Soundbridge / M1001 / Factory Reset / No Sound

Hello,

i have a Problem with my Soundbridge M1001 since it was nessessary to set the Factory Reset.


Years ago I did a Firmware update to version 3.0.52 and it worked since then with all my Logitech Media Servers in different versions.
Since the Factory Reset i have Firmware 3.0.44. I can connect to my LMS but i have no sound at the analog Output.
I can rule out that the Soundbridge is broken because i have Sound on the same analog Output when i try it with Windows Media Player.
The current Version of my LMS is 7.9.2 - 0023.1559540205.
Maybe anyone has an idea what i can do to continue to use the M1001.

thanks,
sky
