Hi, I wrote a couple of weks ago about a device routing issue...

The app would try to record on, for example, device 0, but the recording would actually happen from device 1.

The problem was at the application level....The application was using waveOutDevGetCaps() to get information about the available devices.

But, then it was using the device numbers to call waveInOpen().

It seems that sometimes that will work, but not always. Sometimes device-0-In is mapped to one sound card, and device-0-Out is mapped to another sound card.

One must use waveInDevGetCaps to get information about the In Devices and waveOutGetDevCaps to get information about the Out Devices.

Just FYI in case someone else has a similar problem.
