[linux-audio-user] OT: cannot reach ardour.org

by Robert Epprecht

I know it is quite OT, but I have tried many other ways to solve the problem. Since ardour moved away from sourceforge I try to reach ardour.org and lists.ardour.org, but I can't. While list post from ardour-users did reach me for some time I got a message that I have been unsubscribed due to bounces. Whatever I try to reach them (confirmation mail, contacting listmaster, http, ping) gives me only errors. I have tried for more than two weeks now, but never reached them... I have no idea what might be wrong. Maybe ardour is on a blacklist or something? BTW: I'm living in Switzerland if that could matter. Can someone give me a *working* ardour URL or the IP of ardour.org or lists.ardour.org or any other help to solve the problem. Thanks a lot and forgive me to be off topic, Robert Epprecht

[linux-audio-user] Audio distortion with DMA enabled

by adam

Hi, I'm having problems with sound on my pc - a crackling sound. This only occours when DMA is turned on and there is ide disc access. It seems to be independent of the DMA speed. Also there is the same problem in windows with the manufacturers drivers. Here are my PC specs: Motherboard: Gigabyte GA-7VRXP Chipset: VIA KT333 / VIA VT8233A Onboard sound: Creative CT5880, Sigmatel 9721T CODEC (using alsa ens1371) I have also tried out another sound card (but with the same driver) with the same problems. I have heard that a BIOS PCI Latency setting can help this problem but cannot see this option in my bios. Thanks, Adam

[linux-audio-user] Latest HotPlug upgrade.

by David Baron

USB NEWS FLASH! The latest hotplug upgrade from SID now installs uhci-hcd without its being requested in /etc/modules. This module still does not unload correctly, however, so I guess I need to blacklist it so I can shutdown normally ... ugh--blacklisting this does not work (the original usb-uhci had been blacklisted as well and always loaded--at least ext3 is working!). The new hotplug loads a lot of stuff, in fact: dmesg | grep usb drivers/usb/core/usb.c: registered new driver usbfs drivers/usb/core/usb.c: registered new driver hub drivers/usb/core/usb.c: registered new driver hiddev drivers/usb/core/usb.c: registered new driver hid drivers/usb/input/hid-core.c: v2.0:USB HID core driver drivers/usb/core/usb.c: registered new driver snd-usb-audio drivers/usb/host/uhci-hcd.c: USB Universal Host Controller Interface driver v2.1 usb 1-2: new full speed USB device using address 2 snd-usb-audio: probe of 1-2:1.0 failed with error -5 snd-usb-audio: probe of 1-2:1.1 failed with error -5 drivers/usb/core/usb.c: registered new driver irda-usb drivers/usb/core/usb.c: registered new driver xpad drivers/usb/input/xpad.c: X-Box pad driver:v0.0.5 drivers/usb/core/usb.c: registered new driver audio drivers/usb/class/audio.c: v1.0.0:USB Audio Class driver drivers/usb/serial/usb-serial.c: USB Serial support registered for Generic drivers/usb/core/usb.c: registered new driver usbserial drivers/usb/serial/usb-serial.c: USB Serial Driver core v2.0 drivers/usb/serial/usb-serial.c: USB Serial support registered for IR Dongle drivers/usb/core/usb.c: registered new driver ir-usb drivers/usb/serial/ir-usb.c: USB IR Dongle driver v0.4 drivers/usb/core/usb.c: registered new driver usbnet drivers/usb/core/usb.c: registered new driver usb-storage (Those -5 errors apparently are not preventing the MIDI usb devices from operating. Can cat /dev/midi1 and see my key-presses.) However, the MIDI devices is the only one I have connected to one of the two (older system) USB ports. Should not hotplug load any of these other should I plug one of them in? I have no X-box, no dongles, no nothing.

Anyway, that still doesn't work. I've typed jackd -S -d alsa -r 44100 & but the prompt don't come back there's always a problem (xrun ...don't know what it's meaning) and when I try the jack metronome , jack_metro --bpm 120 &, the answer is : [moebius@localhost moebius]$ jack_metro --bpm 120 & [1] 2307 cannot connect to jack server [moebius@localhost moebius]$ cannot connect to default JACK server jack server not running?

[linux-audio-user] jack trouble

by C. Villard

Well, I'm always trying to get midi audio recording working, or at least just one of these :) ; well, I'm trying very hard but .... nothing's working ; I'm trying since a long time but ..... I have a P4 computer and mandrake 9.2 with a low latency kernel ( 2.4.22-21mm.2mdk). Well alsa is running and when I launch alsaconf, it says that my sound card is "intel 8x0 Silicon Integrated Systems [SiS] Sound Controller" (in fact, sound is integrated in the motherboard (an Asus P4S8X-X), and the motherboard doc says that the chip is an ADI AD 1980 6-channel audio codec) ; in an another place, I've also seen SiS 7012...... Alsaconf don't perform the last thing, playing a song 'cause something is missing : Loading driver... /usr/sbin/alsaconf: line 568: rcalsasound: command not found Setting default volumes... =============================================================================== Now ALSA is ready to use. For adjustment of volumes, please use alsamixer or gamix. Have a lot of fun! So I'm trying to launch jack and, as root, I type #jackd -d alsa -r 44100 and here is what I get : jackd 0.95.0 Copyright 2001-2003 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 loading driver .. apparent rate = 44100 creating alsa driver ... hw:0|hw:0|1024|2|44100|0|0|nomon|swmeter|rt|32bit control device hw:0 configuring for 44100Hz, period = 1024 frames, buffer = 2 periods Couldn't open hw:0 for 32bit samples trying 24bit instead Couldn't open hw:0 for 24bit samples trying 16bit instead Couldn't open hw:0 for 32bit samples trying 24bit instead Couldn't open hw:0 for 24bit samples trying 16bit instead And I'm obliged to do a Ctrl C to stop the process and Iget the mess : jack main caught signal 2 When switching verbose option for starting jack, jackd -vd alsa -r 44100, I get also thiese lines : new buffer size 1024 registered port alsa_pcm:capture_1, offset = 4096 registered port alsa_pcm:capture_2, offset = 8192 registered port alsa_pcm:playback_1, offset = 0 registered port alsa_pcm:playback_2, offset = 0 registered port alsa_pcm:playback_3, offset = 0 registered port alsa_pcm:playback_4, offset = 0 registered port alsa_pcm:playback_5, offset = 0 registered port alsa_pcm:playback_6, offset = 0 ++ jack_rechain_graph(): client alsa_pcm: internal client, execution_order=0. -- jack_rechain_graph() 5874 waiting for signals load = 0.0301 max usecs: 14.000, spare = 23205.000 load = 0.0474 max usecs: 15.000, spare = 23204.000 **** alsa_pcm: xrun of at least 0.912 msecs load = 0.0517 max usecs: 13.000, spare = 23206.000 **** alsa_pcm: xrun of at least 5.614 msecs load = 0.1184 max usecs: 43.000, spare = 23176.000 load = 0.0851 max usecs: 12.000, spare = 23207.000 load = 0.0705 max usecs: 13.000, spare = 23206.000 load = 0.0633 max usecs: 13.000, spare = 23206.000 load = 0.0812 max usecs: 23.000, spare = 23196.000 load = 0.0686 max usecs: 13.000, spare = 23206.000 load = 0.0666 max usecs: 15.000, spare = 23204.000 load = 0.0591 max usecs: 12.000, spare = 23207.000 load = 0.0554 max usecs: 12.000, spare = 23207.000 load = 0.0514 max usecs: 11.000, spare = 23208.000 load = 0.0515 max usecs: 12.000, spare = 23207.000 load = 0.0538 max usecs: 13.000, spare = 23206.000 load = 0.0635 max usecs: 17.000, spare = 23202.000 load = 0.0576 max usecs: 12.000, spare = 23207.000 load = 0.0783 max usecs: 23.000, spare = 23196.000 load = 0.0758 max usecs: 17.000, spare = 23202.000 load = 0.0766 max usecs: 18.000, spare = 23201.000 load = 0.0728 max usecs: 16.000, spare = 23203.000 **** alsa_pcm: xrun of at least 27.009 msecs load = 0.1419 max usecs: 49.000, spare = 23170.000 load = 0.1205 max usecs: 23.000, spare = 23196.000 load = 0.1012 max usecs: 19.000, spare = 23200.000 load = 0.1001 max usecs: 23.000, spare = 23196.000 load = 0.0845 max usecs: 16.000, spare = 23203.000 load = 0.0767 max usecs: 16.000, spare = 23203.000 load = 0.0642 max usecs: 12.000, spare = 23207.000 load = 0.0773 max usecs: 21.000, spare = 23198.000 load = 0.0882 max usecs: 23.000, spare = 23196.000 load = 0.0807 max usecs: 17.000, spare = 23202.000 load = 0.0727 max usecs: 15.000, spare = 23204.000 load = 0.0729 max usecs: 17.000, spare = 23202.000 load = 0.0752 max usecs: 18.000, spare = 23201.000 load = 0.0850 max usecs: 22.000, spare = 23197.000 **** alsa_pcm: xrun of at least 9.031 msecs load = 0.1308 max usecs: 41.000, spare = 23178.000 load = 0.0998 max usecs: 16.000, spare = 23203.000 load = 0.0758 max usecs: 12.000, spare = 23207.000 load = 0.0745 max usecs: 17.000, spare = 23202.000 jack main caught signal 2 stopping driver detaching driver unloading driver So, nothing is working neither muse, nor rosegarden or ardour or .....anything else Last thing when I perform lsmod, iget this : Module Size Used by Not tainted ide-cd 34148 0 (autoclean) lp 8288 0 parport_pc 25768 1 parport 35560 1 [lp parport_pc] snd-seq-oss 32800 0 (unused) snd-seq-midi-event 6336 0 [snd-seq-oss] snd-seq 45104 2 [snd-seq-oss snd-seq-midi-event] snd-pcm-oss 43780 0 snd-mixer-oss 14224 0 [snd-pcm-oss] snd-intel8x0 23112 0 snd-pcm 81700 0 [snd-pcm-oss snd-intel8x0] snd-timer 20068 0 [snd-seq snd-pcm] snd-ac97-codec 47064 0 [snd-intel8x0] gameport 3284 0 [snd-intel8x0] snd-page-alloc 9044 0 [snd-intel8x0 snd-pcm] snd-mpu401-uart 5024 0 [snd-intel8x0] snd-rawmidi 18688 0 [snd-mpu401-uart] snd-seq-device 5832 0 [snd-seq-oss snd-seq snd-rawmidi] snd 45668 0 [snd-seq-oss snd-seq-midi-event snd-seq snd-pcm-oss snd-mixer-oss snd-intel8x0 snd-pcm snd-timer snd-ac97-codec snd-mpu401-uart snd-rawmidi snd-seq-device] soundcore 6564 0 [snd] Well if someone have any idea, it would be nice to get this working ; I really need to make music with linux, I don't want to be obliged to run my atari falcon with cubase audio until the end of time !!!

[linux-audio-user] /dev/midi... which one?

by Tim Sullivan

Hello, I have a couple of related questions I am hoping some kind soul on this list might clarify. I'm currently running Fedora Core 1 with the CCRMA kernel 2.4.24 + CCRMA alsa RPMs. I'd like to write a small test program to send/receive to a midi device connected to: 1) midi port on sound card, 2) midi port on USB MidiSport 2x2. The output of aconnect -lio shows client 0: 'System' [type=kernel] 0 'Timer ' 1 'Announce ' client 64: 'Rawmidi 0 - ES1371' [type=kernel] 0 'ES1371 ' client 72: 'Rawmidi 1 - MidiSport 2x2' [type=kernel] 0 'MidiSport 2x2 Port 0' 1 'MidiSport 2x2 Port 1' When looking in the /dev directory, I see different flavors of midi devices (eg /dev/amidi0, /dev/dmmidi0, /dev/midi0, /dev/rmidi0, /dev/snd/midiC0D0, etc.) My test program needs to open a connection to the appropriate devices. So, my questions are, what device does alsa map to the sound card midi port and what device would I use for the USB connected MidiSport? Thanks in advance for your help. -tim

[linux-audio-user] Start up script for DAW ...

by Russell Hanaghan

Was wondering if it is possible to write a relatively simple startup script to start Jackd, AlsaModular synth with my specific file/patch (AMS will start Jack on its own too) then patch capture 1 & 2 to AMS then AMS to PCM's out, and then "wire" my midisport 2x2 port "A" to AMS midi in? It would be nice to boot at the gig, click on an icon and have everything come up. Also, I run everything 'su root' in a console too. thanks P.S. Running Mandrake 9.2

Your milage will vary ;) It depends on the positions of the monitors, how loud they are, how loud the sound sources are, and how picky the musicians are. It's just that it's much harder to get away with delay in the monitors than it is in the mains. If you can make it work, more power to you! I wish you well in your endeavor!
