Hello. I'm testing out Windows 7 RC on a Latitude D830 laptop. The problem I'm having is that the audio drivers
that come with Windows 7 work fine, but they don't recognize when the laptop is docked into a port replicator. So when the laptop is docked the external speakers plugged into the port replicator don't work; all sounds come through the laptop's internal speakers.
I had a similar problem with Vista, so the way I fixed it was to download & install Dell's drivers, which corrected the problem.
However in Win 7 RC, I've tried Vista's drivers, and they work up until I encrypt the laptop using Winmagic's SecureDoc 4.6 client, then the drivers fail to load on restart and no sound will work. The only way to get them to work again is to roll back the drivers to Win 7's default driver
I've tried this on a Latitude D820 with the same drivers running the same SecureDoc and they work fine.
Has anyone run across a problem like this? Unfortunately removing SecureDoc is not an option at this time.
