The buffer size is the same, but in the 2 x 32 case, there are only two interrupts per buffer, so Jack has less time to fill the other half of the buffer. Additionally, the had-intel driver does not support linking of input and output streams. As Jack waits for both input and output to become ready before handling both streams, this will result in some additional delay for up to one period.
