[KLUG Members] Full duplex sound in core kernel?

[Adam Tauno Williams]

Anyone know a site that lists what sound cards are supported full duplex by the
"stock" kernel?  I have the $20 OSS modules but I need a card(s) that can
support FD with a monolothic kernel (an LTSP station, to be specific).

Currently I have stock SoundBlaster support in my LTSP kernels and via ESD
(ESPEAKER/esddsp) each gets it's own audio stream over the network although the
apps generating the audio (MP3, real audio, games, etc...) are running in the
closet.  I can also record audio from the client's mic,  but I can't (obviously)
record and play at the same time with a half-duplex card,  and the FD-simulation
techniques don't work when you add the latency of ethernet.

The reason I'm going to want FD soon is ***very*** cool.  I've learned that a
PCI/FXO card designed for Linux will hit the streets in the next month or two, 
and for only $99.  This will let me turn a Linux box into a full function PBX
(voice mail, intercom, hold, park, transfer, etc...) and I can drop kick my
"black box" voice mail thingy into the next county.  For stations (handsets) I
can use any IAX client, but they all require FD (obviously).  The same company
is going to release a PCI/FXS card for Linux shortly following the PCI/FXO card
but haven't made a specific statement about features or pricing.
