Question related Fix for “unable to connect” @ Julien: You recommended -deinstall your virtualbox
Do you mean “Oracle VM VirtualBox”? This software is indeed running on my Laptop with Win 8.1 and I always get the above mentionend error message from Sonos software (for Play 1). I tried most recommendations on SWHY configuration given in this forum, but nothing helped. I took me a long time to configure VirtualBox, so I want to be sure that this has solved the problem on other computer. And what happend when you reinstalled VirtualBox later? Does the error return?
