Hi,
I have a little application that just records to disk from a
soundcard at whatever bit rate, number of channels and resolution
bits that you tell it. This has been working fine for years on
FreeBSD.
I have been using Luigi's sound stuff recently. I *think* that
the program ran ok on FreeBSD 3.X with Luigi's code.
I tried it recently on 4.2-RELEASE and came up with ioctl errors.
Here's an example chunk of code that causes the error..
parm = atoi(argv[1]);
if (ioctl(dspfd, SOUND_PCM_WRITE_BITS, &parm)) {
perror("ioctlwrbits");
exit(1);
}
In this case "parm" is 44100, or whatever bit rate you're using to record.
I read soundcard.h and it looks like this set of ioctls is not valid
for Luigi's code. I had thought it was "backward compatable". No?
