I've never used rat (maybe an MBONE expert will chime in with some
help here), but the ktrace output here looks mighty fishy.
First, it's opening /dev/audio (8KHz ULAW device). Then it tries to
change the sample rate...Hmmmmmmm. Looks like it should have opened
/dev/dsp if that's what it wanted to do. That fails of course.
Then it looks like it goes off into LaLa land sending an ioctl and
close to fd -1, following up that act by trying to reopen /dev/audio.
Sorry, only one device at a time there.
Appears rat might not be configured right and could use some fixes to
handle incorrect configuration and error handling. ...that's just my best
guess never having run rat before.
BTW, your device files have the same major and minor as mine, so that
looks OK. Hope this helps.
