Thanks, I see the drivers for both TDA18271HDC2 and TDA8290 loaded. I thought TDA18271HDC2 was the digital channel decoder, isn't it? Is the "digital channel decoder" different from the digital tuner?? Should be looking for a different chip?
Based on these to chips, I added my card in saa7134_tda8290_callback to call saa7134_tda8290_18271_callback and here is the output of my dmesg: [ 828.879454] dvb_init() allocating 1 frontend [ 829.180234] nxt200x: nxt200x_readbytes: i2c read error (addr 0x0a, err == -5) [ 829.180244] Unknown/Unsupported NXT chip: 00 00 00 00 00 [ 829.180542] saa7133[0]/dvb: frontend initialization failed Hooman On Wed, Nov 24, 2010 at 7:21 PM, hermann pitton <hermann-pit...@arcor.de> wrote: > > Hi, > > Am Dienstag, den 23.11.2010, 17:34 -0500 schrieb Hooman B.: >> Hello! >> I've been trying to get the ATSC tuner in my KWorld PC120-U PCI Hybrid >> ATSC (17de:a134) >> to work with the latest v4l drivers from source (in Ubuntu). >> >> Right now, everything [capture, analog, radio, even IR] works - except >> the ATSC tuner (there is no >> front-end device).
