Hi, I'm trying to setup my HTPC Linux box as HQ/"Audiophile" player. By
default pulseaudio re-samples all played files that don't match default
or alternate sample rate to those rates which is not appreciated in this
scenario.
After some trial and investigation found reason for not working original
patch of high sample rates playback without re-sampling posted here:
https://patchwork.freedesktop.org/patch/124196/
This patch alternates src/pulsecore/source.c, but for successful
implementation src/pulsecore/sink.c need to be patched too.
With this implementation are files with high sample rates played with
their original sample rates without re-sampling if your HW supports
media encoded sample rates.
I've successfully tested 44.1k,48k,88.2k,96k,176.4k and 192k flac files
played with VLC on SundBlasterX G5 DAC.
Regards,
Milan

Hi, I'm interested in your patch to play audio files of high sample
rates without hassle. Have you chance to proceed with maintainer
suggested changes? I've tired your original patch yesterday, but didn't
work for me. May be I miss something. So far I've done:
Git cloned actual pulse-sudio
patched src/pulsecore/source.c
builded and instaled /usr/local/
set default-sample-rate/alternate-sample-ratein /etc/pulse/daemon.conf
Audio is working but the same way as before, e.g only two sample rates
are used directly by DAC, other sample rates are re-sampled to default
sample rate.
Can you help me please? What I'm missing?
Thank you for your help in advance!
Kind regards,
Milan
