View Full Version : saa7134 & FC5 video but no audio

13th May 2006, 06:41 AM
I'll try to keep this short & sweet because nobody likes reading long posts. I have a kworld tv-terminator card and I've had luck getting the video to work under gentoo and now FC5 but I've never been able to get the audio to work correctly. Most recently, I've looked at the following page (http://www.linuxtv.org/v4lwiki/index.php/Saa7134-alsa) which recommend adding "oss=1" to the end of the modprobe command. Unfortunately I'm getting errors whenever I try to watch tv under mplayer using the command
mplayer tv://"insert channel" -tv driver=v4l2:device=/dev/video0:chanlist=us-bcast:alsa:\

Ok, so it was longer than I hoped :p

I've got a Kworld KW-LTV7131RF card and I'm trying to get it working too. I found the following information at

The KWorld Studio TV Terminator is based on the SAA7131E Chipset. and should be well supported in Linux Distributions containing kernel versions 2.6.14 and up. TV-Tuner, Radio, Sound and remote control features are supported under v4l. The card does not have an eeprom so it is necessary to pass card=65 and possibly tuner=54 as options to the saa7134 kernel module. Automatic tuner detection works starting with distributions using kernel version 2.6.15. On the application sde, TV-Time, KdeTv and KRadio work well with this card. These cards provide audio via the PCI bus and no externel audio loop-back cable is required. Build v4l from sources: V4L Wiki http://www.linuxtv.org/v4lwiki/index.php/How_to_build_from_mercurial

I've only been a Linux user for 5 days, so I'm still learning how to apply this information. For example, I don't know how to pass options to a kernel module. Is that as simple as typing "# saa7134 card=65"?

To pass the options to a kernel module, see:
