For a long time I have been using pulseaudio with the resample method set to
src-sinc-best-quality due to the horrible sound quality I have experienced with
the default settings. In my case I listen to a lot of music with good
headphones and a good DAC using high-bitrate flac source material (i.e. 24-bit,
96/192KHz). I found a very significant loss of audio quality when some source
material went through the default speex resampler and found that using
libsamplerate's best quality sounded significantly better than speex at the
cost of higher latency, which I can certainly live with when listening to
music.

In order to get around the lack of libsamplerate support I have been compiling
my own version of pulseaudio but I would like for the support (though
deprecated) to still be supported.

Additionally, I would like to see support in Yast to choose higher audio
quality settings. It took me quite a while to figure out how to configure both
Alsa and Pulseaudio to support 24-bit audio and 96KHz which is what my DAC
supports. I don't notice the CPU usage with the highest quality sample rate
adjustment on my main computer, though on a Raspberry Pi the overhead is
significant.
