Speaker noise from X

Hey all-

I posted this question a few days ago in the Slackware forum (oops...probably should have gone here) and got no replies so I thought I would wait a bit and post here. So here goes:

My video card GPU fan recently died so I had to replace it with a spare. Here is rundown of current software/hardware:

+ XFree86 4.3.0
+ 00:0d.0 VGA compatible controller: S3 Inc. ViRGE/DX or /GX (rev 01)
+ 00:0e.0 Multimedia audio controller: Creative Labs SB Audigy (rev 03)
+ Emu10k1 v0.20a driver from http://sourceforge.net/projects/emu10k1
+ Fluxbox 0.1.14
+ XF86Config-4

Code:

        Identifier  "Keyboard0"
        Driver      "keyboard"
EndSection

Section "InputDevice"
        Identifier  "Mouse0"
        Driver      "mouse"
        Option      "Protocol" "IMPS/2"
        Option      "Device" "/dev/input/mice"
        Option      "ZAxisMapping" "4 5"
        Option      "Emulate3Buttons" "no"
EndSection

Section "Monitor"
        #DisplaySize      300   230     # mm
        Identifier   "Monitor0"
        VendorName   "DEL"
        ModelName    "DELL D1028L"
        Option      "DPMS"
EndSection

Section "Device"
        Identifier  "Card0"
        Driver      "s3virge"
        VendorName  "S3 Inc."
        BoardName   "ViRGE/DX or /GX"
        BusID       "PCI:0:13:0"
EndSection

Section "Screen"
        Identifier "Screen0"
        Device     "Card0"
        Monitor    "Monitor0"
        DefaultDepth 16
        SubSection "Display"
                Depth     1
        Monitor    "Monitor0"
        DefaultDepth 16
        SubSection "Display"
                Depth     16
                Modes     "1024x768"
        EndSubSection
EndSection

O.K. now the problem:

Whenever the screen is required to redraw itself AND I am playing audio through XMMS I get a screaching beep/distortion out of my speakers. What I mean by the screen having to redraw:

- Scrolling down a web page
- Scrolling an ncurses screen such as a text file in Midnight Commander
- A hyperlink is coded to change colors, underline, etc on mouse over
- Xterm scolling output such as ls or cat

Since the old card was an NVIDIA I had to uninstall the old drivers to get OpenGL working again and all seems to be good there. Any ideas?

Thanks in advance,
-g00$e

Use ALSA drivers. They are much better than the OSS drivers and the OSS drivers that you are using could be the problem. If that doesn't work, try updating your Savage drivers. If it still gives you problems. Disable dmabus for the sound card.

All of the above are good suggestions, maybe try moving the card to another PCI slot, or moving the sound card to another PCI slot might help.
