Whenever I start VPN Client V4.7.00.0533, then I play any media (MP3 or WMA) with WINDOWS Media Player, the music plays for about 30 seconds, the left speaker goes out...then I hear nothing but static out of both speakers. If I disconnect the VPN, the medias play perfectly. I can reproduce this at will 100% of the time.
I can reproduce this problem on both of my laptops - IBM Thinkpad running WIN2000 Server and Media Player V9 and Dell Latitude running WIN2003 Server and Media Player V10.
Is anyone else having this problem?
I upgraded to V4.8.00.0440.
But the problem still exists.
Is it possible that there is a difference in the drivers/software for the network cards on WIN2000 Server and WIN2003 Server? I'm the only one where I work that is having this problem...and I'm the only one that has WIN2000 and WIN2003 installed on both of my laptops....and both of them have this problem?
Yes, and I have requested help from Cisco with no acknowledgement from them that there is a problem. Just waiting for others with Media Player to start complaining.
This problem exists in all versions of their VPN client that I have tried.
Trust me on this, try reverting to 4.0.4 if you can, just for a test. Also, what is the encryption algorythm in use for the VPN client? AES or 3Des...If AES, try having your admin change to 3des.. I haven't tried your specific issue but it's very close to the issue I'm experiencing with Windows Media Player and even Cisco's own IP communicator, audio cuts out after a few seconds while on the VPN. Switch to the 4.0.4 client or changing encryption (only can be done at the VPN) to 3des will resolve.
Yes, I have been complaining about it for some time, but it seems that Cisco doesn't know how to launch the VPN client and play a video with Windows Media player so it will never be fixed.
It seems that Cisco installs a version of Zone Alarm. I deleted Zone Alarm and WMP runs fine now. Hope this helps.
I have the same problem (with VPN 4.7 and 4.8). It's AES (128 in my case) that causes this problem with the cisco VPN client. I get the same audio static and then mute. Switching to 3DES solved the problem. Also the new 5.0 VPN client seems to solve the problem with AES.
