Hi all,

I have several Focusrite Scarlett USB interfaces:
- Solo
- 2i2
- 2i4

They work out of the box but I noticed some flaw in either their
firmware or ALSA or jackd:

- with 48000 I can use much lower buffer sizes (down to 32) as with
  44100 (at least 96)

- with 44100 I have some slight clicks, about one per minute, sometimes
  less. Those clicks sound as if an electrical device (refrigerator,
  lights) was switched on.

- with 48000 I have no such clicks.

Has anyone made the same experiences? With Scarletts? With other
USB-Interfaces? Is jackd or ALSA optimized for multiples of 48000
instead of 44100?

Regards
Holger
