Synchronize Sound Cards

mwigtkm · Apr 17, 2007, 11:57 PM

I have 3 Sound Blaster live! Value cards in my MP3 server. I have it working flawlessly with xlobby and can output independently to any of the 6 zones. The problem I have is that I can sync zones as long as they reside on the same sound card. If I try to sync zones to different cards, I begin to get an echo and the songs slow begin to space out. I believe I read that is due to each sound card using a slightly difference clock speed. Is there anyway with the Kx drivers (that I already use) to synchronize sound cards?

Try asio4all on top of kx wdm. At least, it works for me.

The common method of syncing cards with kX is to tie them together with S/PDIF cables.

One card is the HOST and the other ones the clients.

You could use 2 SPDIF outputs from your HOST card, sending 1 each to SPDIF inputs in the other cards. This takes a bit of DSP manipulating but it wil work if I understand correctly what you are planning to do.

I won't elablorate anymore at this point in case you have left the planet.

Yell if you want more info and I or another kX user will jump in.
