I am in place AA with a laptop. In another place BB there is a PC with Skype installed.
From place AA, I want to use the PC in place BB to make use of Skype to chat with people. Maybe with remote connection from place AA to place BB?
Yes, you can use Skype from the other PC through a remote controlling application. For this type of job, I recommend using Teamviewer as it has compatibility for multiple platforms and the sound is also mentioned in the features and it's available for different purposes.
