can't get sound on tvcard

[Emon]

Hi again guys

An old problem has resurfaced

I can't get sound on my tvcard after changing hardware!!

My current Motherboard is GA-MA785GPM-UD2H from Gigabyte.
My Processor is AMD Athlon II X2 250.
My OS is openSUSE 11.3_x86_64.
I am using the built in sound card as well as the graphics.

The program I use to watch Tv is tvtime.
Both the programs (sox & tvtime) are from packman repositories. In fact I have switched my system packages to packman repository.

The 'sox' script the I used for so long, looks like this
...........
#!/bin/bash
#This script is for automatically loading 'sox' with specific parameters.
#modprobe saa7134-alsa index=1,2
sox -q -c 2 -s -r 32000 -t ossdsp /dev/dsp2 -t ossdsp -r 32000 /dev/dsp
............

I know that line 3 is commented, but still it used to work; & I have tried uncommenting it but to avail.
It used to work like a charm but now ever time I try to execute the script, it says
.....................
emon@magic-box:~> /home/emon/sox_script_for_tv.sh
sox FAIL formats: can't open output file `/dev/dsp': Device or resource busy
....................

I hope I haven't broken any posting etiquette by reviving a thread this old.

anyway I would be really grateful if some one can decipher all this for me.

Thanks

I have been fiddling around a bit more and I observed the following things

Under Yast->Sound it shows two sound cards

0 - SBx00 Azalia (Intel HDA)
1 - ATI Technologies Inc

Why is that ?? I only have one card

But this is the most interesting thing that I observed;

Say, I login & start Amarok, then if I try to execute the sox script for tv then it shows
.....................
emon@magic-box:~> /home/emon/sox_script_for_tv.sh
sox FAIL formats: can't open output file `/dev/dsp': Device or resource busy
....................

and fails to produce any sound for tvtime.
So if I close amarok or stop the music & then execute the script, I get sound on tvtime.

But if I open tvtime first, execute the script to get sound, and then try to start amarok, KDE simply notifies that:

..................
The audio playback device HDA ATI SB (alc889a) does not work.
.................

and fails to play any music.
I have to stop the script from executing & restart Amarok.

So with my little knowledge, it seems to me that the applications are not able to share the hardware resource!!

Any correction , pointers/tips will be highly appreciated

You might want to read this for sound problems

Multi-media and Restricted Format Installation Guide

Your motherboard probably has a sound card so that is where the second one comes from.

Hi gogalthorp

Thanks for the link; but you see, I have already switched system packages to Packman... so Restricted Format should not be a problem

Your are right, my mother board has a sound card & that's the only sound card in this machine.... so why two devices are being shown??

Thanks

[mikesd]

is the tuner card an ATI chipset by any chance?

[Emon]

No...
It's Avermedia AvertTV Super 007.
The chipset is SAA7131/SAA7133/SAA7135 according to Yast

One of the most popular applications for video capture cards is to capture video and audio for live Internet video streaming. The live stream can also be simultaneously archived and formatted for video on demand. The capture cards used for this purpose are typically purchased, installed, and configured in host PC systems by hobbyists or systems integrators.
