I tried both in different variations, but I keep getting the same
errors. I suspected that the problem might be related to push vs pull
mode, but unfortunately adding the queue2 element didn't fix it.

I tried this, and it works for FLAC:

$ gst-launch-1.0 playbin3 ring-buffer-max-size=5242880 audio-sink=pulsesink uri='http://www.lindberg.no/hires/test/2L-056_04_stereo-44kHz-16b.flac'

It does not work for DSD from the same server:

$ gst-launch-1.0 playbin3 ring-buffer-max-size=5242880 audio-sink=pulsesink uri='http://www.lindberg.no/hires/test/2L-056_04_stereo_DSD64.dsf'

What else can I try? Thank you for your help!
