I am beginning to think that I don't actually have an SBT something because I never actually saw those letters anywhere in my documentation. The chipset and manufacturer is right though.

Adding another card in saa7134-cards.c should work. If it does not, the module will either not compile or just will not work when loaded. The kernel will keep on working unless you mess around in the memory access code. If you are scared editing the file to a few lines of code, just change the unknown or the first card. Just adjust the values for composite and then S-VIDEO. Finally, find where the tuner is and find the audio clock.

First, backup the saa7134 directory that is under the kernel directory. Next backup .config in the kernel directory and no I did not mis-spell it. Third in /usr/src/linux-`uname -r` or your kernel directory make an .config that has only

CONFIG_VIDEO_SAA7134=m

In directory /usr/src/linux-`uname -r`/drivers/media/video/saa7134 run the commands below as root

modprobe -r saa7134 tuner videodev
make -C /usr/src/linux-`uname -r` M=$PWD clean
make -C /usr/src/linux-`uname -r` M=$PWD modules
make -C /usr/src/linux-`uname -r` M=$PWD modules_install
depmod
modprobe saa7134

If you are symlinked correctly, the path /usr/src/linux/drivers/media/video/saa7134/saa7134-cards.c should point to the file that I was talking about.

Thank you Electro for telling me how to recompile modules and load them without having to reboot.

After a month and a half break, I am going to work on this again. My problem is that even after I switched the two .vmux variables in the driver code, the card still has switched inputs. I am just a noob so I really don't know where to go from here.

2 years later -bump- same problem and same state, the main problem is that if i want audio, i need to fix this.

EDIT: Duplicating the working device and switching channel did not work (yes, i did edit all related file too and created a new "card" and defined the id)

Yeah, I had forgotten all about this and moved on. I no longer have that tuner.

Ok, the patch work. Now i have to figure out how to send the signal (jack 1/8 audio output from the card) to one of my HDA audio chipset line. How to i do that?
