skype meetings with more than 2 participants

[miwieg]

Dear all,

I recently bought ThinkPad T420s and I am struggling with Skype on that laptop.
The problem is that once I have a meeting with more than two persons, my speech signal is that much disrupted that I have to cancel the meeting.
The other participants report that they only get fragments of my speech signal.

The funny thing is that if I only have a meeting one person, skype perfectly works. By the way, the same persons who reported heavy disruptions, did not complain about the connection once I had a one-to-one meeting. So it cannot be the configuration of the other skype-participants.
I usually switched to my (very) old laptop (I even use the same headset). Even then, everything works (i.e. skype meeting with more than 2 people is not affected by any disturbance). So it cannot be my internet connection that is malfunctioning. It must have something to do with my ThinkPad.
The skype test-call also works fine.

Does anyone have a clue what is causing this?

Thank you very much in advance.

probably you don't have enough bandwidth to do so.

or to make sure contact skype support.

I really don't have any good answers, but what comes to mind is:

- have you tried with some other voice-over-internet service with multiple participants?
- does your soundcard have one or more input/microphone settings? Have you tried the other/s in such case?
- is soundcard driver updated?

Not much of answers I guess...
