Too many problems with a tv card (philips saa7134)

ffuentes · 2011-03-12 01:09:20

Hi, I have a tv card (with fm radio receptor). This Tv Card has no brand (selled by Dekermann) but after much work and search in the web can see video with this settings:

saa7134 card=42 tuner=43

saa7130/34: v4l2 driver version 0.2.16 loaded
saa7134 0000:03:06.0: PCI INT A -> Link[APC1] -> GSI 16 (level, low) -> IRQ 16

saa7134 0000:03:06.0: setting latency timer to 64

saa7130[0]: Huh, no eeprom present (err=-5)?

saa7130[0]: registered device video0 [v4l2]
saa7130[0]: registered device vbi0
saa7130[0]: registered device radio0

But I don't have sound and don't know how (after searching) to make the sound works. The only thing I know is the existence of a module called saa7134_alsa but I don't know how make it works.

arecord -l show this:

$ arecord -l
**** List of CAPTURE Hardware Devices ****
card 0: ICH [Intel ICH], device 0: Intel ICH [Intel ICH]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: ICH [Intel ICH], device 1: Intel ICH - MIC ADC [Intel ICH - MIC ADC]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

When I saw in /dev/ the existence of /dev/radio, I wanted to make work the radio with gnomeradio but this don't work and LIRC also didn't. And this program don't send any error message.

For LIRC I have loaded lirc_dev lirc_i2c modules, based in the LIRC web information. http://www.lirc.org/html/table.html#@hw-tv-card

Thank You

first, does the sound from normal audio card, work ? example, listen a mp3....

Gusar · 2011-03-12 12:30:02

What are you using to watch TV? Only mplayer supports direct audio, other apps (including tvtime) don't. Using sox with tvtime is the usual workaround. Not exactly pretty, but works.

Yes, it works well.

Tvtime and xawtv. I have tried to use sox. Linux only detect these audio devices:

$arecord -l
**** List of CAPTURE Hardware Devices ****
card 0: ICH [Intel ICH], device 0: Intel ICH [Intel ICH]
  Subdevices: 1/1
  Subdevice #0: subdevice #0
card 0: ICH [Intel ICH], device 1: Intel ICH - MIC ADC [Intel ICH - MIC ADC]
  Subdevices: 1/1
  Subdevice #0: subdevice #0

That is the audio from the mother board.

i've never had a tv card, so, my suggest is to search (google for example) in other wiki, such as ubuntu or fedora, or site like linuxtv.org

ffuentes · 2011-03-12 18:58:19

nTia89: That's what I have done.

swanson · 2011-03-12 20:20:31

Is the cards alsa module loaded? lsmod | grep XXX

I have this in my module options:
options cx88-alsa index=2
For my HVR1300 card. index=2 sets it to card no 2 for alsa.

You don't have saa7134_alsa loaded.

Yes, but I have enabled it with modprobe and a /dev/dsp1 or something similar does not appear.

Well, this line says it all:

/alsa: Sabrent SBT-TVFM (saa7130) doesn't support digital audio

Is this an internal card? Does it have audio-out? If yes, just connect that to line-in on your sound card. If there's no audio-out, then 'card=42 tuner=43' is not the correct option for this card.

ffuentes · 2011-03-12 22:38:50

Yes, is an internal card and does not have audio-out but I have not found a working configuration. (With this config. at least I see the video).

I'm using http://mstr.ueuo.com/saa/index.php?id=Y to search and try.

Army · 2011-03-13 11:11:25

I also have a tv card with this chip. Here's the script I use to watch analog tv with it

mplayer tv:// -af volnorm -vf yadif -delay 0.2 -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=1:immediatemode=0:channels=`cat ${HOME}/.bin/sender`

and my "sender" file looks like this

E7-ARD,E6-ZDF,E5-SWR_BW,SE10-BR,E10-Sat1,SE14-Pro7,E9-RTL,25-RegioTV,SE7-MTV,SE12-VIVA,SE6-Kabel1,SE9-Phoenix,SE11-SuperRTL,SE13-3sat,E12-DSF,SE15-EuroSport,E11-ZDF-Doku,SE16-RTL2,SE17-WDR,SE18-NDR,22-SF_DRS,47-SF2,24-ORF1,23-ORF2,26-N24,27-NTV,28-MDR,31-ARTE,34-DMAX,36-Das_Vierte,41-BR_alpha,42-HR,44-CNN,45-Bloomberg,50-AnixeSD,51-RBB

which of course you have to adjust yourself.

I also use this line in the modprobe.conf

options saa7134-alsa index=1

so the tv card always has the same index, which is important for the mplayer line to work.

DVB-T works out of the box.

@Gusar: You are correct!

Card box had a little cable, and all I needed to do was plug that in the card "audio out" and works well.

I thought you were talking to me about an internal plug (inside the machine).

Thank you.

Well, I only need to set lirc.

ffuentes · 2011-03-14 20:12:12

I can't make that lirc and my remote control can communicate.

dmesg | grep lirc

lirc_i2c: module is from the staging directory, the quality is unknown, you have been warned.

Following http://www.lirc.org/html/table.html#@hw-tv-card I have loaded lirc_dev and lirc_i2c modules but when I try to get signal of the remote with "sudo mode2 -d /dev/lircd" or "irw" not work with any house controller .

Padfoot · 2011-03-15 08:34:55

Unfortunately mode2 does not work with /dev/input devices and I suggest you use the /dev/input/by-id or by-path device node.

I too have a saa7134 device with a Phillips chipset (avermedia) and I find udev is very flakey regarding the /dev/lirc devices and the /dev/input/event device can change when other devices are added or removed. That's why I use the by-path or by-id nodes as they are static.

Firstly, make sure you have the device node added in /etc/lirc/hardware.conf

Of course, ensure you have lircd added to the modules in /etc/rc.conf so the daemon will start on boot thus negating the next step

And ensure the lirc daemon is running with /etc/rc.d/lircd restart

Now run irrecord -n -d <device node> -H devinput /etc/lirc/lircrd.conf (make sure you back up the original lircrd.conf first)

All going well, you should now be able to record your remote's buttons.

Cheers.

I don't know why, but I can't see my infrared point in /dev/input

Modules are loaded, daemon is started, remote controller cable is connected, tv card is working.

$ ls /dev/input/by-path

What's the output of

??

$ ls /dev/input/by-id

Padfoot · 2011-03-17 05:37:37

Ok, From the output of ls /dev/input/by-path and ls /dev/input/by-id along with your dmesg and cat /proc/bus/input/devices output posted earlier, no device has been registered for your IR remote. This leads me to think you do not have the correct card/tuner insmod options.

If the remote was being picked up, dmesg | grep saa (similar to the output in your 1st post) would have the IR device being registered on a /dev/input/eventX node near the top of the output.

Let me have a look at http://linuxtv.org to see if I can find beter insmod options for your TV card.

Cheers.

[UPDATE]

Ok, looking at the vendor website you provided in your 1st post, the only TV card I could find on there is the TARJETA DE TV SIN FM. This card is also reported to be a KWorld Studio TV Terminator.

Looking on linuxtv.org, your insmod options should be card=65 tuner=54.

Try those options and report back the output of:

dmesg | grep saa
cat /prop/bus/input/devices
ls /dev/input/by-id
ls /dev/input/by-path

Cheers.

Thank you, I have tried this and settings works but the video goes out via Composite and I can't tune TV in tvtime, but in XAWTV i can do it.

LIRC is detected by dmesg but not signal is showed either mode2 or irw commands.

I surrender.

At least I can see television.

Padfoot · 2011-03-18 06:43:30

Not a problem.

If you have TV in Xawtv but not TVtime, you most likely need to copy across your channels.conf file.

dmesg reporting LIRC being loaded only means the LIRC daemon is running. Your remote device still needs to be configured.

If you like, I can help you do that (by posting the output of the commands in my previous post).

Of course I understand these things can be quite frustrating. You should have seen the issues I had when first using my TV card on Linux. Support for it wasn't built into the kernel at that time, so there was a lot of modules to be patched just to get basic functionality. For a beginner with Linux, believe me there were a lot of things being thrown around the room!

But I pressed on, and finally, with a lot of help from linuxtv.org, I got it going.

So let me know if you want to continue. Demoralising as it may be at the time, the satisfying feeling of triumph once you have it working really goes a long way to tackling more difficult issues in the future.

Cheers.

ffuentes · 2011-03-18 22:12:36

You are right, thank you for your help and kindness.

I would want to know is if the remote receptor actually works. Is a cable connected to the card with a little plastic receptor of signals which I don't have see works ever. I don't have Windows installed here.

Another thing is radio FM, that I don't know how to set and information in forums are not much. Your suggested card and tuner data are from a card without FM function, at least for the spanish title: TARJETA DE TV SIN FM.

It's all. xD

Thank you again.
