Also, with PulseAudio forced to 44.1 kHz, FooBar2000 v1.2 (which uses
DirectSound and thus, by default, resamples everything to 48 kHz) just

over soxr-vhq and works fine over speex-float-5. soxr-hq and soxr-mq
also work fine with wine.
I didn't quite understand this test, could you elaborate? Are you
running Windows in a VM here? Which one?
That's in wine. FooBar2000 v1.2 (and not any later version) is good for
testing DirectSound-related code paths.
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?
Well, I guess this is a left-over from my experimenting with the
unpatched alsa output module. And your distribution applies the
non-upstream "pulseaudio output" patch.
So, please add this registry entry to reproduce the test result:
[HKEY_CURRENT_USER\Software\Wine\Drivers]
"Audio"="alsa"
regedit alsa.reg
But it still boils down to a low-latency stream.
