Subject: [linux-audio-user] determining source of latency (system info included)
From: Nick Salamander (sandroban_AT_yahoo.com)

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!
