--- Comment #26 from Hans Petter Selasky <hselasky@FreeBSD.org> ---
Hi,

I think the problem is that SNDCTL_DSP_SETFMT doesn't have the AFMT_STERO b=
it
set, and this forces the audio to 1-ch mono:

    if (ioctl(fInFD, SNDCTL_DSP_SETFMT, &fSampleFormat) =3D=3D -1) {
        jack_error("JackOSSDriver::OpenInput failed to set format : %s@%i,
errno =3D %d", __FILE__, __LINE__, errno);
        goto error;
    }

Actually you should read the channels first, then SETFMT, then write channe=
ls.

--HPS
