I have a soundtouch 20 and two 10s. All speakers work fine when used alone but they won't work together well. I can add the 10s to the 20 in the app, but while the 20 will play the sound, the 10s do so only very unreliably, even though they are grouped together in the app. Perhaps the 10s will sync after some seconds, but after a random time (in the seconds) one or the other, or both, will go silent. Fast-forwarding to the next song sometimes get's them in sync, but most of the time not and sync will drop again quickly.
I have tried making a 10 the master and syncing the 20. Music then plays ok on the 10, but then the 20 has sync issues.
The devices are connected ok to the WLAN (I can see the left led is bright) and seem to also connect to the soundtouch master, as the right led starts flashing initially and then settling to bright. However, even though the right led is bright, the sound may drop while the led keeps being lid in bright. Or the right led goes bright but no sound played from the speaker at all.
All three devices where bought in short succession from the same vendor, and I updated the firmware on all of them when prompted uppon first connecting them to the network. I am using a NAS to store the music, but the problem also occurrs when playing an internet radio station. I have also moved the speakers around the room to no effect. The router is in the same room, but some meters appart, to router connectivity should not be the problem.
This is very frustrating, because I bought the system hoping to just turn it on and play music, rather than having to fiddle with it.
Can someone give an indication about why no sound would be played from the paired speakers even though the soundtouch (right) led is bright? I suspect that perhaps my router may be to blame, as it comes with a very cheap plan, but as it sometimes works the problem seems not to be a missing feature in the router.
Thank you very much
