I've done some testing with my 2i4, and I think I have found a similar problem. However, it appears to be due to something in the kernel rather than the device. With my current kernel (3.11.0-14-lowlatency), U can't go below 128/2 @ 48k without getting nasty distortions of sound (which are basically like the sound shearing, but might be a bit clicky under certain circumstances). However, I fired up AVLinux, and I can go down to 32/2 @ 48k without this problem. I then tried a generic 3.0.36 kernel on my Ubuntu Studio setup, and although performance isn't that great (bit sensitive to moving windows etc. to cause xruns), I can get down to 32/2 @ 48k without any audible clicks or sound distortions.. Might be worth testing?
