default-sample-rate sets the default sample-rate used by PulseAudio. Modern digital audio equipment can usually handle 48000 just fine. Using 96000 would also be fine if you only use a external DAC/AMP connected by USB or motherboard audio. HDMI outputs on modern GPUs do not support anything higher than 48000.

In /etc/pulse/daemon.conf add: default-sample-format = s32le default-sample-rate = 96000.

You can change that in /etc/pulse/default.conf ( alternate-sample-rate = 96000, default-sample-format=s24-32le ). This will lead to greater CPU usage, though. This is a bit of a silly situation, having to apply global configuration for all devices. We're planning to add per-device configuration at some point.
