Philips SAA7130 based tv tuner card sound problem?
 
I have installed a Philips SAA7130 based TV tuner card on my computer which works fine in WindowsMe. I tried to configure it using SAA7134 module on Mandrake Linux (with 2.4.22-16mdk kernel). At present I am able to get the picture clearly using xawtv application. However the audio quality is very poor.
I use the following method:
At the root prompt, I type
modprobe saa7134 card=4
and then
xawtv&
How would I be able to get the sound clearly.

I also tried to configure the card on Red Hat Linux (kernel 2.4). Since driver for saa7134 is not available with kernel 2.4, I downloaded the saa7134 driver from the site and tried to create a module. However I got the error when I performed "make modules". Please give the details of configuring a module from .gz files.

Thanking you
Sushant

modprobe saa7134 card=4
just use the command

modprobe saa7134

Along with this, you will need to load the bttv and tuner modules for you to view TV properly
The commands will be as follows

1. for bttv

modprobe bttv card=x radio=y pll=2

Note:

x - will be a value between 1 to 80 ( see bttv documentation in
/usr/src/linux-*/v4linux/bttv/ )

you can try and experiment bttv card= values from 1 to 80 and find out which value works with your card.

y - will be either 1 for enabling, or 0 for disabling radio.

2. for tuner

modprobe tuner type=5 audiomux=2 debug=1

type=5 is basically the phillips PAL tuner applicable for India

----
FYI, these are the values that I use

modprobe bttv card=63 radio=1 pll=2
modprobe tuner type=5 audiomux=2 debug=1

Once when you get your TV tuner working, you can put all these commands in a shell script, make it executable and put in a directory say (/usr/local/load_tv.sh)

Now, in the file /etc/rc.local, call this script at the end

/usr/local/load_tv.sh

Hope that helps..

Thanks for your suggestion. However when I tried the procedure as mentioned by you, I was not able to load the bttv module by using modprobe bttv ...... It gave me a message module not found. But when I gave the command dmesg, in that it showed bttv module loaded. I could not get the proper sound from the card. What is the next solution.
