Default nForce4 MIDI not working


I'm having trouble getting MIDI working on my new system (note: I primarily need raw midi to do sysex dumps). I've searched and searched and tried dozens of things but nothing seems to work. I'm hoping someone here might have some insight.

I'm running Fedora Core 4 (kernel 2.6.13-1.1532) on an Athlon 64 3500+ with Epox 9NPA+ Ultra mobo.

I tried using the default OSS drivers first (snd-intel8x0) and everything worked great except: no MIDI devices created. /dev/sndstat said "Midi devices: NOT ENABLED IN CONFIG". (I'm not sure what that means exactly; I haven't been able to find any config to enable it.)

After a quick look at the driver source code I began to suspect that MIDI support isn't implemented in snd-intel8x0. So I decided to try the nVidia drivers.

I installed NFORCE-Linux-x86-1.0-0306. Again, everything seems to be working okay, except: no MIDI devices.

lsmod gives me this:

## sound stuff
# nvidia stuff
alias snd-card-0 nvsound
alias snd-intel8x0 off
alias i810_audio off
install nvsound /sbin/modprobe --ignore-install nvsound ; sleep 1; /usr/bin/nvmix-reg -f /etc/nvmixrc -L >/dev/null 2>&1 || :
remove nvsound { /usr/bin/nvmix-reg -f /etc/nvmixrc -S >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove nvsound

# alsa stuff
#alias snd-card-0 snd-intel8x0
#options snd-card-0 index=0
#options snd-intel8x0 index=0
#remove snd-intel8x0 { /usr/sbin/alsactl store 0 >/dev/null 2>&1 || : ; }; /sbin/modprobe -r --ignore-remove snd-intel8x0
ARTS works fine using OSS but, of course, no ALSA.

I DO have audio support enabled in the BIOS, as well as MIDI (on int 10).

/proc/interrupts says:

 15:     427204          XT-PIC  ide1
NMI:          0
ERR:          0
I'm not sure what else to try. If anyone has any suggestions I'd really appreciate them.

BTW, notwithstanding MIDI, exactly what benefits do the nVidia drivers impart that the OSS drivers do not?? (Including the network drivers too: my NIC seems to work just fine with forcedeth.)

Thanks in advance!

Default Re: nForce4 MIDI not working

It is nvidia-installer.log
-> Kernel module compilation complete.
ERROR: Unable to load the kernel module 'nvidia.ko'. This is most likely
because the kernel module was built using the wrong kernel source files.
Please make sure you have installed the kernel source files for your
kernel; on Red Hat Linux systems, for example, be sure you have the
'kernel-source' rpm installed. If you know the correct kernel source
files are installed, you may specify the kernel source path with the
'--kernel-source-path' commandline option.

Default Re: nForce4 MIDI not working

I'm not clear which problem you're reporting here, as an nvidia-installer.log is for the graphics driver, and this thread relates to the NFORCE nvsound driver.

However, it looks like you're using some 3rd party patched 1.0-6629 graphics driver, which is no longer supported. If this problem reproduces with 1.0-8178 plus the patches from here:

please post your full installer log.
