thanks! couldn't find that for whatever reason. improper googling i guess.
but after the rest of this discussion i guess that isn't the problem 
either, as it only shows up on jack's boot. (...eew..)

at this point i don't think it's the system software parts. i'm just 
trying to get a stereo sound out cleanly!
  i have been reading alot - most of the time that i should be making 
music - and this computer (actually not the one i am typing on now) 
is a 2.4ghz P4 on a VIA mainboard with 768 MB ram, which seems fully 
capable. i installed the redhat planet-ccrma w/ capabilities 
ensconced, 2.4.20-20.1.caps.rh90. alsa has the proper drivers for the 
VIA82xx built-in sound and midi, the .asoundrc file is to that 
hardware, lsmod looks good, everything works, but the sound coming 
out is messed up with (cyclic, i believe) digital clicks and pops. 
almost tremelo! i've tried to configure all the things i can that i 
have read, (kernel, alsa, hdparm) - what's left is irq? - but i can't 
see how to change it. it seems to reside on IRQ 5 alongside the usb 
ports. i cannot physically move the sound card, it's built in. it has 
stereo mini-plugs i/o + line out plus spdif rca and optical. if i do 
lspci -vvv, while every other bus shows a line that states its 
latency (32 in most cases) the audio card does not have this line 
(??).

actually i haven't tried the spdif outs yet .. hmmm..

couldn't make this. liblatencygraph.a  has an undefined reference to 
gdImageGif   and it quits out its making.


whine whine whine, all i do is whine. thanks for help of any sort, 
lest i appear ungrateful for all the work to get me as far as i am 
now.
