Sample rates higher than 48kHz produce no sound in my setup both in pure alsa mode and pulseaudio (with default-sample-rate: 192000 or 96000 in /etc/pulse/daemon.conf) modes. Following strings shows that audio hardware is set to this mode with no alsa resampling or something similar.

P.S. Sorry for using non stock kernel this is due to https://bugs.launchpad.net/ubuntu/+source/v86d/+bug/1080530 (build from #22 with single patch applied) but problem can be reprodused in "pure" setup.
