Public bug reported:
as described by user Kirill Kabardin on 2012-08-13 in question:
https://answers.launchpad.net/ubuntu/+source/pulseaudio/+question/205700
I can't get pulseaudio to play at 96000 hz sample rate. It worked in 11.10
I have this options enabled in /etc/pulse/daemon.conf (some of them were
enabled by default, I only changed that ones that marked with #):
resample-method = ffmpeg #
enable-remixing = yes #
enable-lfe-remixing = yes #
flat-volumes = no
default-sample-format = s16le #
default-sample-rate = 96000 #
default-fragments = 8
default-fragment-size-msec = 10
deferred-volume-safety-margin-usec = 1
I have this messages in "pulseaudio -v" output (this is not a full log, it just
too big to put here):

It says that device does not suppport 96000 Hz but it definitely does. I can
play 96000 khz 16-bit audio files just fine with aplay:
