This writes 0x16 to register 0, 0x70 to register 1 and 0x4b to register 2 of the TDA9887. These values correspond to the values programmed for V4L2_STD_SECAM_DK with automatically muted FM audio and both ports set to active.

Try loading the tda9887 module with port1=0 port2=0

Thing is, i don't have tda9887 loaded at all.

tda9887.o is linked into tuner.ko.

Oh. Can i still pass module paramteres to it?

And what does "25 62 8e 04 b0" do?

Uhm, 25 62: 0x2562 should be the frequency+38.9MHz in 1/16 MHz steps Did you tune channel 32 (559.25MHz)?

Actually it sets the channel to ~447 Mhz. I don't quite get the question.

8e: probably frequency granularity, ...
same value as in tuner-types.c:tuner_lg_new_tapc_ranges

04: the frequency band
tuner-types.c:tuner_lg_new_tapc_ranges contains only 01, 02 and 08
LG Innotek TAPE NTSC tuners use 04 for frequencies above 442MHz.

0b: ?

Can you take a look inside to see which tuner is in there?

Nope, there are no visible screws and i'd rather not crack the box open to figure that out.


I have written small program that pushes those two messages via libusb

Do you really need both of them? Try a SECAM channel below 450MHz and send only the 00 16 70 4b.

Yes, i do need both of them for SECAM channels, without first one the
picture is grainy. Plus all SECAM channels(strangely, except the one referenced above) are above 450Mhz.
