Hmm, I'm having trouble reproducing this (for now I'm trying with my patched 
PA 4.0 with soxr-vhq). In Foobar2000 1.2.9 on wine 1.6.2 I can only select 
"Primary Sound Driver" or "Pulseaudio" as the output, in both cases I cannot 
select the output format - it says that output format will be chosen 
automatically for the selected device. 'pactl list sink-inputs' says the 
signal sample rate is 44100 Hz. I tried to add resampler to 48 kHz in the 
Foobar2000 DSP pipeline, but the result is the same. In any case, the sound 
plays flawlessly.

Are there any specific settings I should do to reproduce the problem?
