audiomixer related problem under gst-launch-1.0

I am testing some audio-only mixing and streaming functionality using
gst-launch-1.0. In general, audio is taken from a local alsa source,
deinterleaved, then some mixing of channels occurs, these are
re-interleaved, and then sent out as RTP over UDP. In the example I will use
below, I am mixing two input channels to create:
   a channel that is the sum of the two,  e.g. CH0+CH1
   a channel that is the difference of the two: e.g. CH1-CH0
The pipeline looks like this:

PIPELINE:
gst-launch-1.0 -vm alsasrc device='dsnoop:CARD=Loopback,DEV=1' !
audioconvert ! audio/x-raw,format=S16LE ! deinterleave name=input interleave
name=client0_output ! audioconvert ! rtpL16pay ! udpsink host=127.0.0.1
port=16384 input.src_1 ! tee name=input_ch1 input.src_0 ! tee name=input_ch0
audiomixer name=client0_mixer0 ! client0_output.sink_0 input_ch0. ! queue !
audioconvert ! client0_mixer0. input_ch1. ! queue ! audioconvert !
client0_mixer0. audiomixer name=client0_mixer1 ! client0_output.sink_1
input_ch0. ! queue ! audioconvert ! client0_mixer1. input_ch1. ! queue !
audioconvert ! audioamplify amplification=-1.0 ! client0_mixer1.

Breaking down the pipeline for clarity, it includes:
Get input and deinterleave:
   gst-launch-1.0 -vm alsasrc device='dsnoop:CARD=Loopback,DEV=1' !
audioconvert ! audio/x-raw,format=S16LE ! deinterleave name=input
Interleave, payload, and send:
   interleave name=client0_output ! audioconvert ! rtpL16pay ! udpsink
host=127.0.0.1 port=16384
tee-ing deinterleaved channels:
   input.src_1 ! tee name=input_ch1
   input.src_0 ! tee name=input_ch0
Creating the necessary mixers and connecting to interleave:
   audiomixer name=client0_mixer0 ! client0_output.sink_0
   audiomixer name=client0_mixer1 ! client0_output.sink_1
Assigning deinterleaved and teed input channels to mixer inputs.
   input_ch0. ! queue ! audioconvert ! client0_mixer0.
   input_ch1. ! queue ! audioconvert ! client0_mixer0.
   input_ch0. ! queue ! audioconvert ! client0_mixer1.
   input_ch1. ! queue ! audioconvert ! audioamplify amplification=-1.0 !
client0_mixer1.

PROBLEM DESCRIPTION:
What happens is either no audio at all, or audio for a fraction of a second
and then nothing. I see no errors in the debug output (see below). 
When I replace audiomixer with adder, the pipeline works perfectly. 
I have tried including some queues after audiomixer, but I was trying lots
of different of things so I cannot accurately recall exactly what I did.

I would prefer using audiomixer. I plan to extend a similar use in which
zero or more elements will be added into the deinterleaved channels, and
this might create some latency differences among channels (or that is my
fear, so I was hoping to use audiomixer). 

How should I modify this pipeline to make audiomixer work? Any advice is
appreciated.
