Team viewer's audio and share other person's screen capability

I started to like the team viewer tool as a pair programming tool. Here are two things  I would like to ask:

1)Is there a way to enable the audio so that we talk to each other during the Team Viewer session instead seeking help from **bleep** audio?

2) My teammates connected to my machine and use my screen to code. We encountered something not working in my machine but the same thing works in his machine. So I said, can you share your screen, He said there is no way in the current Team view session, and he had to start a **bleep**, from which he can share his screen and I also can switch to share my screen. You can see we have to manage both **bleep** and Team Viewer. Is there a way for me to see his screen during the team view session (on my machine).
