I was looking at a log, and noticed the following lines: I [pulseaudio] svolume_mmx.c: Initialising MMX optimized functions. I [pulseaudio] remap_mmx.c: Initialising MMX optimized remappers. I [pulseaudio] svolume_sse.c: Initialising SSE2 optimized functions. I [pulseaudio] remap_sse.c: Initialising SSE2 optimized remappers. I [pulseaudio] sconv_sse.c: Initialising SSE2 optimized conversions. It seemed odd that some messages were somewhat precise in what functionality was initialized, while the svolume messages told me that they had initialized just "functions". So I made the svolume log messages more precise to match the sconv and remap messages.
