Ardour crashing with error about not being fast enough.

by Brian Bergstrom

I have a project that I was working on in 2.3 and I started getting this error. JACK has either been shutdown or it disconnected Ardour because Ardour was not fast enough. Try to restart JACK, reconnect and save the session. It got the point where I couldn't work on the project anymore. I could open the project and playback my song, but as soon as I stopped playback that message would pop up and JACK would get Xruns. My session isn't extroidinary, it has 7 drum tracks that I recorded from Hydrogen, 2 guitar tracks and a bus. It has 7 effects running which doesn't seem like a lot since I have run more effects in Abelton Live and Adobe Audition before. I investigated and tried to make sure my system was tweaked correctly. I am running Ubuntu Studio Hardy with real time kernel 2.26.24. I have my audio group setup in the limits file with unlimited memlock. My system has a 1.8GHz Core Duo and 2GB of ram. I don't have any hefty daemons/processes running. I am using a Edirol UA-4fx USB audio interface. I have jack setup with 128 frames and 3 periods. I got the same results when I turned the frames up to 1024. Ardour plays/records fine in a new session with just a few tracks. Other audio apps work fine with Jack. I built .116 jack and 2.7 Ardour from source with optimize flags and still get the same result. My hard drive is running in udma6 mode and gets 900MB/sec cached read and 40MB/sec buffered disk read. I have run the realTimeConfigQuickScan.pl from http://wiki.linuxmusicians.com and all checks are good. I am out of ideas and just want to make music, any help is greatly appreciated. Thanks.

where is Packman's Jack 0.116 package for OpenSuse 11.0?

by Hector Centeno

Hi, Does anyone know if the latest Jack and Jack2 packages will be back any time soon to the Packman repository? Right now the only available is the outdated one from the OpenSuse repos (ver. 0.109). Does anyone know other OpenSuse 11.0 repository where to find it? Cheers, Hector

I've changed the driver to use a hard-coded sample format for the UA-20. This should be on the public CVS servers in a hour or so. HTH Clemens Thanks Nicola Lunghi

Experience with M Audio Fast Track Pro USB interface

by Nicanor Garcia

Hello. I've in the GNU+Linux world since last december and though I don't know a lot yet, I'm really excited about working with it and I don't wanna' downgrade to windows never again. Now I'm planning to get a sound card, and I found the M Audio Fast Track Pro (http://www.m-audio.com/products/en_us/FastTrackPro.html), which has all the features I want. But I'm not sure to buy without knowing its compatibility with Linux. I now this card isn't on the ALSA list, but I've read a lot of articles about this card being somewhat hard to set up, but still usable. But I don't know how the card behaves after installation, if it is fully operational and a good choice. If anyone can tell me his/her experience with this card I would be greatly thankful. For more info, I'm planning to use Studio 64. Thank you very much. Saludos From Colombia.

Recording multiple instruments at once? [OT?]

by James Stone

Hi there, I was wondering if anyone has recommendations for a reasonably cheap USB interface to record a band live (so multiple inputs from the different instruments). I guess some kind of mixer would be nice, but a sound card with 6 inputs would be fine. James

Re: [LAU] [ANN] jack_capture V0.9.32

by hermann meyer

Oh it's simple, just let it look like that: INSTALLPATH=$(DESTDIR)/usr/local/bin/ In the case $(DESTDIR) isn't set, it would'nt influence the installation, if a package-builder use the makefile, the installation go's in the package to $(DESTDIR).

using a condensator microphone live

by Atte André Jensen

Hi Sorry for the OT question, but I hope this list would provide me with valuable input. I'm using my sE usb2200A 48V microphone in my home studio, but now I'm considering using it live for lead vocals. Is that gonna be problematic, I'm (naturally) mostly worried about feedback? We're using headphones for monitor, but the house PA might cause problems. When recording vocals at home the singer is normally about 5 cm from the mic, was planing on the same approach live... Oh, and would getting a reflexion (http://www.sweetwater.com/store/detail/Reflexion/) make any difference? Any ideas and especially experiences with using microphones like this in a live setting are more than welcome. -- Atte http://atte.dk http://modlys.dk

by Kjetil S. Matheussen

Downloads: http://archive.notam02.no/arkiv/src/?C=M;O=D http://folk.uio.no/ksvalast/arkiv/src/?C=M;O=D jack_capture ============ jack_capture is a program for recording soundfiles with jack. Its default operation is to capture whatever sound is going out to your speakers into a file, but it can do a number of other operations as well. 0.9.31 -> 0.9.32: *Changed default format for from wav to wavex for files with more than two channels. Thanks to Fons Adriaensen for the suggestion. *Added fix for 64 bit mode. Thanks to Andras Simon for helping to find the bug and Dominique Fober for fixing the bug. *Added the "-verbose" option for easier debugging in case program crashes or freezes. *Checks whether sndfile.h exists before generating setformat.c.

Jack Crashing

by Steven Tonge

Hi, I'm having trouble with Jack on a Dell D420 laptop. Sound is configured and plays fine but when I start jack I get regular xruns and then it crashes after about 30 seconds. If I start and audio app, I can see it appear in the connections, but no sound plays and then when jackd goes down, it complains about a broken pipe. I'm totally stumped. Its not a problem with the frames/period as I've tried all different combos (up to 1024 frames/period with 8 periods per buffer) All that is displayed in Any ideas? lspci reports: 00:1b.0 Audio device: Intel Corporation 82801G (ICH7 Family) High Definition Audio Controller (rev 01) lsmod reports: snd_rtctimer 4640 1 snd_hda_intel 346136 3 snd_pcm_oss 42400 0 snd_mixer_oss 18048 1 snd_pcm_oss snd_pcm 78852 2 snd_hda_intel,snd_pcm_oss snd_page_alloc 11400 2 snd_hda_intel,snd_pcm snd_hwdep 10628 1 snd_hda_intel snd_seq_dummy 4868 0 snd_seq_oss 35968 0 snd_seq_midi 9376 0 snd_rawmidi 25632 1 snd_seq_midi snd_seq_midi_event 8576 2 snd_seq_oss,snd_seq_midi snd_seq 54992 10 snd_seq_dummy,snd_seq_oss,snd_seq_midi,snd_seq_midi_event snd_timer 24836 3 snd_rtctimer,snd_pcm,snd_seq snd_seq_device 9612 5 snd_seq_dummy,snd_seq_oss,snd_seq_midi,snd_rawmidi,snd_seq snd 57636 20 snd_rtctimer,snd_hda_intel,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_hwdep,snd_seq_dummy,snd_seq_oss,snd_rawmidi,snd_seq,snd_timer,snd_seq_device soundcore 9312 1 snd /usr/bin/jackd -v -R -p1024 -t5000 -dalsa -dhw:0 -r44100 -p1024 -n8 gives: getting driver descriptor from /usr/lib/jack/jack_freebob.so getting driver descriptor from /usr/lib/jack/jack_oss.so getting driver descriptor from /usr/lib/jack/jack_alsa.so getting driver descriptor from /usr/lib/jack/jack_dummy.so jackd 0.109.2 Copyright 2001-2005 Paul Davis and others. jackd comes with ABSOLUTELY NO WARRANTY This is free software, and you are welcome to redistribute it under certain conditions; see the file COPYING for details JACK compiled with System V SHM support. server `default' registered registered builtin port type 32 bit float mono audio registered builtin port type 8 bit raw midi clock source = system clock via clock_gettime loading driver .. new client: alsa_pcm, id = 1 type 1 @ 0x805a4c0 fd = -1 apparent rate = 44100 creating alsa driver ... hw:0|hw:0|1024|8|44100|0|0|nomon|swmeter|-|32bit control device hw:0 configuring for 44100Hz, period = 1024 frames (23.2 ms), buffer = 8 periods ALSA: final selected sample format for capture: 32bit little-endian ALSA: use 8 periods for capture ALSA: final selected sample format for playback: 32bit little-endian ALSA: use 8 periods for playback new buffer size 1024 registered port system:capture_1, offset = 4096 registered port system:capture_2, offset = 8192 registered port system:playback_1, offset = 0 registered port system:playback_2, offset = 0 ++ jack_rechain_graph(): client alsa_pcm: internal client, execution_order=0. -- jack_rechain_graph() 7314 waiting for signals new client: alsa-jack.jackP.7319.0, id = 2 type 2 @ 0xb7edd000 fd = 10 registered port alsa-jack.jackP.7319.0:out_000, offset = 12288 registered port alsa-jack.jackP.7319.0:out_001, offset = 16384 ++ jack_rechain_graph(): client alsa_pcm: internal client, execution_order=0. client alsa-jack.jackP.7319.0: start_fd=5, execution_order=0. client alsa-jack.jackP.7319.0: wait_fd=7, execution_order=1 (last client). -- jack_rechain_graph() connect alsa-jack.jackP.7319.0:out_000 and system:playback_1 (output) ++ jack_rechain_graph(): client alsa_pcm: internal client, execution_order=0. client alsa-jack.jackP.7319.0: start_fd=5, execution_order=0. client alsa-jack.jackP.7319.0: wait_fd=7, execution_order=1 (last client). -- jack_rechain_graph() connect alsa-jack.jackP.7319.0:out_001 and system:playback_2 (output) ++ jack_rechain_graph(): client alsa_pcm: internal client, execution_order=0. client alsa-jack.jackP.7319.0: start_fd=5, execution_order=0. client alsa-jack.jackP.7319.0: wait_fd=7, execution_order=1 (last client). -- jack_rechain_graph() jackd watchdog: timeout - killing jackd Thanks Steven -- The University of Edinburgh is a charitable body, registered in Scotland, with registration number SC005336.
