It appears the audio device can only be opened for in (record) or out (play). Is there a way to open it simultaneously for read/write (one waveIn and one waveOut handle)?

Hi Tom. I belive full-duplex audio control depends on the product and codec you're using. We've implemented a full-duplex CE audio driver using the UDA1341 codec on some of our products (but not yet the Bitsy, I understand). I don't believe the CE UCB1200 driver has full-duplex capability.

Can you let us know more about the product and codec you're using, as well as the application you have in mind?

We're using the Bisty, Windows CE 3.0.

We are assuming both the 1341 and the 1200 are on the board. However, only one device gets listed with waveInGetDevCaps.

The codec to use on the Bitsy is selected using a registry key (HKEY_LOCAL_MACHINE\Drivers\BuiltIn\WaveDev). Take a look at comments in the Bitsy ADSLoad.REG file for details.

Can you give us brief details about why full-duplex is important for your application? You can email privately if necessary. Thanks!
