Iam using BT4 R1 in a persistent USB drive and using it in three machines.

Desktop
DELL Inspiron 1525
DELL Latitude 630
There is no problem in the first two machines.

But in the Latitude, there is a UDP multicast traffic followed by RTP traffic (sound 16 bit ) to the same multicast address. (For eg)

192.168.0.1.45232 > 224.0.0.56.46812

The result is that BT4 is not quiet and it is quite difficult to work with wireshark.

I found a reference to such a problem in the below mentioned URL.

https://bugs.launchpad.net/ubuntu/+s...io/+bug/411688

But I do not find pulseaudio in the BT4 distribution.

Apart from BT, I have installed Nessus but this does not start by default. All observations are without Nessus running.

Any help/suggestions in this matter is highly appreciated.
