Yes, I believe that once you found out the right settings it will work not
worse than a BayCom. But until you are at this stage, it is a very long and
stony way to go....

According to Thomas Sailer, there is a problem of those drivers not being
capable of switching from playback to record/sample mode fast enough.
It may also be not very easy to get FSK RX/TX filters as well as other signal
processing "goodies" working with them.
At least those were the reasons for Thomas Sailer why he decided to write a
separate SoundModem driver.
