Video4linux2 bttv configuration parameters for K-World XPERT TV878 PCI TV Card
Eventually I fiddled around with the GPIO registers GPIO out enable and GPIO data enable, and I managed to get the audio to work.
The reference system is SuSE Linux 10.1 x86-64 with a Nvidia nForce3 250GB board with a Realtek AC97 Audio Codec. The kernel version is 126.96.36.199-4.
ALSA-driver-1.0.11 is used. The audio driver to load is snd-intel8x0 even though the chipset is nForce3 and audio codec is realtek alc650. snd-intel8x0 works for ICH6, ICH7 and Nvidia chipsets.
You need to place the following parameters in /etc/modprobe.d/tv. If your distro is not suse, place the paramaters in /etc/modprobe.conf for kernel 2.6 and above or /etc/modules.conf for kernel 2.4.

The key/important parameters to pass to the bttv module is gpiomask and audiomux.

Adding country support in common tv applications like kdetv and xawtv:
You need to find and edit Index.map and to create a country file with a list of frequencies in the respective application's directory.
The following code is specially adapted for Singapore tv channels.
[singapore] file = singapore.list
[Channel 5] freq = 175250 [Channel 8] freq = 196250 [Channel U] freq = 487250 [Channel News Asia] freq = 543250 [Suria] freq = 224250 [Kids Central] freq = 495250 [RTM 1] freq = 552500 [StarHub Test] freq = 743250
To add support for your own country, simply modify Index.map as needed and create a listing file for your country with a list of frequencies.
