I'm stumped.
I have two problems
1. I can never get two sound processes to work at once. If I have xmms
running, jack will refuse to start with this error
ALSA lib pcm_hw.c:1155:(snd_pcm_hw_open) open /dev/snd/pcmC0D0p failed:
Device or resource busy
the playback device "hw:0" is already in use. Please stop the
application using it and run JACK again
cannot load driver module alsa
This shouldn't happen because the sounblaster can do it fine
2. And the weirdest thing of all. All the playback of music is too fast!
I'm sure of it. All my mp3s are seemingly playing ever so slightly to0
fast so that the pitch is raised and it sounds crazy. It seemed so odd
that I timed an mp3 with my stop watch and on the player it says that it
runs for 4min 05s when in reality it runs for 3min 48s . That kind of
difference is not a good thing. The playback is also stuttery at times
which is totally unusual for my system.
Seriously, Avril Lavigne doesn't sound that great at increase speed.
I could really do with some help.

Hey,
In the ongoing attempt to eliminate xruns, I've set
Option "no_accel" "yes" in the XF86Config.
Watching the screen redraw is like a valume overdose.
I've done this without really knowing why it will help
or whether it has. Assuming that it has helped, I
probably have to live with it.
I am using Planet CCRMA with KDE and have a runlevel
for Desktop work and another for audio work. I boot
into runlevel 5 and then use telinit to switch to 3.
Is it possible to specify xf86config files for each of
these runlevels?
Or is there another method for a user to turn
acceleration on and off?
Is anyone else turning off acceleration and how do you
deal with the performance?

Hello fellow linux audio users :)
I'd like to get suggestions of available and working midi control
boards: interface with faders, knobs, possible vu meters that's suppose
to control computer software. I'm thinking of faders in Ardour, and all
kinds of thinkable applications in pure-data and supercollider.
I've seen the BFC-2000 looks promising but why an USB interface anyway?
How does fader control of Ardour work? In pure data, i can imagine how
it would/should work: just sort out the desirable midi message [ctlin]
and do something with it.
I'm sure there are less expensive options than behringer - any
suggestions both cheep and expensive are welcome.

Hi Hans,
What a great question. Normally, I do metered recordings and do what you
said we shouldn't do, namely edit the tempo track, but I don't use the
metronome because it seems to discourage any expression at all (to me anyway).
When editing a tempo track, I find it essential to have a quick and
easy way to emit dozens of MIDI messages and also to erase and redo them
quickly. I don't edit this type of track one step at a time. It's too
hard to get it to sound right.
For non-metered recordings, I simply don't do any loops at all. The
assumption behind this approach is that non-metered recordings should not
have identical loops. Once in a while I make an exception and have perhaps
two or three very long loops, but these are relatively easy to handle.
So at the beginning of any new composition, I ask myself: To meter or
not to meter? It's a tough question. Essentially it means: To loop
or not to loop?
I'd be interested in hearing from others, also, and thanks to those who
already did reply.
Regards to everyone,
Dave.
hi :)
I recently noticed that there's a JACK plugin for ALSA. Is it actually
being used by anyone? Does it work?
Because the only thing I could get to work with it was aplay. With
everything else I get only noise or nothing at all.
Hi,
I have a HP Compaq nx7000 laptop, using Gentoo and vanilla 2.6.8.1
patched with VP (P9) + realtime-lsm patches.
(2.6.8-gentoo-r3 + realtime-lsm, same problem..)
By running jackd -R -d alsa my box freezes (or stops responding).
jackd -d alsa runs ok though. Jack is version 0.98.1 (0.99 also tested),
and no NPTL in glibc. Used alsa driver is intel8x0.
Where would it be best to start troubleshooting..?
Any help would be appreciated. :)

Hi,
Is your processor hyperthreading (and running an smp kernel)? I
remember people having terrible lockups when running jack realtime with
hyperthreading cpus and 2.6.8*. It's quite a bit better (very few
issues so far) on a dual-proc smp machine, but cdburning freezes it
under that kernel.

This may be semi-OT for this list but it does relate somewhat in
regards to burning CDs and eventually using the 2.6 kernels for low
latency audio, etc.
My production distro is a Planet CCRMA RH 9 installation. I also
have an installation of FC2 that I use for graphics and will
eventually be migrating to. For me, using FC2 and the 2.6 kernels
is edgy enough -- I don't have enough knowledge and experience to be
much use as a beta tester.
With those caveats in mind, is there a particular 2.6 kernel that
would be better than either 1) the kernel that was shipped with my
FC2 disks, or 2) the most recently released kernel (2.6.8-1.521)?
Where can I find more info about the various kernels and other
updates as they are released? Does anyone have any advice as to an
FC2 update strategy other than running `# yum update` every week
or so?
Thanks,
Barton
Hi All,
Does anyone know of an application that will automatically select a stream
from a set of streams that I define, depending on (for instance) there is
a certain level of data coming from the stream in question ?
I'm looking for something that can handle streams from an internet site,
rather than just file based.
I'm not particularly bothered where it hooks in to the entire Sound Stack -
ALSA, arts, etc, I can work that easily enough myself.
I've looked at the feature lists of applications such as like Ardour
(http://ardour.soureforget.net/), ProTux (http://www.nongnu.org/protux/),
and Audacity (http://audacity.sourceforge.net) have, and they don't quite
seem to do what I need, and they seem to be file based, rather than
internet stream based.
It would be nice if it also had a good (and 'proper') scope associated
with it, similar to those shown in the screenshots for the aforementioned
Ardour, ProTux, Audacity, and Baudline (http://www.baudline.com).
However, if anyone knows of a standalone scope of that ilk, that would
tap into either arts, or ALSA output, that would also be great.

Shhhhhhh!
You can hear a pin drop! :)
I'm bored and trying to stop smoking! Any one got a "patch" for that??!
Someone start a ruckuss!
Just kidding.....
