In Reply to: One thing to add is that there are multiple stages of buffering on computer side. posted by carcass93 on September 19, 2014 at 11:41:12:
With the USBPAL driver and ASIO interface to HQPlayer I have three parameters, the USB buffers, the ASIO buffers and the HQPlayer buffering. Also, there are two buffer error counters in the driver, one for USB and the other for ASIO. In addition, there is a third counter that can count up and this is buffering related, but it also is said to relate to data errors on the USB. I suspect this relates to the signaling back from the DAC to the driver, but exactly how is not clear.
One thing I have noticed is that if I set the USB buffers to the minimum and overload the computer there will be lots of errors showing up in the counters, but most of these are inaudible. On the other hand, increasing the USB buffers to the maximum results in few errors (even if the computer is grossly overloaded) but when they hit they are highly audible. Best sound comes with a small set of USB buffers and taking care not to overload the computer. The sonic effect of other parameters is less obvious.
