TV card in Linux

I finally get my asus TV card to work under Kubuntu 7.04.
The video worked but there wasn't any sound.
Googling I found following at:

You may try to use:
1) modprobe saa7134-alsa
2) sox -r 32000 -w -t ossdsp /dev/dsp1 -t ossdsp /dev/dsp
where /dev/dsp1 is your TV card sound device and /dev/dsp
your main soundcard.
Let sox run an open tvtime (or other TV application) from a
different terminal.

I didn't have sox installed so I run: sudo apt-get install sox
The bad thing you have to run
sox -r 32000 -w -t ossdsp /dev/dsp1 -t ossdsp /dev/dsp
every time to get sound.
