TV Tuner card (saa7134) - good picture, no sound
 

Hello people

I run gentoo 2004.3 (2.6.9 kernel) on a P4 machine. I have this saa7134 based TV tuner card (Pinnacle PCTV Stereo).

I did a modprobe saa7134 and got the card working using tvtime. While I am getting the video of all the channels, there is no sound - just an ugly hissing noise.

dmesg gave me this output:

Please help me guys... I do not know what to do... Googling did not help me any.

Thanking you all in advance

Regards

Mee to facing the same problem
 

Hi
I too am from India.
I have Pinnacle pctv sterio and am facing the same problem but mine is Fedora Core 2 .
Any help ??

hi guys.. have you solved the problem? i don't have sound as well... could you post the answer here?

thankx

hi there,

i have an "old" pctv card working ok.
for sound just connect your line-out from the tv-card to line-in from the sound-card.

i never had sound in another way.

egag

i allready did that!

i have sound, but only noice

i can't tune any chanel....

oh, i thought it was just a sound issue.
wich program do you use for tv ?
and do you have no picture at all ?

egag

i'm using xawtv and tvtime... i just can't tune any program.. i only have noice (audio noice and video noice as well)

thankx a lot for your help

well...do you have that card "TV Tuner card (saa7134) ?
do you have the modules loaded ( look with "$lsmod " )
and v4l enabled ? ( there should be ' load "v4l" ' in your x-config file )

egag

eh, what do you mean with TV Tuner card?
i have actually the modules loaded.

lsmod shows all the modules, a few of them are from the tv card (saa7134)

i'm going to try adding ' load "v4l" ' in my xorg.conf file...

thankx so far

I have an video capture card (LifeView FlyVideo 3000FM) that uses one of the saa713x video grabber chips. I got it working and thought I would post something that will help people get sound working, but legolin beat me to it. To summarize what legolin is telling. If you use the command "xawtv & tvtime", it will load up xawtv and then load up tvtime without any problems. This will give you sound and as well fullscreen and deinterlaced video output. Muting can be a little tricky because it is not m like it usually is in tvtime. It is , to mute it. You will need to tell tvtime to use your sound card line volume to mute it. You may want to change capture in xawtv to none to decrease processor usage for xawtv.

It does help if you setup the video capture card that has the saa713x capture chip first and then setup other capture cards that uses a different capture chip.

With some video capture cards like the one I have, you have to include the tuner option when loading the saa7134 module. Also include the oss option for the saa7134 module if you want sound to work. Some peope with different PAL signals may need to change audio_carrier if they want sound to work correctly for their area.

The picture quality from saa713x chips is very excellent, but the programmer have to fix the automatic brightness, input selection (Composite, S-VIDEO, etc), and signal integrity detection.

Hi,

I could get sound to my Pinnacle PCTV Stereo card (driver saa7134) when I added "options tda9887 qss=0" to my /etc/modprobe.conf file as suggested in some other discussion thread, restarted my PC, and checked and unchecked Channel Management -> Use PAL-DK audio decoding in tvtime application.

I was having "audio carrier scan failed" lines in /var/log/messages and /var/log/dmesg. I have Fedora Core 3 with 2.6.9 kernel.

tv tuner card : no sound
 

Hi,

I had the same problem of having no sound with XawnTV or TVTime.
My distro is Ubuntu 7.04 Feisty Fawn and my tuner card uses a saa7134 chip.
The output of my tv tuner card is linked to the input (blue) of my (integrated) sound card.

I launched alsamixer in a terminal, and went to the right (use right arrow) to discover that there were 3 settings labeled "<Input so>". they were set to "mic", I just changed to "line" and now I have sound !

Hope this can help.

Cheers,

Ivantad

a sthg gentoo help:http://gentoo-wiki.com/HARDWARE_saa7134

If your video capture card does not have a line out jack, you will have to load up alsa-saa7134 module. Though the module name may change in future kernels, so double check the name.

If your video capture card does have a line out jack, make sure the sound card is correctly setup to receive audio from the Line In. Also make the loop cable is connected from the video capture card to the sound card's line in connector.

Some video capture cards based on saa7134 may need an AM IF chip for audio. One of the tdaXXXX modules might need to be loaded in order to hear sound.

To receive through the coax or tuner, you have to do a trial and error through the tuner list for the type of reception which can be either PAL, NTSC, SECAM. The list is located at "/usr/src/linux-`uname -r`/Documentation/video4linux/CARDLIST.tuner".

I recommend all sound and video tests to be done through either S-Video or Composite using a program such as tvtime. Then test the tuner after make sure the card works. Make sure the video card module (driver) can handle XVideo or else tvtime will not work.

BTW, Be careful loading both nvidiafb and nvidia modules. The nvidia module will get messed up if nvidiafb is loaded first.

Concerning the TDAXXX , as posted ub somehwree post:
I did make menuconfig and looked for :
/
9887
and nothing like this

I looked for all tda, they are all as "m" and kernel compiled and tried: no sound in tvtime. they all look like weird tda numbers but no 9887. Weird since it 's in the /usr/src... 2.6.22.5 & 2.6.22.6 somewhere. Can they be hidden ? (I am noob)
then once compiled:
lsmod | grep tda gives nothg
Thanks for helping !!
