Unable to play and record Internet stream at the same time

[Michael MacIntosh]

You could try adding a queue to each of your branches, since the 
lamemp3enc might have a very small buffer, (or playbin), you will need 
to have a small amount so it can play and record at the same time.  By 
default gstreamer will try to synchronize all sinks such that they 
"play" the same sample at the same time.

So you could try something like this (bolded the added queues for clarity):

$ gst-launch-1.0 souphttpsrc location=<livestream url> ! decodebin !
audioconvert ! tee name=t*! queue*  ! playsink t.*! queue*  ! lamemp3enc ! id3v2mux ! filesink
location=test.mp3

Hope that helps!
