You have been subscribed to a public bug: 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.
