One possibility is that MMTTY and the radio are set to different tones. 
Another is that the radio may not be getting keyed. I use VOX, which is 
turned on and off by mode. So if you're using it, check to see that the 
rig is set for VOX in AFSK-A mode. Also check VOX levels.

Another possibility is that your computer sound card has been set to the 
wrong L/R channel. Check the playback mixer for the SignalLink. Also 
check that the RTTY program is using the SignalLink.

The fundamental differences between AFSK-A and DATA-A are that AFSK-A 
uses MMTTY as a single frequency decoder, works LSB, and the dial 
frequency is the Mark frequency. DATA-A uses USB, and uses software with 
multiple decode capability, and the digital modulation can be moved 
anywhere in the passband to the frequency of the signal you've chosen to 
work.  AFSK-A is RTTY ONLY, DATA-A can be used with ANY digital modes.
