[linux-audio-user] determining source of latency (system info included)

[Nick Salamander]

i am experiencing the "system can't keep up" messages
like crazy, even recording a single first track.

often when i speak into the microphone, what comes out
of the speakers sounds like it has a crazy chorus
effect on it.

i also wonder what the correct settings to use in the
alsamixer gui are.

below is some system info gleaned from a modified
shell script somebody posted on another list.

if anyone has any ideas please let me know!  and if
there's any other system info i could provide. 
thanks!
