[PlanetCCRMA] The Oxygen 8 works! ... but...

[Mark Knecht]

Joseph,
   I'm sorry, but I just wasn't paying close enough attention to the earlier
part of the thread. You will not get jack to run until alsa is loaded. If
alsa fails, there's nothing for jack to talk to.

   The key problem here is this part:

Starting sound driver snd-cs4236 \
/lib/modules/2.4.19-1.ll/kernel/drivers/sound/isa/cs423x/snd-cs4236.o:
Hint: insmod errors can be caused by incorrect module parameters,
including invalid IO or IRQ parameters.
      You may find more information in syslog or the output from dmesg
init_module: No such device

   It looks like you have two audio devices installed. For testing purposes,
do you need the usb stuff? Can you:

1) Disconnect the Oxygen 8
2) Clean your modules.conf file out except for like the first 3 lines. (SAVE
A COPY OF WHAT YOU HAVE NOW!!!!)
3) Rerun alsaconf
4) Starting with this clean modules.conf file see if you can get alsa
loaded?

   I am suspicious of the lines:

# snd_irq=5 snd_mpu_irq=9 snd_dma1=1  # snd_dma2=-1 snd_isapnp=0
options snd-card-cs4236 port=0x530 cport=0x120 irq=5 dma2=1 dma1=0 \
id=CARD_1 index=1

To me this looks like you are specifying the specific IRQ to be used. I'm
not at all sure that's a good idea, especially insmod is saying:

Hint: insmod errors can be caused by incorrect module parameters,
including invalid IO or IRQ parameters.

Possibly it's the right thing to do, and possibly there is a conflict. I'm
not sure. 'cat /proc/interrupts' might tell you something.

   I have not faced a problem quite like yours, so take these suggestions
with a grain of salt.

Mark

OK, I've put in the fixes that Fernando suggested to my
/etc/modules.conf
Restarting ALSA, I got:

[root at gimel midisport-firmware]# /etc/rc.d/init.d/alsasound start

I then started jackd with the arguments that its docs suggested, and got
the following:
