The majority of the NetBSD developers I've discussed this with are unfortunate enough to have Conexant codecs. I've only done the driver work for our auich (ICH audio driver), since I don't have any of the other hardware handy. One of our developers has a Silicon Labs codec, and he's able to take his modem off-hook and read/write audio without a problem. > Some data sheets are here ftp://ftp.alsa-project.org/pub/datasheets/conex= ant, > but it is unclear (for me) how to hook-off line.

I've looked at the SmartMC II datasheet -- it doesn't even document the EXT_MODEM_CTRL register! From what I've read about Conexant HSF modems, it looks like the majority of them need firmware to be loaded before they're usable; I don't see any documentation on how to do this in the AC-Link version, but I wouldn't be suprised if this was the case. I'm unfortunate enough to have a CXT codec in my laptop (Dell Latitude D600= ): auich1 at pci0 dev 31 function 6: i82801DB (ICH4) AC-97 Modem auich1: interrupting at irq 11 auich1: ac97: Conexant D480 MDC V.92 Modem codec; no 3D stereo auich1: ac97: ext mid 4001, secondary codec auich1: codec not responding, status=3D0xff00 I've had reports that the NetBSD driver is now talking to non-Conexant codecs just fine. Since I can't power on my Conexant codec, I can't test this. Once I get this working, I can finally continue my work on porting slmodem to the NetBSD audio subsystem. Thanks!
