Will do

It just sat there

OK

few seconds, do 'cat /proc/interrupts', and look at the CPU column for
EMU10K1. If that number increases, the hardware is working fine.

OK, you mean run cat /dev etc in one shell, and cat /proc .. in another.
Yes, did that, and the CPU column increased.

/proc/driver/ only has one thing in it. It's white, it's called rtc, and
it's got todays date on it. Anyone can read it, nothing else. 1 byte.

say the same.

Well, I'm not sure I've found a mixer yet. I tried to adjust the volume
and it says unable to open audio device /dev/mixer check you have
permissions and sound support in your kernel.

root has rw access but that's all for mixer and mixer1

>> ls -l /dev/dsp went like this:
>> crw-------    1 root     root      14,   3 Jan 30  2003 /dev/dsp

device, major number 14 means OSS (Open Sound System), and minor 3 means
Digital audio. So this is fine too.

Cool :-)

>> id (as me) went like this:
>> uid=500(john) gid=500(john) groups=500(john)
>> While that might look like a permissions thing, I'm running now as root
and getting nothing.

> Can you run through the above one more time, just to make sure we
haven't missed anything?

I think that's what I've done, let me know if I missed anything. The id
was the same.

> Also, emu10k1 based cards usually let you route audio out of different
plugs. So you can put audio out of all you sockets, even the mic one
etc. Check you don't have audio coming out somewhere unexpected :)

Nothing. I haven't the wherewithall to check the digital outs tho. I
checked with headphones.

Thanks for your help so far :-)
