F1 2010 Bluetooth issue

[Woodson155]

A buddy and I have been racing online against each other (filling the field with AI) and have been able to chat no problem. Finally got another buddy set up to join us but we have a Bluetooth issue. I can hear both of them and they can both hear me, but they can't hear each other. They each have an X beside or over each other's name. They have tried "unmuting" but it doesn't work. Are we missing something obvious?

Thanks.
