ok, I didn't know about that setting in Ardour, I'll check it.

do you set up envy before or after starting Ardour?

I don't have any SPDIF devices

I did try various settings last night after recording the violin parts 
without monitors.  I just didn't get any sound when the digital mix was

I'm using 48000.  The artist wanted 96000, but my computers gets xruns at 
4800, and will stop recording at 96000 with 'jack thought ardour was too 
slow' type messages.   I did some 'export to CD' with dithering and it 
sounds just fine to me (-:

what is the rate state?  I see mine is set to something like 48, but I 
don't know what it is.

again, what is this?

I have my amp connected there, and the headfones plug into that.  I'll get 
a headfone amp next year, for now, I've spent all that I had, plus 
more.... which is one reason why the problems are so frustrating.

last night I got them!  I reset the CMOS, rebooted, and fiddled here and 
there trying to get the audio card onto IRQ10 (well, anything lower than 
the 18 thsat it seems to end up with all the time), and when I later 
started envy24, there were the buttons!   now with your help I'll be able 
to set them up correctly at last.  (recording bass parts tonight!)

thanks man, I really appreciate it.

I will do this.  figured out how to do screen captures, and got my modem 
working too.  AND got rid of that dark colour set and customized the 
'classic' settings to suite my vision.

if anyone has (more) suggestions for fixing this I'd be happy.   it seems 
to me that even though the BIOS knows that I want it to use IRQ10 (I can 
set it in CMOS, and it tells me that there is a multimedia device in that 
slot, and a USB hub), when Fedora starts it runs an ACPI setup service 
which changes everything. is there a way I can tell ACPI what to do?   
the BIS appears to be quite limited for example I cannot find a latency 
setting there, which I have seen in other bioses.

would you like to see dmesg output?  /var/log/messages?
should I try disabling hyperthreading and running the nonsmp kernel?
I'm starting to think that adding another stick of DDR2 RAM might help, 
since with only one stick it is not running in double data rate mode, says 
so during boot.  or maybe a second harddrive?  the only spare I've got is 
IDE and surely that is a waste of time since SATA is faster?

HOWEVER, when tracking violin yesterday I got many xruns, even though I 
was recording one track and playing back one other.  I could hear glitches 
in the played back guitar track!  at least the violinist didn't complain.
what will happen when I track 4 channels for drums?!
