Nope, it's not a DSSI problem, it's a problem with the plugins I've  
written and at least one (wsynth) based on my code.  Not a strange  
bug, just your garden-variety ethnocentrism of an English-speaking  
programmer....

The fix is to temporarily set a neutral 'C' locale while saving and  
loading the patches.  I'm working on patching whysynth now, but I'm  
in the middle of exams so it might be a week or three before I get  
them all released.  Thanks for the report,

Kernel-rt support for Ndiswrapper broken

Hi,

with high hopes I installed the new kernel
(2.6.26.8-1.rt16.1.fc10.ccrma.i686.rt) and associated development
packages. Unfortunately I still have the same trouble as with the
earlier versions. Support for Ndiswrapper is broken.

Ndiswrapper 1.54 compiles nicely and the module installs as should.
After a reboot network comes up and the WLAN connection works as
expected.

The trouble starts when I start my internet radio. After about ten
seconds of streaming audio the WLAN connection dies and the only way to
resurrect it is to reload the ndiswrapper module and restart network
service. With occasional packets transferred back and forth like in
average network surfing this problem does not appear. Streaming is
impossible.

Used software:

FC10 (2.6.26.8-1.rt16.1.fc10.ccrma.i686.rt
Ndiswrapper 1.54
Auqualung
Rhythmbox

HW:
3 GHz P4
1 GB RAM
SMC 2802W V2 PCI WLAN card

Cannot set keyboard in Gnome, running via VNC in FC10

Hi
I have searched for this and find things related but not exactly the same. At least not with recent versions.
I want to setup my computer without screen and instead run it via VNC from my laptop.
I had it working with FC7 but that setup is now gone. I now have a fresh install of FC10 and have just made an update.
When I start vncserver and log in from a remote client I get an error dialog saying: Error activating XKB configuration.
I get the gnome desktop but I am not able to set my keyboard layout and type to mach the hw I have.
Please advice
(I know this is not a pure PlanetCCRMA question but I'm stuck and you guys are always helpful)

Wondering about upgrading my CPU

Hi Everybody,

I've been struggling with recording on Linux for a while now, and at last I seem to be getting close to where I
want to be.  

I'm using Fedora core 10, PlanetCCRMA apps, ardour-2.8-1.fc10.i386, ffado-2.0-0.6.rc1.fc10.ccrma.i386
libffado-2.0-0.6.rc1.fc10.ccrma.i386, a Focusrite 10 26,  qjackctl-0.3.4-1.fc10.i386,
jack-audio-connection-kit-1.9.2-2.fc10.ccrma.i386.  I'm using the edge kernel because my
motherboard is an ASUS P5QL Pro, which doesn't work with the 2.6.27 kernels.  So far so good.  

My hardware includes the focusrite IO 26 and a Behringer BCF2000 control surface, which is particularly
helpful as I am visually impaired and have trouble with the small mouse pointer and the small print used in
Ardour.  

My problem is that I'm still getting xruns.  I use the lightweight window manager XFCE, and I shut off network
services when I am recording, (NetworkManager, sshd, ntpd, vsftp, httpd, etc.  This all helps; sometimes
I can record at pretty low latencies with no xruns.  But not always. 

Oh, here's an example of how I call jackd:

/usr/bin/pasuspender --s | /usr/bin/jackd -R -P70 -t5000 -dfirewire -r44100 -p128 -n3 &

Yes, I can set -p higher, but I've experienced xruns recording, say 4 or 5 mics in ardour at even -p512 or
-p1024.  

I do understand that there is quite a bit of trial and error involved in trying to find the best settings for
jackd, and I've tried many different -p and -n settings to see if I can find some low latency with no xruns.  

My CPU is an inexpensive Pentium D (although I believe it is running at 3 Ghz).  I'm wondering what I can expect
if I upgrade to, say, a relatively fast Core 2 duo or a quad core CPU.  Does anyone have information about how
this might affect my situation?  My understanding from years back is that the Linux kernel does a good job at
taking advantage of multiple CPUs, and presumably, multiple cores, so I am hopeful that a newer, faster
CPU might solve my latency and xrun issues. 

Your thoughts and comments would be appreciated.

This seems kind of obvious, but did you try simply connecting the input 
from whatever channel you're coming in from directly to jack outs (in 
jack's connection window)? This will eliminate any software in the 
middle that can be causing problems.

Have you tried setting up the Keyboard directly first and after that
VNC in? I use a Japanese keyboard and VNC into my FC10 box from my
office and it works fine. However, I did setup the Keyboard before I
used VNC. I didn't do anything special with the VNCserver or the VNC
client I use. I actually VNC in with different keyboards(English and
Japanese), but it always takes the Japanese layout since I first setup
the system using it. Lucky in my case there are few key that are
different and I have remembered what they are. That is something I
have just come to live with since you have to manually set the
keyboard layout anyway even on different OSes.

I really don't think you should get xruns at 1024 frames per period.
I used to record 4 mics on a 1.8 GHz Athlon XP with 1GB RAM with no
xruns.  That was with a PCI card; I'ved never used firewire.

Some other things to look at:  run "/etc/init.d/rtirq status" and
check the rtprio of your firewire chip.  I like to set the rtprio of
jack just below that of my audio device, but above anything else.
Yours is 70, which on my system is the same as one usb port and the
graphics chip.

Use hdparm to make sure your drives are running their best (search for
articles on how to do this).   Although this isn't usually necessary
any more, especially with SATA drives.

You could also check your PCI latency timer values using lspci.  Try
setting the value to the max for your firewire chip.  See
http://www.ibm.com/developerworks/library/l-hw2.html.

One day I want to write troubleshooting shell script to check all this stuff.

Maybe the ffado project has more info?  Maybe you have a crappy
firewire chipset?

Re: Kernel-rt support for Ndiswrapper broken


The 2.6.29 ccrma test kernels seem to be missing something that keep 
the akmod from building, so remove all the dot 29 test kernels and use 
the 2.6.26 kernel that you had listed in your original post.

I am not a pro on this kernel stuff, but nvidia has worked without any 
problems since I started using the akmods.  However, I couldn't get 
the broadcom akmod to activate my wireless, (it could have been a 
configuration issue on my part), and fwcutter has always worked great 
with my broadcom wireless adapter.  And I hope the issues with akmod 
and the dot 29 kernels gets worked out before ccrma moves to F11.

Good Luck,
Jeff
