[PlanetCCRMA] Lost in the backroads..

[Jeff Farr]

Ok, thanks for the help. I had a feeling alot of this is total newbie stuff,
I'm searching the archives, but there is so much to learn (I'm new to linux
in general) that I'm moving in circles alot. So, I start jack using jackd,
but now when I open jackRack I get the message "Cannot open ALSA sequencer,
No such file or directory". Should the terminal that I start jack in not go
back to a prompt (ie: right now it is stopped on "nperiods = 2 for
playback")? things like alsaplayer won't run untill I close the terminal
with jack running. apt-get install planetccrma-core and
planetccrma-audioapps is what I used, and it shows that I have the latest
version. However, I haven't been able to find some programs like KConnect
and QJackConnect. I should mention that there is an on board sound card, but
I have it disabled in the bios. Is this possibly getting booted as the main
device (I would doubt this as envy24control and the other mixers bring up
the interface for the Delta). I'm also doing a parallel install on a Dell
Latitude C600, and that is working a bit better, however, there are alot of
pops and clicks, I assume ALSA configs are the place to look to fix this,
but again I am a bit lost on how to do it.

How do I go about checking that alsa is properly installed? Also, snd cased
my computer to lock up earlier today when I attempted to record, I could
open a file but clicking on the play button in the lower right had no
effect. Trying to play a file in Helix brings message "unable to open the
audio device, another app may be using it" when I open a file.
