[PlanetCCRMA] PAE kernel & Jack

[sevol]

Hi,

I haven't had luck getting the fcPAE kernel working right with Jack -
huge xruns with nothing connected to Jack, + no sound using midi with
that kernel. After days of googling, tweaking, & testing, I only
accomplished making Jack unable to start. I was thinking the PAE
enabled kernel was real time, too, but that assumption might be wrong,
or is it? I've tried changing the periods to 512, 1024, & 2048, &
changing nperiods to 3 & 4. Doesn't help. Since I haven't a clue any
more, I've reverted to the ccrmart kernel & will live with not
accessing all my ram for now.

Also, when I researched & bought the motherboard I didn't pay
attention to the onboard soundcard because I have 2 firewire cards
(neither quite working ATM), & planned to use one or the other. Until
then, I hoped to do some experimenting with Linux software & the
onboard card. (With the ccrmart kernel I'm having another audio issue
- grainy sound output - preventing much use. That I'll take up
elsewhere.) This is all to say, I don't know if any of the problems
have to do with my onboard soundcard being a Realteck ALC882 using the
HDA Intel driver.

I could easily have overlooked a simple solution. If anyone sees
something I've missed, please let me know - I've never been able to
get a actually working Linux audio system going, but still hope to.
Even as it is, thank you for taking the time to packag the PAE kernel
Fernando.
