Pinnacle PCTV Pro tuner problem

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]



Hi everyone,

I'm having problems getting a brand new Pinnacle PCTV Pro card to work.
Somewhat more precisely, according to the box it is a PCTVpro GB/D/NL Rev. C.

The PCB is red, and is labelled EMPTYV-51014521-2.2A. It appears to have a
Bt878A, an MSP3410G-B11 and a TDA9887-TS. However, which tuner is present is
hard to tell, as it is protected from interference as well as from visual
inspection by a neat metal shielding soldered onto the PCB.

And this is, unfortunately, very much the problem. Composite video works,
and seems quite promising, but TV and radio just give endless amounts of snow
(and its auditory counterpart). Tuning does not appear to accomplish much, if
anything at all.

I've grepped through the archives of this list, and it appears most people
with a Pinnacle PCTV Pro and tuning problems had an MT2032 tuner. Although
this tuner is also picked by the driver when left to its own devices, it appears
not to be the right choice for this particular card:

tuner: probing bt848 #0 i2c adapter [id=0x10005]
tuner: chip found @ 0xc0
i2c-core.o: client [(tuner unset)] registered to adapter [bt848 #0](pos. 1).
...
tuner: pinnacle pal
tuner: type set to 33 (MT2032 universal)
MT2032: Companycode=3cbf Part=42 Revision=90
MT2032 hexdump:
 42 90 20 c1 00 f7 7e 55  a4 08 85 92 8d 5b f0 00
  24 3c bf 42 90
 not a MT2032.

I've also seen this dump:

MT2032 hexdump:
 42 2f 25 c1 00 63 10 8a  29 04 85 99 e3 b0 f0 0f
  24 3c bf 42 2f
 not a MT2032.

Oddly, although the board does contain a TDA9887, this chip is not seen by
the detect tool (neither is it found by the tda9887 driver probe):

$ ./detect
0x80: msp34xx/tea6300 sound processor
0x96: ???
0xa0: eeprom (bt878, Hauppauge-848)
0xc0: tuner

However, the tvaudio module reports a pic16c54 at address 0x96:

tvaudio: found pic16c54 (PV951) @ 0x96
i2c-core.o: client [pic16c54 (PV951)] registered to adapter [bt848 #0](pos.
2).

I'm using version 0.7.106 of the bttv drivers with kernel 2.4.20. I've tried
all other tuner types just in case (to no avail).

My question: is this actually a known type of card, or is this a new type of
PCTV card not yet supported? If it is known, has anyone succeeded in getting
it to work? Any suggestions, guesses and wild conjectures would be most
welcome in any case.

Thanks,
Eyran
