could it be that synaesthesia and your mac audio sink do not share any
compatible format. You have converters before tee. So gst tries to find
a common format for both. Does this work:

gst-launch uridecodebin uri=http://81.88.37.2:8030 ! audioconvert !
audioresample ! tee name=t ! autoaudiosink t. ! queue ! audioconvert !
synaesthesia ! ffmpegcolorspace ! osxvideosink
