Hi
Quick intro: Today I was on stage with my ubuntu laptop, running jack
and renoise. Suddenly (during sound check) renoise started acting really
strange, and things started getting a it hectic. After a
last-resort-reboot I realized that the firewire cable to my soundcard
had come loose.
So now I did some testing, and unplugging the firewire cable doesn't
give any error messages, which I find strange. Is there a way to make my
system more informative in such situations?
NB: I should mention that plugging the cable back in, killing +
restarting jack solves the problem. But of course that requires you to
realize what went wrong :-)

Hello everyone,
To my surprise, jackd could not start this morning (using
qjackctl).
User name was added to the audio group. The audio devices are:
% cat /proc/asound/cards
0 [PCH ]: HDA-Intel - HDA Intel PCH
HDA Intel PCH at 0xf7d10000 irq 53
1 [M1010LT ]: ICE1712 - M Audio Delta 1010LT
M Audio Delta 1010LT at 0xd040, irq 18
Interface in qjackctl is specified as 'hw:M1010LT'
Here's what happened:
Sun Mar 31 07:37:23 2013: JACK server starting in realtime mode

So I tried with 'hw:1' from the drop-down menu:

What could be the cause of this problem ? - thanks !
ok, I have installed all of the libs (lilv, sratom, suil, jalv ...)there
are my messages (sorry for huge data..):

Can someone who keeps up with RT development help me find up to date
information?
There do not seem to be any RT patches for 3.8 in the usual place (which
as far as I know is still
https://www.kernel.org/pub/linux/kernel/projects/rt/ ).
I found a message from Fernando several months back mentioning that there
was some kind of NFS bug in the 3.6-RT kernel, which is why CCRMA kernels
are still based on 3.4, but despite searching lkml.org with various words
and phrases, I have not been able to piece together any coherent
information on the current state of 3.6 RT kernels, and why there is yet
no 3.8 patch set.
Is this just a case of the RT development community being rather small, so
no one sees a need to make an announcement to LKML that 3.8-RT has some
problems, so don't expect an RT release very soon after the mainline 3.8
release? Or am I just looking in the wrong places for information?
thanks,
Chris Caudle

I'm fairly sure your m-audio card is at hw:1 in this case. There's no
guarantee in which order the cards end up at each boot.
To make sure you always start your m-audio card, I usually always use the
name. Instead of hw:0 I would use hw:M66. You can get the name from
checking the file /proc/asound/cards as I do below
$ cat /proc/asound/cards
0 [SB ]: HDA-Intel - HDA ATI SB
HDA ATI SB at 0xfe300000 irq 16
1 [M66 ]: ICE1712 - M Audio Delta 66
M Audio Delta 66 at 0xd040, irq 21
2 [NVidia ]: HDA-Intel - HDA NVidia
HDA NVidia at 0xfe080000 irq 24

This means you don't have realtime privilege. You need to do two things.
First, make sure you have a file called /etc/security/limits.d/audio.conf
with the contents (if you didn't enable realtime privilege during install,
the file will be named /etc/security/limits.d/audio.conf,disabled):
# Provided by the jackd package.
#
# Changes to this file will be preserved.
#
# If you want to enable/disable realtime permissions, run
#
# dpkg-reconfigure -p high jackd
@audio - rtprio 95
@audio - memlock unlimited
#@audio - nice -19
Second, add yourself to audio group. You can do this with the command:
sudo usermod -a -G audio $USER
Then, reboot for changes to take effect.

So, these errors have nothing to do with the kernel. A realtime kernel
does not provide realtime privilege.
You accidentally sent this mail directly to me ;)
Hi everyone,
Is it possible to have musical audio creativity as we know it (jackd,
Ardour, etc..) in a Linux VM that runs under Windows 7 ? Is it possible
to connect a HW synth to jackd in such a setup ? Just asking before
starting to do anything - thanks !

Wow, thx for your wikipedia contribution ;)
The bcr2000 has rotary encoders with LEDS.
The bitstream 3X does have potentiometers and it's possible to set the
3X in such a way that the know has to pass the value of an control in a
certain software, before it gets 'on'.
Potentiometers seems to have the advantage of being more accurate and
have a more analogue feel.
The question is whether the X3 is good for controlling softsynths like
AMS / Ingen and stuff like SuperCollider. Or are rotary encoders better
for this.

Hello everyone!
I want to buy a second soundcard. I had considered getting another MAudio
Delta 1010LT, since they are just perfect. But someone alerted me to the
thought, that PCI is slowly dying and it might not be such a good idea to get
another piece of equipment, that might no longer be supported with the next
board.
Right: E-MU 1212m Anyone got one, has experience with it?
If not: I want something multi channel with analog I/Os, at least one S/PDIF
or wordclock to sync it to my Delta and create a big virtual soundcard. Price
limit is about 250 EUR.
Last remakr: Ihave ssen the note about E-MU 1212m card on alsa-project, its
usabilityis unknown/not tested yet (officially).
Any advse is welcome.
Warm regards
Julien
