No video and sound with tv card saa7134

Redostrike · 2010-02-15 19:13:12

I cant seem to get my tv card working as i dont understand alot of stuff about linux at the moment.

I got alot of info on types of my card but as i said i really cant get it to work.

Here is the info i got:

hardware: Compro Technology, Inc. Compro VideoMate Gold+ Pal
software: tvtime

Dmesg:

saa7134[0]: subsystem: 185b:c200, board: Compro VideoMate Gold+ Pal [card=49,autodetected]
input: saa7134 IR (Compro VideoMate Go as /devices/pci0000:00/0000:00:06.0/0000:01:07.0/input/input4
saa7134[0]: subsystem: 185b:c200, board: Compro VideoMate TV PVR/FM [card=40,insmod option]
input: saa7134 IR (Compro VideoMate TV as /devices/pci0000:00/0000:00:06.0/0000:01:07.0/input/input11

Surfing the web i found some things:

http://www.wlug.org.nz/TvTunerCards
http://www.mythtv.org/wiki/Compro_Video … _Gold_Plus

I have tried these things:

rmmod saa7134
(there was a message somthing about saa7134_alsa)
rmmod saa7134_alsa
(removed fine)
modprobe saa7134 card=40 tuner=41 alsa=1

Fired up tvtime nothing!!

Any help for this noob please

Hi,

AFAIK, there is a lot of possible combinations of the "card" and "tuner" values, but i was lucky that the code given in this page (in spanish):

http://sipakal.blogspot.com/2007/08/tun … buntu.html

modprobe saa7134 card=21 tuner=38 gbuffers=4

was exactly the one required to make work my tuner card, but maybe this doesn't work for you, 'cause my card isn't the same than yours:

[renuvio@myown modprobe.d]$ dmesg | grep saa7134
saa7134 0000:00:09.0: PCI INT A -> Link[LNKA] -> GSI 5 (level, low) -> IRQ 5

I hope this may be useful for you. Good luck.

I have a tv card with this chip as well and with tvtime I didn't have a chance to successfully run tv

But it works with mplayer! I use the following script

#!/bin/bash
mplayer tv:// -tv driver=v4l2:norm=PAL:fps=25:width=768:height=576:device=/dev/video0:chanlist=europe-west:alsa=yes:adevice=plughw.1,0:audiorate=32000:forceaudio:immediatemode=0:channels=\

E5-SWR_BW,\

-af volnorm -vf pp=lb -vo xv -delay 0.2

Of course you'll have to adjust some values, but this way it might work for you as well.

audiorate=32000:forceaudio:immediatemode=0

These options are VERY important, otherwise you won't get any sound!

I got image to work using these settings:

modprobe card=49 tuner=5 alsa=1

No sound yet any thoughts?

with these cards you usually need a patch cable running from your card's output to your soundcard's line in input

But it's very possible the card has no audio-out, so no way to use a patch cable. You need an app that can handle internal audio. MPlayer does, Army gave the necessary options. For tvtime, a new version is in development that can handle audio, but until that's released you need to route the audio using an external app, with sox for example:

sox -q -r32000 -c2 -t ossdsp /dev/dsp1 -t alsa default

assuming /dev/dsp1 is the tuner.

I think eldragon hit it on the nail. I have a card that uses the same module and I had to run a cable from the tv card to the line-in on my sound card. This not needed for digital tv, however.

alsamixer -c 1 would bring up the settings for the tv tuner

renuvio · 2010-02-16 01:05:17

That's right, my tv tuner require too that cable from sound output to the soundcard line input.

If the OP's card is similar that's enough; the last thing i need it was to unmute and raise the volume of line input in alsamixer (50% is just fine in my box).

Redostrike · 2010-02-16 16:51:36

ok i'm using the patch cable i have sound but 2 things happen now:

Constant sound of my tv when my x is running.
When i start tvtime i have no sound anymore. Only if if i change the station then i have sound like 2 sec. And then its gone.

And i have i think mono sound as the right side of my boxes are very queit. (i'm not familiar with sound stuff).

The sox command did not work (i have sox installed).

EDIT: If i mute the tvtime then i can hear sound constantly (temporary fix)

You'll have to mute the line in when you aren't watching tv.

There are volume controls in myth, see if they are messing with your main mixer.
