Skype Speaker phone Voice cutting out help!

Im trying to Jam online with my friend.  You know speaker phone when your voice cuts out when the other person talks, that’s how skype works to.
Close as we got it to work was one side muted there mic, so one person could only hear themself while the other could hear both people.

My only solution to this would be to have 4 computers with 4 different internet connections

Or Can this be done with 2 computers on each side with one internet connection each

Might just be easier to go rent a garage like all the other bands looking to get a break.

buy rockband sounds easier

Skype has Full Duplex communications. Your problem is likely with bandwidth or a sound card setting, etc… Try lowering the microphone volume first
