Very Computer

I am trying to get my audiotool record in linear encoding rather than u-law
which is the default.

Checked the man pages and it tells you to use some ioctls for this job.
I have tried the following code:

        if ((ioctl(fd_audio, AUDIO_GETINFO, &auInfo)) == -1) {
                perror("ERROR: ioctl AUDIO_GETINFO");
                exit(1);
        }

        printf("encoding    = %d\n", auInfo.play.encoding);

        auInfo.record.encoding = 3;   /* 3 = linear encoding */

        if ((ioctl(fd_audio, AUDIO_SETINFO, &auInfo)) == -1) {
                perror("ERROR: ioctl AUDIO_SETINFO");
                exit(1);
        }

        if ((ioctl(fd_audio, AUDIO_GETINFO, &auInfo2)) == -1) {
                perror("ERROR: ioctl AUDIO_GETINFO");
                exit(1);

        printf("encoding    = %d\n", auInfo2.play.encoding);

where both auInfo and auInfo2 are audio_info_t structs. Both of my printfs result in
printing 1 which is u_law encoding.

Any ideas to get this thing record in linear (8-bit) encoding.
Please reply to:

TIA.
