[PATCH alsa-lib 0/2] Allow multiple formats for PCM rate plugin

Hi,

this is a patch set for alsa-lib to extend the PCM rate plugin for allowing multiple formats for its converter plugins. This optimizes and improves the quality (skips the unnecessary buffer and conversion) when the converter supports the source and/or the target format natively.

The patches for libswresample and libsamplerate will follow.
