Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I have a BT878 based TV/video capture card, an older style WinTV card. On the back of the card there is a line-out that I have plugged into the line-in of the sound card. I would like to be able to activate the line-out of the capture card so I can receive sound from it even when not using something like 'tvtime'. My reason for doing this is that I would like to use VIC and RAT (two separate programs for multicast tranmission of video and audio) to transmit the TV program. When 'tvtime' is not running, the line is mute but I am able to grab video with VIC at a full 30fps. When I run tvtime, my frame rate drops down to 15fps but the sound is at least enabled so RAT gets a signal. I really want to have full frame rate and sound for the reason I'm doing this.
My question is then, how do I enable the sound without having to run a program like tvtime? Is there an option to a module I can set? I've looked over /proc and I haven't found anything.
I am using Debian Sarge with kernel 18.104.22.168. Most drivers (including bttv etc.) are compiled as modules.
I have an ati bt based tv card as well, and I found if you leave the line volume turned up you will get sound. You may have to try different options for your sound card. I have an audigy 2zs and I have to have the analog mix turned up too. You may want to check here too, /linux-22.214.171.124/Documentation/video4linux/bttv. I didn't know to load the i2c module till I read some of that. There is also a line in the tvtime config file in /usr/local/etc/tvtime that you can change the mute on exit option to off so it doesnt mute the sound when you exit tvtime.
