[linux-dvb] Hi, hauppauge win tv Nova-s plus won't tune

[Roland HAMON]

Hi

(I'm new to the list, hope I won't infringe any rule on my first post)

I have a hauppauge win tv nova-s plus PCI card, connected to a simple
dish wich is pointed to hotbird3. Under windows wintv works fine: I get
160+ free to air tv channels as expected.

Under ubuntu intrepid 64 bits (2.6.27 kernel) vdr fails to tune any
channel. I tried dvb-apps 'scan' with no success:

scanning Hotbird-13.0E
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
initial transponder 12539000 H 27500000 3

femon -H gives 60% signal and 40% snr. (quite bad!)
Then when I poweroff my computer hangs and the motherboards beeps
repeatedly until I hard swith it off.

Any help greatly appreciated.
(btw, http://bugzilla.kernel.org/show_bug.cgi?id=9476 ...
 I might be having the same bug but I did not try any previous kernel
version with this card)

Bye

There is a bug in the cx24123 driver.  It does not generate the 22KHz
tone for high-band.  This seems to date back to changeset 4012.  This
removed the code which used the ISL6421 tone generator.  I presume the
intention was to transfer this function to the isl6421 module, but
this wasn't done.  I tested this with a function as follows:

static int isl6421_set_tone(struct dvb_frontend* fe, fe_sec_tone_mode_t tone)
{
	struct isl6421 *isl6421 = (struct isl6421 *) fe->sec_priv;
	struct i2c_msg msg = {	.addr = isl6421->i2c_addr, .flags = 0,
				.buf = &isl6421->config,
				.len = sizeof(isl6421->config) };

	switch (tone) {
	case SEC_TONE_ON:
		isl6421->config |= ISL6421_ENT1;
		break;
	case SEC_TONE_OFF:
		isl6421->config &= ~ISL6421_ENT1;
		break;
	default:
		return -EINVAL;
	}

	isl6421->config |= isl6421->override_or;
	isl6421->config &= isl6421->override_and;

	return (i2c_transfer(isl6421->i2c, &msg, 1) == 1) ? 0 : -EIO;
}

and added it to the override ops.  This works fine for me and I am now
getting lock on high-band transponders, but it is probably just the
easy part as I have no idea how DiSEqC Encoding should be handled, nor
how to manage overrides for other cards which use this driver, but may
not want it to generate tones.

Roland, if your low-band transponders are also failing, that is another
issue!

This is a known bug in latest Ubuntu release and not related to DVB.
