All the buttons should look very much alike. Convert your scope 
capture to a binary string. There are two distinct time periods. The 
second capture shown would be:

1000100000000111

Do this for the other buttons, and you will send they are all distinct.

Remember that a sound card is limited to ~20 kHz, no matter what it's 
sampling rate. Good enough for a demodulated IR signal, but too 
little bandwidth to see the carrier accurately.
