Cisco VPN Client causes sound problems

I have strange problem with Cisco VPN Client and Windows SP2. When connection to VPN concentrator is enabled I hear noises in speakers. I hear proper sound but it's mixed with random beeps and statics. Problem occurs when any multimedia application is used. Windows Media Player, Winamp, TV Tuner, Skype - always the same noises. I'm unable to watch movies or listen to Internet radio or mp3 when VPN connection is established. When I disconnect vpn tunnel problem disapears. It seems that it's also hardware independed because I've checked 5 completely different computers with same results. I've checked version

4.8, 4.6 and 4.9 beta - no difference. CPU load is at 5 to 10% in task manager. It looks like some Cisco driver do really bad things to Windows kernel.

Any clue what might be wrong or walkaround?

Hi Berry,

I can confirm that I have exactly the same problems with my machine, a dual core 3GHz Dell PC with 2Gb of Ram.

Took me to buy a separate USB sound card to realise that it was the VPN software causing the problem (work from home, VPN up 99% of the time)
