Similar problems....I was told it could be a problem with the firewall you are using...it is blocking audio. This seems to be a very common problem, and is receiving too little attention by the software makers....why? I don't know. I would like other users to add comments here. What is your operating system and are you using an additional firewall?
I am having problems with receiving audio from my contacts. they can see and hear me fine but i can only see them. All my settings and devices are working. When i tried to test sound hardware it couldn't complete. I got the error 0x80150175 and the message that windows could not execute DPVSetup.exe and to use add/remove to install. I went to microsoft who are aware of the error, followed their advice but it did't work. I use XP,Toshiba satelite m30-107 note book and a logitech Quickcam Pro. there is no problem with my contacts setups as they can all comunicate with each other no probs.I'd be grateful for some advice thanks
