PulseAudio uses a high quality resampling algorithm by default. ALSA supports only one, a simple linear resampler. If, like most people, you can’t hear a difference anyways, you can configure PulseAudio to use a linear algorithm too by adding “resample-method = src-linear” in /etc/pulse/daemon.conf. CPU usage will drop from 10% to 1%!

Setting this to false makes PulseAudio use the default-sample-rate even if it means re-sampling 441000 audio. This is the better choice you will be playing audio from different sources - and you will end up doing that from time to time. resample-method sets the type of technology used for resampling. speex-float is a good option for weaker ...

resample-method= The resampling algorithm to use. Use one of src-sinc-best-quality, src-sinc-medium-quality, src-sinc-fastest, src-zero-order-hold, src-linear, trivial, speex-float-N, speex-fixed-N, ffmpeg, soxr-mq, soxr-hq, soxr-vhq. See the documentation of libsamplerate and speex for explanations of the different src- and speex- methods, respectively.
