I'm running a Dell Latitude D610 and I have all sound support except MIDI. Of course, I didn't notice until I tried to utilize KGuitar for tablature. Here's the hardware: Intel 82801...

$ lspci | grep -i audio
00:1e.2 Multimedia audio controller: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) AC'97 Audio Controller (rev 03)
$ lsmod | grep -i snd

snd_intel8x0m 14092 1

ac97_bus 3072 1 snd_ac97_codec

snd 41316 11 snd_intel8x0,snd_intel8x0m,snd_ac97_codec,snd_pcm_ oss,snd_mixer_oss,snd_pcm,snd_timer
soundcore 6880 1 snd
snd_page_alloc 8328 3 snd_intel8x0,snd_intel8x0m,snd_pcm

In the KInfoCenter, it states "MIDI devices: NOT ENABLED IN CONFIG"
The KDE Control Module does not have a MIDI device listed nor a mapper.

Any idea what's missing?
