[RTTY] "sound on board"

[DJ3IW Goetz]

Hello friends of the digital modes!
It's about time to retire my workhorse Pentium 200MMX and get
something (much) faster. I noted that all of those new machines
have "sound on board", with only three sockets for external
connections. My present Soundblaster AWE64 has four, line-in,
mic-in, line-out, speaker.
How do you use those three on the new boards and what are your
experiences with these on board sound systems? Is there an equivalent
for line-in?
