default-sample-rate = 44100 alternate-sample-rate = 16000 and/or. avoid-resampling = yes if you have pulseaudio version >= 11. In Pulseaudio 13 there may be even more options, see here. I think it is good to make a bug report about this issue and link it in a comment.

By default, PulseAudio (PA) uses very conservative settings. This will work fine for most audio media as you will most likely have 44,100Hz sample rate files. However, if you have higher sample rate recordings it is recommended that you increase the sample rate that PA uses. In /etc/pulse/daemon.conf add: default-sample-format = s32le default-sample-rate = 96000.

Currently, PulseAudio runs all your devices at a default sample rate, which is set to 44.1 kHz on most systems (this can be configured). All streams running at different sample rates are resampled to this sample rate.

PulseAudio will up or down-mix the source audio to the set sample-rate and then up or down-mix to the sound cards highest supported sample-rate. This means that if you set default-sample-rate to 96000 and you play 44.1 kHz on a sound card with a 48 kHz limit the audio gets up-mixed to 96 kHz and then down-mixed to 48 kHz.
PulseAudio: Sample Format Specifications

Sample Rates. PulseAudio supports any sample rate between 1 Hz and 192000 Hz. There is no point trying to exceed the sample rate of the output device though as the signal will only get downsampled, consuming CPU on the machine running the server. Channels. PulseAudio supports up to 32 individual channels.

default-sample-format = s24le default-sample-rate = 44100 alternate-sample-rate = 48000 ;new with pulseaudio 11 avoid-resampling = true resample-method = speex-float-5 Some remark: This will actively make passthrough non working , as we need s16le format for adding ac3 / dts / etc. to the sink.
