Wait can give the PSTN/TDM world a chance to settle before proceeding with 
your dialplan. Your wording implies that you need wait() as follows:

 	exten = 202,1,		answer
 	exten = 202,n,		wait(1)
 	exten = 202,n,		playback(tt-monkeys)
 	exten = 202,n,		wait(1)
 	exten = 202,n,		playback(demo-congrats)
 	exten = 202,n,		hangup

Which is probably not true. It's probably more accurate to say "I need 
wait() after every answer."

You only need a sound card if you are using Asterisk console commands like 
dial. Note this is different than "dialplan applications like dial."
