What Is the Game Compatible Audio Device?

MORE INFORMATION

Certain modems install a Wave Device For Modem device that appears in Device Manager. With this driver, wave input/output (I/O) data is sent through the PC's communications (COM) port to the modem. This serial wave driver supports IMA ADPCM and Rockwell ADPCM formats, as well as 8 kHz, mono, and 16-bit PCM format wave data. Some drivers may also support 11.025 kHz, 22.05 kHz and 44.1 kHz, mono, and 8- and 16-bit PCM format wave data. This is separate from, but similar to, the usual Sound wave I/O device used by most Windows-based games.

The Game Compatible audio playback device is a component of this driver. The Wave Device For Modem device may also include other components, such as:

• Voice Modem Wave #00 Handset
• Voice Modem Wave #00 Line

The exact components names may vary from modem to modem.
