3. Delete Crystal INF in c:\windows\inf\other
4. Restart your PC for Plug and Play to reinitialize your system.
Known Limitations
1. Clicking the Stop button causes loud pops while playing Midi through Media
Player, when Headphone control is used.
2. Playing any wave using the Dsound application causes a loud pop when the
Play button is clicked.
3. After Remove/Refresh, no software wavetable audio is available after a reboot.
4. The Play and Stop button cause loud pops while playing wave through the
Media player.
5. There may be some feed back noise when Microphone boost is enabled.
6. A reboot may be required to play MIDI audio after the initial installation of the
driver.
7. Panning Headphone and Wave balance in the Output mixer while playing a
aWave/CD/Line-in signal causes a pop.
Special Design Considerations
1. The Headphone does not mute the audio when the headphone slider is adjusted
to the minimum value.
2. SW Synth slider jumps to max value, when Synth state is switched from Stop to
Play or viceversa.
3. Master Volume levels are quite low when compared to Headphone volume
levels.
4. Fastforward and Rewind Controls in the Media Player can not enabled.
5. When resuming from sw wavetable playback, midi is paused.
6. Digital CD Audio is recorded by loopback mux selection.
7. Mono Mix volume is low.
8. Some Dos games do not run in a Dos Box. This support is provided by the
Microsoft legacy Audio emulator.
