My research and experience bears out my initial statement. The current
ice1724HT driver used with the Audiophile 192 results in an "overdriven" and
"distorted" sound output (the ice1724 does'nt work at all). This was
reported to the ALSA Team. The ALSA Team responded with a request for
someone to send them detailed photos of the chipset on the 192 card. I guess
there is some hardware on the 192 card that is different than any of the
other Delta or Audiophile cards.

When I enter the OSS command "./soundon," ALSA is shutdown and gone! When I
look at the mixer "device" options, the only choices are "0: Realtek ALC850
rev 0 (OSS Mixer)" & "1: ICE1724 - multitrack (OSS Mixer)." This is why when
I issue the command "./osstest," I get good clean sound out of the
Audiophile 192 (see previous paragraph on the ice1724HT driver)

Did'nt we all come from the Microsoft camp? ;-) For in the beginning, there
was only Unix. Unix was too expensive to own for home users, and there was
no such thing as a Gnome or KDE GUI! Personally, I started Linux about 13+
years ago, when it was still all done from the dot prompt, and Red Hat

This was my initial guess. I am thinking OSS does not really play well with
GUIs and hickups on Jack. I'm thinking 4Front Technologies meant for the
sound card to be controlled from the dot prompt. I'm wondering if this is a
major reason why most of anything I read or hear about Ardour (or any other
sound app), it is running with ALSA!

Are you running a 64-bit system? Maybe this has something to do with my

You're right. The ice1724 - multitrack device is the Audiophile 192. As I
mentioned in the previous paragraphs, running the osstest command under
usr/lib/oss/bin plays a test audio file that is directed to all the outputs
it finds. The test shows it is accessing the Audiophile 192. The test runs
great! But when I turn on Jack and look for ports or patches to connect,
there are none!

Hey Steve! I'm in NM as well! Let me know if you are near the East Mtns. If
so, you can come over and take a look at the setup yourself!
