SiS661FX Chipset Video Card and C-Media AC97 Issues...


Hi,

I recently bought a new motherboard with a lot of stuff bundled into it... here's a partial list:

Chipset:
North Bridge: SiS 661FX
South Bridge: SiS 963L

On-Board VGA: SiS 661FX Chipset (32MB RAM)

On-Board Sound: C-Media 9761 (AC97) codec

The above comes straight out of the manufacturer's manual.

I installed Redhat 9.0 (Shrike) and although the sound and videocard were detected, there are a few glitches...

1) The soundcard is detected as a SiS 7012 PCI Audio Accelerator. Detects fine, plays the test sound fine, but when I try to raise/lower the volume, it is either on full (no matter where the slider is on XMMS, xine, master volume control, etc.) or completely off. Looks like a mixer problem to me... By the way, fooling around with settings in any program does not help, same problem keeps cropping up.

2) The video card is detected as VESA (generic), and I get a garbled display when the GUI login screen starts up, but seems to work fine upon refresh. I can't simply select SiS661FX because Linux does not prode that particular driver by default. Also, the OpenGL mode runs very slow.

Any ideas on how I can fix the above? The websites for these companies are complete and utter sh*t, so don't bother with them....

Thanks.

A real video card and sound card would do the job nicely. Unless there has been a change, SiS doesn't offer very good Linux support. Onboard sound is located next to the CPU, therefore picking up the most noise and giving poor audio quality.


How about sound card configuring?
# Sound card config
Intel AC'97 and Creative Labs* onboard audio
Intel - Configuring Onboard Audio
ALSA download page, scroll down to Read-only anonymous CVS access is also available

I have a win<something> or some other kernel module driver I have to install.
# Compiling/installing kernel modules
You will need to have installed:
1. The developmental packages (compiler)
2. The kernel-source code that matches your running kernel
3. The module source or install code

Check out your system and look under the hood and see if you installed the stuff you need to do the job. Open an x terminal and type in this sequence of commands to see what kernel we are running and see if you have the kernel source installed:
Code:
[fancy@tinwhistle fancy]$ su -
Password:
[root@tinwhistle root]# uname -r
2.4.20-28.7
I am running kernel version 2.4.20-28.7. Do I have the proper source code?
Code:
[root@tinwhistle root]# cd /usr/src
[root@tinwhistle src]# ls -alc
total 3
drwxr-xr-x    4 root     root          136 Jun 12 14:53 .
drwxr-xr-x   16 root     root          424 Jun  4 12:04 ..
lrwxrwxrwx    1 root     root           14 Jun  4 12:11 linux-2.4 -> linux-2.4.20-28.7
drwxr-xr-x   16 root     root          584 Jun  4 12:11 linux-2.4.20-28.7
drwxr-xr-x    7 root     root          168 Jun  4 12:08 redhat
[root@tinwhistle src]#
I do have the same kernel version source code installed in the directory /usr/src/linux-2.4.20-28.7 and there is a symbolic link named linux-2.4 pointing to it.

If you don't see something similiar to this (but in color), you will need to install the kernel source.

NOTE: I noticed that Red Hat didn't make the symbolic link /usr/src/linux that all of the INSTALL files that I have read mentioned that I need. I may as well make one now to save editing the files in the source code every time I need to compile anything concerning the kernel. So, I'll make that link just now:
Code:
[root@tinwhistle src]# ln -s linux-2.4.20-28.7 linux         
[root@tinwhistle src]# ls -alc
total 3
drwxr-xr-x    4 root     root          160 Jun 12 15:46 .
drwxr-xr-x   16 root     root          424 Jun  4 12:04 ..
lrwxrwxrwx    1 root     root           14 Jun 12 15:46 linux -> linux-2.4.20-28.7
lrwxrwxrwx    1 root     root           14 Jun  4 12:11 linux-2.4 -> linux-2.4.20-28.7
drwxr-xr-x   16 root     root          584 Jun  4 12:11 linux-2.4.20-28.7
drwxr-xr-x    7 root     root          168 Jun  4 12:08 redhat
[root@tinwhistle src]#
Ah, there it is, so that's done.

Next, did I install the compiler?
Code:
[root@tinwhistle src]# gcc -v          
Reading specs from /usr/lib/gcc-lib/i386-redhat-linux/2.96/specs
gcc version 2.96 20000731 (Red Hat Linux 7.3 2.96-113)
[root@tinwhistle src]#
Yes, I have a compiler installed.

If you don't have those two things installed, you have to install them first off your install CD.

If they are installed, download the source and happy compiling. Make sure you carefully read the README and INSTALL files after extracting and before compiling/installing.
