For Windows 7, 64 bit: I have a digital SPDIF output to my stereo, which controls speakers in other rooms. I also have a set of speakers connected to the regular audio jack at the computer. This allows me to send music to the kitchen while my child plays games on the computer. Works great. Except when I'm playing games and still want to listen to music. ;-D
I know I can manually switch WMP to play through the speakers instead of SPDIF, but I was wondering if there's any way to enable simultaneous audio out in Windows 7? Virtual Audio Card is a non-starter because I'm running 64 bits and the VAC driver isn't signed.

There is no way built into Windows 7 to play the same audio on multiple output devices. You can play different audio to different devices, but would need some add-on software to play to two different devices from the same application. Applications could make it possible as well. For example, VLC could choose to output to multiple audio devices simultaneously, but rarely do programs do so.
