SAA7133/SAA7135 Tv Tuner Help

apocolpse · 12-26-2006, 08:35 PM

Hey guys,

I'm running Fedora core 6, and recently installed a KWorld Tv tuner that uses the Philips Semiconductors SAA7133/SAA7135 chipset. I installed tvtime via yum from the livna repo, and I get not picture or audio. I tried searching online and this one guy did a

" modprobe saa7134 card=81 tuner=54"

on the command line, but that didn't work.

"/sbin/lspci -vv" returns:

Code:

A part of dmesg returns

I'm running on 2.6.18-1.2868 Kernel and a Nvidia Geforce FX 5200. Does anyone know what I could do to get this to work ??

The reason why "modprobe saa7134 card=81 tuner=54" does not work is because you have to unload the module first. Unloading and loading the module with the above options every time your computer boots up in Linux gets annoying. To fix this, in /etc/modules.conf or /etc/modprobe.conf include the following lines.

Code:

alias char-major-81-0 saa7134
options saa7134 card=81 tuner=54

Unload the module by doing modprobe -r saa7134 or rmmod saa7134 and the load module by doing modprobe -v saa7134. You should see it is using the optons you added in the modules.conf or modprobe.conf.

In tvtime first test the S-Video or Composite (RCA) to find out if it works. If it works, hopefully the tuner will work. If it does not, you will have to try each tuner in the tuner list.

BTW, I prefer looking at the whole entire logs from the start of booting. Summarizing the logs is ok but usually the most important errors are left out.

I also purchased a KWorld card, the DVB-T 220 with the same specs as listed.

lspci -v

Multimedia controller: Philips Semiconductors SAA7133/SAA7135 Video Broadcast Decoder (rev d0)

I checked my log and it had the following on boot

Now tvtime has always worked for the video, just I had no sound. I loaded the 7134-alsa module, "modprobe saa7134-alsa" and ran the command given on the http://www.linuxtv.org/v4lwiki/index...TV100)_CardBus page

sox -c 2 -s -w -r 32000 -t ossdsp /dev/dsp2 -t ossdsp -w -r 32000 /dev/dsp &

to redirect the sound and I now have sound.

My next challenge is to have the sound start automatically and I would prefer not have to use the script mentioned in the page.

I hope this helps someone.

Probably tvtime needs to be patched to playback audio. Try using mplayer with the audiofile option. It will not give you the same quality as tvtime, but it should work.

It is best to use a PCI card that has a Line out jack to loop it to the sound card. For notebooks it is best to use a DV device that uses IEEE-1394a/b (aka Firewire or i.Link) to capture video and audio. Then use mplayer to play it back. The device I suggest that does this is Canopus ADVC110.
