The problem is primarily with h/w manufacturers not releasing details on
their products as Rick, K9AO, has pointed out on recent postings. Some
never do, and others only after they think that there is no proprietary
interests that might be revealed. That happens when someone else has
built a better mouse trap and their product is no longer selling. Many
volunteer Linux programmers try to reverse engineer the hardware and/or
the Windows drivers. That is a very difficult endeavor and also fraught
with the possibility of litigation. So they usually do the best they
can with generic i/o for the those devices.

There are many such lists. One of the better ones can be found here:
It might not be up-to-date with the latest gizmo, especially audio
cards. The manufacturer's of audio cards are in steep competition for
the audiophile and gaming market place.
You're trying to use your system for amateur radio. Why not go with a
piece of audio i/o that is designed for that purpose? I just looked
through my December 2007 copy of QST and noted several advertised. Two
that caught my eye are:
page 106, Navigator, www.usinterface.com
page 128, SignaLink USB, www.tigertronics.com
Either might be a good hint for a Christmas present.
I own and test the programs on both a SignaLink USB (no sound card
required) and a SignaLink SL-1+ (requires a computer sound card). The
SL-USB works fine on all of my test computers including an older HP
Some of the alpha test team have reported good results with a very
inexpensive USB audio codec. I won't reveal who first tried it, but he
has been in amateur radio for many years and a particularly strong
advocate for psk and other digital modes.

doesn't meet your needs.
