[PlanetCCRMA] delta 410 lag and bad latency

[patrick]

hi all,

my delta 410 doesn't seem to work fine on my system, ie:
i have a 2-3 seconds of lag (no sound) everytime i open an audio 
software or change an effect in ecamegapedal. same thing when i open a 
patch in puredata. i'm able to use puredata for 5 minutes, but after i 
get: "DIO errors" and a lots of "watchdog: signaling pd..."

i tried with 2.4.23-1.ll.rh90.ccrma and 2.4.24-1.ll.rh90.ccrma. i tried 
with kernel.lowlatency = 0 and kernel.lowlatency = 1: no difference 
(even for latency in pure data = 200 ms) - it can do better right?

-----------------------------------STARTUP ALSA--------------------------
/etc/init.d/alsasound start

is this normal: when i stop alsa (/etc/init.d/alsasound stop) i'm still 
get sound from S/PDIF In? and then, if i open qjackctl the sound stop! 
some screenshot of my configuration in envy24control - it's strange, i 
have multiple S/PDIF In and also 2 H/W Out 8(R) (envy24full.jpg)? can i 
fix this, how envy24control get those informations (from asound.conf)?


i know this is a lot to ask, but who knows.
patrick
