 |
|
Hi guys!
A few days ago I got a Snazzi brand TV card (PCI) with a SAA7134
chip. I chose this one because I saw a list of TV cards with several
people reporting that this chip worked "out of the box" for them on
OpenSuSE 11.0 and also because it has two composite video inputs and
two stereo audio inputs.
I put this card into my computer and when I rebooted went to Yast and
saw that OpenSuSE had found the card and recognized it. For its
configuration I just clicked on "Next" several times and didn't get
any errors, except when it tried to find the TV channels -this card
doesn't have a built-in tuner.
The problem is that I cannot get any video nor sound. I tried with
kdetv and motv, and with both I just get a black screen and no sound
when I set the source as "input = default" in motiv or "source
default" in kdetv.
If I do from the command line: >motv -hwscan
I get: ...
/dev/video0: OK [ -device /dev/video0 ]
type : v4l2 ...
If I do from the command line: >lspci
I get: ...
05:09.0 Multimedia controller: Philips Semiconductors SAA7134/
SAA7135HL Video Broadcast Decoder (rev 01)
But if I do: > dmesg | grep 7134
I don't get anything. I think this last part is very suspicious.
I have no previous experience with TV cards. I will greatly
appreciate any advice.
Thanks,
Andy |

Hi EOS,
I appreciate your quick response. Yes, I think the module is
installed. If I do lsmod | grep 7134 I get all of the following:
saa7134 141140 0
videodev 35712 1 saa7134
compat_ioctl32 5376 1 saa7134
v4l2_common 15488 1 saa7134
videobuf_dma_sg 18436 1 saa7134
videobuf_core 23172 2 saa7134,videobuf_dma_sg
ir_kbd_i2c 14096 1 saa7134
ir_common 41476 2 saa7134,ir_kbd_i2c
tveeprom 19088 1 saa7134
i2c_core 28820 6
saa7134,v4l2_common,ir_kbd_i2c,tveeprom,i2c_i810,i2c_algo_bit
I even added saa7134 to the MODULES_LOADED_ON_BOOT variable in /etc/
sysconfig/kernel file.
Thanks,
Andy |

The first obvious thing to check is the permissions on /dev/video, but
that is probably not the problem.
As well as having a module for the DVB aspects of the card, you also need
to load a tuner interface module as well.
One of the best sources of information to work through in order
to setup one of these type of cards is at
<http://www.gentoo-wiki.INFO/SAA7134>
Hopefully that will show you what tuner module and configuration
you need to setup.

If there is no tuner, then it is never going to receiver broadcasts ;+)
I think you are mistaken. The problem is that you have not loaded the
appropriate front end module to access the tuner -- something like /ttpci/
budget-core.ko and ttpci/budget-patch perhaps.
Also when loading modules with modprobe, it is usually a good thing
to append the -a flag so that other dependent modules are loaded as
well.
And also take a look at the site
<http://www.linuxtv.org/wiki/index.php/Main_Page>
for more technical information on all types of DVB cards and their setup
under GNU/Linux. |
