Ok, well I think I have a decent first run at integrating the fixed point sampler.  Here is the patch. <a href="http://www.foinse-project.org/pulseaudio/libspeex_v1_1.patch">http://www.foinse-project.org/pulseaudio/libspeex_v1_1.patch </a> (mailing list has 40k limit and it is 65k)   It seems to work well and I got my channel doubler working correctly so it should also convert from one to two channels.   I'd like for someone else to try it out for a sanity check.   I'm only using generic fixed point from libspeex so there should be lots of room for speed improvements. You should be able to apply this to the tarball 0.9.5 sources. After building you can run the pulseaudio daemon with the parameters --resample=libspeex:0   where 0 can be 0-10 and represents quality. As for clicking problem I was having before,   I can still sometimes get them when playing through paplay, but not through gst-pulse, weird. Keith Preston
