Based on your post, I bought a Linksys WMB54G Wireless Music Bridge. It works, sort of, with my MC 11.
What happens is peculiar: MC's output can't be switched on-the-fly by the Music Bridge utility, even though this is how WMB is supposed to work, and other audio can be switched this way. It seems that MC locks onto whatever audio driver is active when MC is started.
The Music Bridge utility provides buttons to control where the audio goes -- to the WMB device (which is connected to my stereo amp across the room) or to the PC's local speakers. It does this by switching the active audio driver (confirmed by examining the PC's audio properties before and after using the utility to switch).
The problem is that MC's output doesn't get switched. I can dynamically switch other audio, such as the various sound effects used by Windows, to either the local PC's speakers or the remote WMB. But MC 11 goes ONLY to the audio driver that was active when MC was started. MC 11 doesn't follow Windows when the audio driver is changed on-the-fly.
I experimented with the MC's Audio > Output mode and settings, but they seem to have no effect. I assume that MC should be set to Device "wave mapper" to let Windows control which driver is used, but whether I use "wave mapper" or directly select either the PC or WMB audio driver, MC doesn't switch on-the-fly.
The only way I can find to use MC with WMB54G is to select the desired audio output destination BEFORE starting MC. This defeats one of the cool features, which is to be able to do some temp MC work locally (preview some tunes then build a Playing Now list) before switching to "broadcast" it to the stereo in the living room or wherever, without then restarting MC, reloading the Library, etc.
Ideas?
