Hmm, -ge:0,0 should work. There are too possible problems:

1) the input samples before actual audio data are not
    zeros ... you could try with -ge:0.1,0 instead and see if it
    works better

2) -ge is block based (= not sample-accurate), so when the gate
    opens, all the samples inside that block are passed through...
    you can use the -b:xxx option to set the blocksize => with
    a really small blocksize like -b:16 the worst-case error
    is just a couple of samples

PS It is not impossible to make -ge sample-accurate, but
    can't promise you anything about the implementation schedule.
