I've never actually used my SB16 for recording - anyone here have an
answer for Frank? Thanks!

Greetings,
OK ... I am really foolish and can easily count myself among the
masses that don't read documentation well enough. It turns out I forgot to
change the blah/blah/blah/sound/sound.<something>.h file so that the IRQ
entry in there matched the config file. I changed that and now I get all
the sound output I could have ever wanted .... EXCEPT .... I still don't
know how to record properly. If I try cp /dev/audio test.au or
cp /dev/dsp test.au I get an "Interrupted system call" ... whatever that is
supposed to mean. If I do cp /dev/dsp16 test.au it works and produces a file
but I don't quite know what it is recording but it is most definitely NOT
the audio from line-in or mic. If I play it back through /dev/dsp16 I get
an EXCELLENT reproduction of a 15kHz tone ... AMAZING! It must have used
some truely advanced encoding method to come up with that one! Now, my aim
is not to put anybody down here because audio recording is not CRUCIAL to my
sanity or anything. I think FreeBSD is great and I could not ask for anything
more ... I am just having a bit of fun because it is late (for me) and I am
getting quite sleep and this right eye of mine is really bothering me because
I cannot quite focus it correctly anymore ... Anyway, I suppose my main
question now is ... HOW DO I RECORD?
Frank Ficnar
Oh ya, I was asked last time to include the relevant sections of my
config file so here they are ...
controller snd0
device sb0 at isa? port 0x220 irq 5 drq 1 vector sbintr
device sbxvi0 at isa? drq 5
device sbmidi0 at isa? port 0x330
device opl0 at isa? port 0x388
The IRQ is correct and the DRQ (which I assume is the DMA channel)
is correct in the sb0 entry if that refers to 8-bit. The DRQ for sbxvi0 is
correct if that refers to a 16-bit channel. All the addresses are correct
as well. I also changed the appropriate lines in sound.<something>.h
concerning the IRQ and the DRQ for the assumed 16-bit channel (it used to
read 6.)
MANY, MANY Thanks for your help.
