    Subjectproblems with Audiotrix Pro driver
    Ok, here is what I found to date.

    I am using Michael Chastain's sound-module.2197 patch, which improves
    the Makefile and some other things, but I checked those things in the
    bare linux-2.1.97.tar.bz2 archive.

    I started with modular sound, but as I had some problems, I've gone to
    static drivers for the moment, so that I can prove everything works at
    least in this way. Here is the relevant part of .config:

    # Sound
    # CONFIG_SOUND_PAS is not set
    # CONFIG_SOUND_SB is not set
    # CONFIG_SOUND_ADLIB is not set
    # CONFIG_SOUND_GUS is not set
    # CONFIG_SOUND_MPU401 is not set
    # CONFIG_SOUND_PSS is not set
    # CONFIG_SOUND_MSS is not set
    # CONFIG_SOUND_SSCAPE is not set
    # CONFIG_SOUND_MAD16 is not set
    # CONFIG_MAD16_OLDCARD is not set
    # CONFIG_SOUND_CS4232 is not set
    # CONFIG_SOUND_MAUI is not set
    # CONFIG_SOUND_OPL3SA1 is not set
    # CONFIG_SOUND_SOFTOSS is not set
    # CONFIG_SOUND_VMIDI is not set
    # CONFIG_SOUND_UART6850 is not set

    # Additional low level sound drivers
    # CONFIG_LOWLEVEL_SOUND is not set

    And the output of /dev/sndstat:

    First, compilation problems. hex2hex.c has a bad char at line 84, as I
    mentioned in another message. In the Makefile, hex2hex couldn't be run
    because 'make' didn't find it. Changing 'hex2hex' to './hex2hex' did it,
    at line 304 of the original Makefile and at line 234 of the sound-module
    patched Makefile. And even after that, the trix_boot.h file produced a
    lot of warnings and prevented compilation of the trix.c file, which was
    fixed by changing this:

    static unsigned char trix_boot[] __initdata = {

    to this:

    static unsigned char trix_boot[] = {

    in the generated trix_boot.h. I was about to change hex2hex.c, but I'm
    not sure enough of what this "__initdata" thing is supposed to do, so I
    just "fixed" trix_boot.h (maybe I *broke* it even further though). For
    those who want to do their own testing, the trxpro.hex file can be found
    on .

    Compilation of soundcard.c gave me two warnings, one at line 288 stating
    that "'proc_root_sound' defined but not used" and the other at line 811
    stating that "'sound' defined but not used".

    One thing that I was wondering is how to avoid using an IRQ with the
    Audiotrix MPU emulation? In the DOS setup program, the defaults for IO
    and IRQ are 0x0330 and None. I left the default 9 in my Linux

    CONFIG_SOUND_YM3812 seems to be needed for MIDI to work, is that normal?
    If it is, why isn't it included automatically like SB is (this is
    related to the new Makefile)?

    Finally, the mixer doesn't work properly.

    [pp@theta pp]$ aumix -q
    Synth 21, 21, P
    Pcm 50, 50
    Line 32, 32, P
    Mic 16, 16, R
    CD 0, 0
    Mix 0, 0, P
    Pcm2 21, 21
    IGain 7, 7

    As you can see, there is no volume (it is greyed out in the ncurses
    interface) and changing the Line volume affects the volume of the CD
    input (this used to work correctly).

    Now, I'm recompiling everything as modules to check this out... Stay
