cheap pci sound card with full duplex support?

cheap pci sound card with full duplex support?

[Roland Dreier]

I would like to get a sound card that can do full duplex under linux (ie
open /dev/dsp with mode O_RDWR).  I see cards like the "Ensoniq AudioPCI"
for around 20 bucks that claim to do full duplex, but I don't know whether
there's a linux driver.

So, my question: are there sound cards (preferably PCI) for around $20
that have full duplex support under linux?  Are the drivers free?

Thanks,
Roland

Ensoniq AudioPCI is supported in kernel 2.2.x.
It may also work under 2.0.x with the ALSA drivers ( http://alsa.jcu.cz )

I have a Soundblaster 64 PCI ( which is actually an Ensoniq AudioPCI 
with a soudblaster sticker on it ) and it works under linux 2.2.1.

Wave out and mixer works , haven't tested the rest.
Its a cool card , which support 4 channel sound ! 

But also  have a cosmetic bug - in order to record a sound, you must
set it to play ( hear it on the output of your card ),
the microphone is an exception, otherwise it would be unusable.

This way you can't play a sound and record it back from AUX-in using a cable to
connet ( LINE-out and AUX-in ) , for example to test the characteristics of
the card ...

I think it should be sufficient to enable a channel as recording source
but turn its volume down to 0. But this is indeed on a list to
rethink 8-)

No , this way you will record silence, because the play volume of a channel is
also its record volume :-(
You record what you hear...

Hi

How good is the quality of this card, compared to cs4231a chip? (From
/dev/sndstat, I haven't actually looked at the chip on the card. ) I
currently have a problem using full duplex when there is ide disk
activity. I have to kill update to make it work, which is probably a bad
idea? I have a via chipset. 

What is the best quality card (I don't care about wave table stuff, just
dac/adc and full duplex)which will work with linux? Preferably with a free
driver.

Regards
