Hi all,

i am trying to set up a multicast machine and am having a problem with
multicasting audio.  i can put audio packets on the wire, but it
sounds like jet engine noise.

i seem to have all my devices made properly, and i can play sounds,
mp3s , record from microphone to a file, play the file back etc...  i
tried a mess of soundcards with similar results.  right now i'm using
a PCI guillemot card:

  myhost# uname -a
  FreeBSD myhost.ai.mit.edu 4.1-RELEASE FreeBSD 4.1-RELEASE #0: Mon Oct
  2 15:43:21 EDT 2000 root@myhost.ai.mit.edu:/usr/src/sys/compile/AI
  i386

  myhost# cat /dev/sndstat 
  FreeBSD Audio Driver (newpcm) Oct  2 2000 15:42:52
  Installed devices:
  pcm0: <Yamaha DS-1E (YMF744)> at memory 0xfaff0000 irq 14 (4p/2r channels duplex)

this is in my kernel config file:

  device          pcm0
  device          sbc0

i'm using vat v4.0b1.  i also tried rat4.0.4, but that doesn't even
register input.

vat spews this as well:

  myhost# ./vat -t 1 -n -f pcm 239.2.2.2/20000

  Oct 13 09:50:44 myhost /kernel: overrun, dumping 172 bytes
  Oct 13 09:50:45 myhost /kernel: overrun, dumping 168 bytes
  Oct 13 09:50:45 myhost /kernel: overrun, dumping 168 bytes
  Oct 13 09:50:45 myhost /kernel: overrun, dumping 172 bytes

any thought would be muchly appreciated.
michael
