Can Snapcast handle a sample rate over 48000?

[gnadrian]

I'm getting noise rather than music when I specify a sample rate of 96000:
sampleformat = 96000:32:2
(all other settings are the defaults)
and sending data with ffmpeg:
ffmpeg -y -i audio.flac -f u32le -acodec pcm_s32le -ac 2 -ar 48000 /tmp/snapfifo

If I wind things back to 48000 it works fine.

I get the same noise even with two different client machines, and even when instructing the client to downsample, so it seems to be a transmission problem rather than a playback problem.

Can anyone help?
