If the configuration utility of your distribution doesn't support
ALSA, you have to create the entries in modules.conf manually.
I have two other devices around as well:
1. USB Roland MIDI. This appears to have been configured
The hotplug scripts load the driver even when it isn't configured. And
because of this, it might be loaded before the other drivers; so there
should be an entry for this in modules.conf.
so I need some quick way of testing it out. Maybe
I'll just start
up rosegarden and see if it receives anything.
To see any received data, run "amidi -l" to see a list of ports, then
run "amidi -d -p hw:X". (You need a recent ALSA version for amidi.)
To play a .mid file, run "pmidi -l" to see a list of ports, then run
"pmidi -p X:0 something.mid".
2. SW60XG ISA sound card. This uses no IRQ or DMA,
just a settable port
address. The card is supposed to be accessible using an mpu401 driver.
The configuration for your three cards should look like this:
alias char-major-14 soundcore
alias char-major-116 snd
options snd cards_limit=3
alias snd-card-0 snd-xxxxxx
alias snd-card-1 snd-usb-audio
alias snd-card-2 snd-mpu401
options snd-card-0 index=0
options snd-usb-audio index=1
options snd-mpu401 index=2 port=0x330 irq=-1
# OSS emulation
alias snd-slot-0 snd-card-0
alias snd-slot-1 snd-card-1
alias snd-slot-2 snd-card-2
alias sound-service-0-1 snd-seq-oss
alias sound-service-0-8 snd-seq-oss
alias sound-service-0-0 snd-mixer-oss
alias sound-service-0-3 snd-pcm-oss
alias sound-service-0-12 snd-pcm-oss
alias sound-service-1-0 snd-mixer-oss
alias sound-service-1-3 snd-pcm-oss
alias sound-service-1-12 snd-pcm-oss
alias sound-service-2-0 snd-mixer-oss
alias sound-service-2-3 snd-pcm-oss
alias sound-service-2-12 snd-pcm-oss
The driver name for your first sound card depends on what card you
actually have, see <www.alsa-project.org/alsa-doc/>. The port address
for the snd-mpu401 driver must be set to the same value as selected on
the card.
