Mark, he's right; for ASIO the buffers adjustment is in the ASIO controls, not BIAB. Some less expensive cards just allow a choice of three settings, loosely called recording, playback, or something averaging those. If that's what you have, you want to use the Recording setting for the fewest buffers. Then you may have to change to the average or playback setting for playback, especially mixing.

Is that one of the old M-Audio 2496 cards? I loved that card in its day. It should still be capable of low latency but only assuming the drivers have kept up. You didn't say what version of Windows you have. If it is 10, is there even a driver for this anymore? Tell us more about your system.

By the way, you are correct about latency. I've read that a good player is not bothered until it gets longer than maybe 6 or 7 milliseconds.
