OK.
In order to get the right tuning values from v4l2-ctl --all:

Tuner:

I patched as follows:

if (IOCTL(video_fd, VIDIOC_S_FREQUENCY, &vf) != 0)
{
log(0, "Error tuning to %d: %s", freq, strerror(errno));
and my channels.conf looks like this:
Radio Classic Hits:90000000:C0:C:0:0:300:305:A1:12003:1:1006:0
It's tuning ok now - but I still get no audio.
I'm struggling with this. I somehow need the plugin/VDR to listen to
effectively tune and then do an equivalent of:
aplay -f dat < /dev/video24
how do I do this??
