[linux-dvb] LifeView FlyDVB-T using saa7134 - "tuning failed"

[David Stevenson]

Hi all,

I am having problems setting this card which I purchased recently after looking at the supported list for DVB-T hardware. I wondered if anyone here could point me in the direction as I seem to be meandering in the dark, so here goes...

I am using Ubuntu 6.10 with kernel 2.6.17-10-generic, the machine is 32bit and uses a NVidia dual head graphics card (not sure if that last piece is important).

My aerial supply's a signal to a DigiFusion digi box which sits next to the PC (until I get the FlyDVB working) and receives a great signal. Aerial is pointing (visual line of sight) towards uk-Mendip (distance ~15 miles).

My symptoms are simply that using 'scan' - I cannot tune any channels using:

% scan /usr/share/doc/dvb-utils/examples/scan/dvb-t/uk-Mendip

scanning /usr/share/doc/dvb-utils/examples/scan/dvb-t/uk-Mendip
using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'

Here is my dmesg output:

When I do try to scan, this gets logged:

Jan 17 11:24:45 dtop1 kernel: [17230346.380000] tda1004x: setting up plls for 48MHz sampling clock
Jan 17 11:24:47 dtop1 kernel: [17230348.328000] tda1004x: found firmware revision 23 -- ok

I tried to run the get_firmware to see if I could update it, I downloaded and installed into /lib/firmware/2.6.17-10-generic rmmod the modules and re-modprobed:

rmmod saa7134-dvb && rmmod saa7134_alsa && sudo rmmod saa7134
modprobe saa7134_dvb

and still no difference in version number.

I have searched the Ubuntu and LinuxTV forums/mail list archives but having found many posts/guides etc I feel I must be missing something obvious.

Can anyone help me see the light?

Much appreciated for your helpful and informative website!
David.
