NAS & WMA - No Longer Working

All of a sudden my Sonos will no longer play WMA files from my WD NAS Drive.

I can navigate to the folder/track etc.

Song starts, i get approx 1 second audio and then nothing, track still shows as still playing.

Leave it running i get sporadic audio for about a second every now and then.

There is no changes to NAS, Router in terms of setup / config. Rebooted both, still the same.

Have updated teh music library several times.

Its the same fro all speakers, play 1, One, Roam, 300 etc.

System quite happy to play FLAC Files, no change there.

Any ideas, greatly appreciated.

Hi ​@richardbsimpson 

Welcome to the Sonos Community!

I’m sorry to hear of this issue you are having with playing WMA files on your Sonos system.

This is a known issue which we are investigating, though we have no estimate for when a fix might be available. Please cease troubleshooting, as you will not be able to address this yourself.

The only known workaround is to convert the WMA files to another format.

I hope this helps.
