Hi,
there are 2 things I don't understand.
1. Linux-Rt and TSC
===================
All Rt kernels for all Linux distros I use seem to have an issue
regarding to TSC.
I wonder what to do, to get rid of those messages, IOW how to fix the
issue.
E.g. Debian 32-bit architecture
root@debi386:/mnt/arch/home/rocketmouse/Desktop# dmesg | grep TSC
[ 0.000000] Fast TSC calibration using PIT
[ 0.000000] Marking TSC unstable due to TSCs unsynchronized
root@debi386:/mnt/arch/home/rocketmouse/Desktop# grep TSC /var/log/messages
Jan 16 09:28:08 debi386 kernel: [ 0.000000] tsc: Fast TSC calibration using PIT
Jan 16 09:28:08 debi386 kernel: [ 0.000000] tsc: Marking TSC unstable due to TSCs unsynchronized
Jan 16 09:28:08 debi386 kernel: [ 0.003000] calibrate_delay_direct() ignoring timer_rate as we
had a TSC wrap around start=4287833042 >=post_end=13864416
Jan 16 09:50:58 debi386 kernel: [ 0.000000] tsc: Fast TSC calibration using PIT
Jan 16 09:50:58 debi386 kernel: [ 0.000000] tsc: Marking TSC unstable due to TSCs unsynchronized
Jan 22 12:05:33 debi386 kernel: [ 0.000000] Fast TSC calibration using PIT
Jan 22 12:05:33 debi386 kernel: [ 0.000000] Marking TSC unstable due to TSCs unsynchronized
Jan 22 are messages when booted to kernel 3.2.0-4-rt-686-pae i686 from
the repositories.
Jan 16 might be a broken kernel 3.8.13-rt14-pae-rocketmouse I build
based on a 3.8.13-rt14 x86_64 config.
E.g. Arch Linux 64-bit architecture
On startup I see "x86 Rt requires FEATURE_CONSTANT_TSC" or similar for
Arch Linux Rt kernels from the repositories and for the once I build.
This link for Chromebooks was the best explanation I found:
http://www.chromium.org/chromium-os/how-tos-and-troubleshooting/tsc-resynch…
root@debi386:/mnt/arch/home/rocketmouse/Desktop# grep tsc /proc/cpuinfo
flags : fpu vme de pse tsc msr pae mce cx8 apic sep mtrr pge
mca cmov pat pse36 clflush mmx fxsr sse sse2 ht
syscall nx mmxext fxsr_opt rdtscp lm 3dnowext 3dnow
extd_apicid pni cx16 lahf_lm cmp_legacy svm extapic
cr8_legacy 3dnowprefetch lbrv
flags : [snip] tsc [snip]
2. Linux-Rt and IRQ allocation
==============================
All kernels I used in the last years for *buntu, Debian and Arch Linux
<= 3.8.13-rt14 (kernels > 3.8.13-rt14 don't work on my machine) give my
graphics it's own IRQ, the Debian kernel 3.2.0-4-rt-686-pae doesn't.
What options do I need to enable, so that it will allocate the graphics
it's own IRQ too, instead of sharing it with the RME card?
Regards,
Ralf
Hello all,
AFAIK the Focusrite Scarlett 18i8 USB interface works on Linux.
* Can anyone confirm this ?
* Should it work with a Raspberry Pi ?
TIA,

Hello LAU,
I'm happy to announce my first bandcamp released mini album/EP named "Four"
It consists of four calm and meditative tracks I made around 1990 using a Fostex X-15 four track cassette recorder.
Listen to it at http://edogawa.bandcamp.com/album/four
Per se this music hasn't got anything to do with linux audio, except being digitized under linux, nevertheless I see myself also as linux musician these days, so I hope it's ok to post that here.
For the flash-less I can supply a link to my dropbox, https://dl.dropboxusercontent.com/u/42502696/musik/Four/index.html
I'm curiously awaiting your feedback, and I hope you enjoy!

Cleaning out hard drives again.
Found this little gem, covered with obvious mistakes, (which is why it was never really published) but still interesting if you like weird jazz in odd meters:
http://storage.restivo.org/music/Cronies/suite-2007-11-06.ogg
Linux content is all the keyboards, which are: fluidsynth, two crazy AMS patches, jconv, jack-rack, etc.
Warning: it's 18 minutes long.
Part of it is in 11/4. There's also a nice windshield wiper moment where 3 bars of 5/4 are overlaid on 2 bars of 5/4.
The end of this epic beast consists of a cover of "Morning Bell" by Radiohead.

I just installed ardour3 64bit-3.5.308-dbg. The installation
showed:
!!! WARNING !!! - The version of Jack on this system is too
old! Using an old version of Jack is not recommended. Please
update Jack for best results.
System Jack version:
Recommended minimum versions:
Jack1 - 0.121.3
Jack2 - 1.9.8
But then the following is installed:
% dpkg -l | grep jack
(other bits removed)
ii jackd 5
ii jackd2 1.9.8~dfsg.4+20120529git007cdc37-2ubuntu2
Is there any problem ?
Hello,
Since some time now the Freeverb in Ardour3 (I mean, not included with
Ardour, but used by) interface does not allow the control of some
sliders. Also, the sound does not seem so good as soon as it is
included in the post-fader chain. cmt 1.16-1. For that matter, I
tried the TAP Reverb yesterday and found it sounded OK. Mayve freeverb
is not as good nowadays ?
Here it is, played live:
https://vimeo.com/78583355
I was playing playing bass and keyboards simultaneously there; our bass player had another gig that night. My Linux laptop was behind me, not seen; this was after I'd set up the MIDI keyboard to control all the synths. But it was right before I set up buttons on the Novation to switch patches quickly, so I was twiddling knobs to cycle through them.
Synths/tools played in the video are fluidsynth, jack-rack, jconv, many LADSPA plugins, nekostring, and AMS.
We were set up on stage wrong; the drummer and I couldn't see each other, which annoyed both of us, and there were all kinds of missteps because of that. But this is the best live video I have of that peice.
If you enjoyed the studio version, you might like the live version too.
