HELP ! Can't get SC400 souncard to work in Linux

Neděle Listopad 14 21:33:25 CET 1999

It has been a while since I got mine working, but here are a few of my
thoughts:

1.  I am on a RedHat 5.0 system

2.  I had to recompile the kernel, and I compiled the sound driver as a
module.

3.  You may want to find out what your "SC400" really is.  Go to Aztech's
website and see how you can look up the serial number on the card to figure
out which of Aztech's models it really is.  Mine was a Sound Galaxy NX Pro,
I think, and other SC400 revisions are different cards.

4.  I recall that all I compiled into the kernel was Microsoft Sound System
drivers and generic OPL stuff the same as you.

5.  Here is the sound section of  /usr/src/linux-2.0.32/.config
    #
    # Code maturity level options
    #
    CONFIG_EXPERIMENTAL=y
        <lines deleted>
    #
    # Sound
    #
    CONFIG_SOUND=m
    # CONFIG_PAS is not set
    # CONFIG_SB is not set
    CONFIG_ADLIB=y
    # CONFIG_GUS is not set
    CONFIG_MPU401=y
    # CONFIG_UART6850 is not set
    # CONFIG_PSS is not set
    # CONFIG_GUS16 is not set
    # CONFIG_GUSMAX is not set
    CONFIG_MSS=y
    # CONFIG_SSCAPE is not set
    # CONFIG_TRIX is not set
    # CONFIG_MAD16 is not set
    # CONFIG_CS4232 is not set
    # CONFIG_MAUI is not set
    CONFIG_AUDIO=y
    CONFIG_MIDI=y
    CONFIG_YM3812=y
    MPU_BASE=330
    MPU_IRQ=9
    MSS_BASE=530
    MSS_IRQ=10
    MSS_DMA=3
    DSP_BUFFSIZE=65536
# CONFIG_LOWLEVEL_SOUND is not set

6.  Here is the output of cat /dev/sndstat:

    $ cat /dev/sndstat
    Kernel: Linux betty 2.0.37 #11 Tue Aug 24 06:46:51 PDT 1999 i486
    Config options: 0

    Installed drivers: 
    Type 10: MS Sound System
    Type 24: MS Sound System (AXP)
    Type 27: Compaq Deskpro XL
    Type 1: OPL-2/OPL-3 FM
    Type 5: Roland MPU-401

    Card config: 
    MS Sound System at 0x530 irq 10 drq 3
    Roland MPU-401 at 0x330 irq 9 drq 0
    OPL-2/OPL-3 FM at 0x388 drq 0

    Audio devices:
    0: MSS audio codec (CS4231)

    Synth devices:
    0: Yamaha OPL-3

    Midi devices:
    0: MPU-401 0.0  Midi interface #1

    Timers:
    0: System clock
    1: MSS audio codec (CS4231)

    Mixers:
    0: MSS audio codec (CS4231)

7.  (CDROM) One change I did make was in
    /usr/src/linux-2.0.32/include/linux/sbpcd.h
  #define CDROM_PORT 0x630
  Because it was too slow otherwise waiting for it to auto detect.

8. I was never able to get sound input (i.e. microphome) to work reliably
under Windows, and I have not tried to test whether this setup described
above will work for input.

Hope this helps and was worth the wait,
