Support for Leadtek DTV1000S ?
Hi,
I am trying to get this card to work as well and I also got the i2c errors from the tda10048 -
but the i2c_debug=1 option of the saa7134 driver points to the following code, which was added
recently I think. Without it the i2c errors stop, the tda10048 and tda18271 attach, and the firmware loads
#diff saa7134-i2c.c.1.1.1.1 saa7134-i2c.c
262a263,271
Quoted 9 lines
if (i > 0 && msgs[i].flags & I2C_M_RD) {
/* workaround for a saa7134 i2c bug
* needed to talk to the mt352 demux
* thanks to pinnacle for the hint */
int quirk = 0xfd;
d1printk(" [%02x quirk]",quirk);
i2c_send_byte(dev,START,quirk);
i2c_recv_byte(dev);
}I am currently trying to get the tda18271 to lock onto a signal but with no luck yet

This is pretty much where I'm at right now. I've been through the tda18271 code and, with the exhaustive use of debug statements, am satisfied that it setting up the tuner correctly. The problem seems to be somewhere between the tuner and the demod or how the demod is interpreting the tuner data.

Do you have any ideas as to what I could try next? I've tried changing the settings in the
tda10048_configandtda18271_configstructures without much luck. Where you able to get any further?Best regards

Hi James,
The signal strength doesnt go low when the antenna is disconnected (it does on my other card) instead it stays high. I am currently looking for some kind of switch between the antenna and the tuner or a gain problem (too sensitive?)
Cheers,
