear from an escalation person.  Been 6 days and I’ve not heard anything.  T
