this might not be the right group..but hey..
i have a TV card installed but can't get suitable drivers for it..
not sure what it is..but it's got a philips BT848 chip..
i want to use this to watch normal TV and use the composit socket for an 
external receiver unit..
i am using the older hauppauge drivers but the sound is buzzing..and the 
composit nearly has a signal..
i have tried mixing and matching drivers but no perfect match yet..

any suggestions ??..or group thats more suited ??

I seem to be in sound card hell.   My machine's on-board audio is
fixed at a 48KHz sample rate and I don't want to do re-sampling in
software.   I scrounged a sound card out of another machine and found
it to be a undocumented OEM version of the SBLive! for Gateway computers.
It's just different enough from the standard version that it plays, but
will only record silence.

Since it looks like I'll have to buy something I'm wondering... what's
a good PCI sound card for ham use?   Comments?

You could try to do a search on the FCC ID code, so you can find out who the 
manufacturer is and what the product is. After that it will be easier to 
locate a driver.

The 16-bit SoundBlaster PCI works best ( for me ) with the largest variety 
of Ham Radio software.

So far I've found info on about 11 different cards that all call
themselves SBLive!  None of the info describes the custom OEM version
made for Gateway, the one that has different jacks on the back.

Yep, probably just a simple matter of programming.  But since the card
is undocumented it makes the programming choices a bit harder.  I suppose
I could spend the next several months toggling toggling bits at random
in hope that I stumble on the right combination.   Or I can buy anyother
audio card.

Got any suggestions on a good card for ham use?

Get the generic SBLive! installer from Creative's web site.
When you install it, make sure you install SB16 emulation.
This works for Windows. For Linux you may need to check
that the specific CTxxxx number has support.

Details on the different cards can often be found via
a Google of their CTxxxx number.

I've picked up a number of the older "SBLive! Gamer Value"
variety on eBay, generally for about $10 - $12. These are pretty
generic versions of the Live!, and have the four jacks instead of 3.
Was going to check CT number, but all are in computers right now.
CT4670 or 4560 sounds kinda familiar.

Perhaps if I had a windows partition on this box, but I don't.
Apparently Gateway has a windows driver for this specific card, too.

Yep.  My card is the CT4830 which apparently some software reports
as a CT4832.  The Gateway version of this card removed the S/PDIF
output jack and multiplexed it onto the line out 1 jack with some
(undocumented) way to switch between audio and digital output.
I got around that by using the line out 2 jack.   Play works just
fine.

But recording gives me silence.   I suspect there's an internal mapping
in the the EMU-10K1 that isn't being set correctly by the *BSD driver.
I get silence on line in and mic in.   It's a digital interface issue
as the mixer is more than happy to route mic and/or line in to my
line out.

That's an idea.  I've also been told that older Ensoniq PCI audio
cards will work well in my environment.  I guess it's ebay time.
I'm tired of looking at audio driver code and guessing what the
relevant bits may be.

Thanks,

Any generic SBLive will do you well, and they're cheap.  I've gotten
several locally for $5/each, and all of my computers have one.
They're excellent cards, and while I don't know what the deal is with
the OEM version you have, it's not worth wasting much time on.

As an added bonus, I don't know about the BSD driver, but the Linux
drivers can play multiple streams at once on the card without a
software mixer like esd.  This doesn't sound like a big deal, but it
is -- you can be playing music, and it can play a new mail sound at
the same time.  Or you can fire off six different xmms programs, and
play six different songs at once.  It's very nice, and it's why I
don't deal with anything but SBlives anymore.

Not wasting time is good!   A cheap SBLive or SB16 is what I'll
look for.   I'll save my current card for the next windows machine
I build, i.e. religate it to the junk pile :-)

Thanks to all for your input,
