[mythtv-users] No Sound with nForce chipset

    First off, knoppmyth totally rocks. I wasted a good week trying to
    get Myth to work on SuSE 9.0, then I switched to this. Thanks for the
    good work! 

    However, I still have NO sound. I've been searching and have found
    references on some sticky thread on my problem, but I cannot find it.
    Here's the lowdown: 

    It's a MSI MEGA 180 box that has the nForce chipset. 
    Athalon 2500+ (barton) 
    512 M ram 
    PVR 350 

    Now, I've got everything working, except sound. There is no sound
    out from either the SPDIF, the analog out on the sound card nor the

    so looking in /etc/modules.conf it says: 

    alias snd-card-0 snd-intel8x0 

    which is wrong, so naturally I did an "lsmod" and as expected: 

    ---< snip >--- 
    snd-mixer-oss 11640 0 [snd-pcm-oss] 
    snd-intel8x0 17636 0 
    snd-pcm 56000 0 [snd-pcm-oss snd-intel8x0] 
    snd-timer 14088 0 [snd-pcm] 
    snd-ac97-codec 32832 0 [snd-intel8x0] 
    snd-page-alloc 4316 0 [snd-intel8x0 snd-pcm] 
    snd-mpu401-uart 3168 0 [snd-intel8x0] 
    snd-rawmidi 13088 0 [snd-mpu401-uart] 
    snd-seq-device 3824 0 [snd-rawmidi] 
    snd 27940 0 [snd-pcm-oss snd-mixer-oss snd-intel8x0 snd-pcm
    snd-timer snd-ac97-codec snd-mpu401-uart snd-rawmidi snd-seq-device] 
    soundcore 3524 3 [snd] 
    ---< snip >--- 

    so, I'm thinking I need to compile the nForce linux platform
    drivers. So, I obtained the latest tar.gz and when I type "Make",
    the compile fails with the following (parsed for clarity) messages: 

    /usr/include/asm/mpspec.h:6:25: mach_mpspec.h: No such file or

    /usr/include/asm/mpspec.h:8: error: `MAX_MP_BUSSES' undeclared here
    (not in a function) 

    /usr/include/asm/smp.h:73:26: mach_apicdef.h: No such file or

    In file included from nvhw.c:16: 
    nvhw.h:29:27: linux/wrapper.h: No such file or directory 

    /usr/include/asm/irq.h:16:25: irq_vectors.h: No such file or

    And a few others. My question is, where did I go wrong, and how does
    one get the nForce audio to work on knoppmyth?
