Crackling when increasing default-sample-rate

[Nazar Mokrynskyi]

I'm on Ubuntu 15.04 x64.
Just bought Creative Sound Blaster Omni Surround 5.1 USB sound card which is capable of 24bit 96kHz.
I'm editing sudo gedit /etc/pulse/daemon.conf changing:
default-sample-format = s24le
default-sample-rate = 96000

When I put first line everything is fine, while I'm putting second, even 192000 - I'm getting random crackling all the time when something is playing.

Without second line everything works fine.
I've tried many tricks found in Internet, different kernels (stock 3.18, manually compiled 3.19.0 and 4.0-rc1) - the same result everywhere.
