I always thought you could only set 2 sample rates in pulseaudio. Nope. First of all you want to set default to 44.1 so there is no resampling for regular flacs and cds. Then set alternate to 48 to cover dvd quality. Then set "avoid resampling" to true. If you have a modern dac made in the last 5 years... it will have auto resolution switching.

Alternatively: If you don't want any resampling outside Kodi, e.g. no resampling done extra by pulse, you need to configure the sink as told above and set Audio Engine to Fixed with the number of channels you configured pulseaudio via pavucontrol and samplerate of 96 khz with resample quality high.

Bug 5794 – pulseaudio: resampling 44k1hz mp3 to 48khz ...
https://bugs.maemo.org/show_bug.cgi?id=5794
48khz should show no problem, as no resample would be required. I have couple of 44k1hz files here, from ages, and most of them cause the resampling. Some top output: 745 1 pulse S < 4564 1.8 22.8 /usr/bin/pulseaudio --system --high-pr 745 1 pulse S < 4596 1.8 21.3 /usr/bin/pulseaudio --system --high-pr so not 30% but around 20-25.

Resampling your 44,100Hz media may be an issue with the above settings so you can increase the resampler quality from the PA default. In /etc/pulse/daemon.conf add: resample-method = speex-float-5 For the most geniune resampling at the cost of high CPU usage (even on 2011 CPUs) you can add: resample-method = src-sinc-best-quality

PulseAudio defaults to a low-cpu resample method, but any modern computer should be able to be cranked to the max. Ideally, there isn't any resampling going on anyway, so this setting isn't even used. Step 1: Copy the files in /etc/pulse (there are 4 files in there) to ~/.config/pulse.
