Can anyone provide detailed, step-by-step instructions for getting the Audigy 2 ZS to synchronize audio playback (WAVE out) with another sound card (Yamaha SW1000XG) as the timing master? Is this even possible? I've seen this mentioned in other threads (i.e. chaining several Creative cards together so they are synchronized, connected via S/PDIF) but the detailed instructions seem to be on web pages that no longer available. I have tried connecting the SW1000XG S/PDIF out to the Audigy 2 ZS CD-S/PDIF input. This connection works (Audigy registers CD-S/PDIF input and routes it to output without distortion, pops, etc.). However, when I try to play a WAVE out, that audio is garbled (but the audio from CD-S/PDIF in continues to play well). I perform this test within Sonar, with the SW1000XG WAVE #1 set as Timing Master for both playback and record. Sample rate set to 44.1K. By the way, when I set the Timing Master to Audigy, then it plays fine, so I know there is no electrical or installation problems with the card or driver. Within KX project, I have set the S/PDIF rate to 44.1K. I've tried "Direct S/PDIF Record" option but that seems to make no difference. By the way, the DSP Factory cards can only operate at 44.1K sample rate. My System: Windows XP Dell Dimension XPS Gen 4 Audigy 2 ZS KX project driver rev 3537, WDM Yamaha DSP Factory (SW1000XG w/ PLG150VL and DS2416), WDM Dspctrl3 software Sonar 4.03 I would like this function to work so I can directly record the outputs of the Audigy Synthesizer + Effects to a Wave file. I plan to do all my external recording through the DSP factory, so I'm only concerned about recording Audigy synth to Audio within the card. I suppose a workaround would be to switch "Timing Master" back and forth between SW1000XG and Audigy, as needed.
