[linux-dvb] TT T-1500

Should I get any type of tuner message from the TT-1500, should the
tda1004x driver detect and handle the TD1316 tuner module??????  Is this
what I am missing....since I guess on cards with the TU1216 it's all
build in, the TD1316 has to be paired explicit with the TDA...?????????

Yes, I have tried the jumper on and off, thanks for the tip.  It made no
difference.  I've tried pretty much everything, even debugging messages
in the tda1004x module, which shows successful i2c comms both ways.

I'm assuming I'll get no tuner messages in the kernel output, just the
tda1004x frontend messages, as it is this that handles the tuner.

Nick,

did you check the jumper that's on the TT-1500 card? I've also got one
and had to remove the jumper to get it to work.. was related to power
injection into the arial.
