resample-method sets the type of technology used for resampling. speex-float is a good option for weaker processors. It has many quality/speed options you can use by adding a -number to it. speex-float-10 provides better quality than say speex-float-2 - higher values produce better quality and consume more CPU, lower values have lower quality and consume less CPU.

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 Enhancements PulseAudio could be enhanced to make some of this a bit easier. It could open a channel for each sample rate to provide bit-perfect playback of any sample of audio media.
