Perhaps -> someone else on the list saved the diffs last time they got posted?... Turns out that I had an SMC card laying around in the networks lab, so I just swapped it in, and the ed0 device works like a champ. Thanks for the note, though. Unfortunately, one of the other things I said in that message: -> >I'm trying to get a FreeBSD box (2.1.0-SNAP) running some of the MBONE -> >tools. (sd, vat, nv, etc) It doesn't seem to want to do it, though. is still true, even with multicast stuff working fine. vat is now a pinprick in my posterior, the others work fine. If someone has vat running succesfully on a pentium, I'd love to hear about the configuration and what hardware you're using. If you want to see the long details and maybe help me debug this mess, read on. Otherwise, you can stop here. To get vat to work, I've done the following: - rebuilt the kernel with SoundBlaster support - made all the /dev/snd* and /dev/vatio devices - downloaded vat from ee.lbl.gov I'm using a simple, old 8-bit SoundBlaster, and I've got the kernel drivers configured fine (I think). If I run the voxware au server and audemo programs, I get a lot of messages "/kernel: PCM device 1 not installed", but it works otherwise. To actually use it I have to do all this: - fire up the voxware au server - fire up "audemo" and go to record mode. - activate the mic. - shutdown all the voxware programs. Then I can run vat and it will transmit fine. If I try to receive, I get a brief blast of static on the speakers, and then all is dead. vat still runs, but it never sends or receives another sound. When I quit it, I get a ps report something like this: paco 186 0.0 3.4 856 624 p3 SE 11:14PM 0:00.54 vat It is sleeping and trying to exit. (the SE in the status column). It never exits. Any subsequent vat's that I run will turn into zombies when they exit. Nothing is ever able to use the sound drivers again. Not the voxware stuff, not vat. I'm utterly stumped and this is holding up my research pretty badly. I graciously appreciate anyone who can help me out with this. Heck, if you want, I'll give you a 236Mb SCSI hard drive for solving this problem. I'm desperately seeking help. Thanks!
