Hello again Asyn,

My earlier problem was fixed thanks to your advice.

But I am still having a different problem with Avast Firewall & Sonos & Win 10 (64 bit).
When Avast firewall is activated and Sonos Controller is open and PC goes into sleep mode it crashes now and then. I am not sure if it is in sleep mode, or just when entering into or just leaving sleep mode.
Have now tried a few different things, but whenever Avast Firewall is deactivated it will never happen.

Hope you are able to give me good advice also on this matter.

Best regards
Gunnar
