i found the error!
i always connect the server via remote desktop, and with the remote desktop i have this error. strange, because in the client i can decide between no sound, sound on server, sound on client and nothing works correct.
i uninstalled the driver and boot new and installed it new but nothing work.
so i tryed the usb headset who works without installing a driver, but no sound ;-(
it seems a little bit strange in the Device Manager all seams ok
I have a intel athom 330 board with windows 2008x64 sp1 and everything work great exept the audio!?
It is a Realtek* ALC662 audio codec (5.1 channel HD audio) Chip and i installed the new driver R2.21, in the readme stand that it works with Windows 2008 and yes when i plug in a speaker it pops up and ask me if it is a speaker.
In the Device Manager everything look ok.
I also activat the WindowsSound service.
But Windows say that there ist no soundkard?
