I have found another post about someone mentionning KMS, issue with USB soundcards on recent Kernel and Radeon graphic card. I wonder if these 3 things might be related?

I read this bug description by Intel, and the sentence that decided me to buy a USB2 soundcard is this: "High-Speed and Low-Speed USB devices are not impacted by this issue." I actually have an Edirol UA-25Ex that plainly doeson't work on these USB ports, so I went for the M-Audio USB2 High-Speed hoping that would solve the problem!

linuxsampler with jack2 (was Re: linuxsampler on 64 bit Ubuntu)

Cracking sound via USB (ALSA urb.c:480: frame 5 active: -18)

by Aurélien Leblond

Hi, I seem to have an issue with USB soundcards on my laptop. I have tried two of them, but I keep getting crackling sounds while playing with Ardour or Hydrogen. Everytime this crackling sounds occur, I get the following in dmesg: ALSA urb.c:480: frame 5 active: -18 The Kernel is 2.6.39 with Irqthreads, Alsa is the git version (1.0.24). The usb-snd-audio module is loaded with nrpacks=1 Jack settings are realtime, frames/period=256, SampleRate=48000, Periods Buffer=3. The USB Controller is the dreaded EHCI USB Controller: Intel Corporation 5 Series/3400 Series Chipset USB2 Enhanced Host Controller (rev 05) But the soundcard I'm usins is USB2, not USB 1. I have tried a lot of things already, but I'm really ready to restart the investigation from scratch and to provide any information! Thanks in advance for the help. dmesg details: [ 41.927872] CE: hpet2 increased min_delta_ns to 7500 nsec [ 41.927897] CE: hpet2 increased min_delta_ns to 11250 nsec [ 75.569991] CE: hpet5 increased

Re: [LAU] Recommended USB interface with 2 XLR inputs?

by Aurélien Leblond

Hi everyone, You have the M-Audio Fast Track Ultra. I'm testing one currently and it "works almost" out of the box in Ubuntu 11.04 (kernel 2.6.38) but: - Alsa needs to be modified to get the Midi recognized. The fix is already known and I'm very confident it will get to Alsa mainstream soon. - The internal routing of the soundcard is done via software. There is a patch available wit the basic functionality but I haven't tested that yet. Oh and the main developers of this functionality has been posting stuff today on the Alsa-Devel mailing list, so he's working on it. - There is a small bug where the sounds cards is dropping samples. Daniel Mack from the Alsa-Devel is working on it. The most complete thread on the subject is here: http://forums.m-audio.com/showthread.php?714-Not-a-problem.-FastTrack-on-li… Overall, it's not as well supported as the Edirol UA-25Ex for example (the USB one I used to have), but I'm very confident it's only a questions of months.

LAC: A musician's workflow slides?

Hi, Is there any recordings/slides/notes from Jeremy Jongepier's workshop "A musician's workflow: composing, recording and arranging with qtractor and friends" at LAC 2011? I'm very interested about his views, but couldn't find anything from the web, except this: http://linux.autostatic.com/2011/05/11/lac2011-het-perspectief-van-de-eindg… (By the way – big thanks to the LAC video crew!

Din Is Noise and AZERTY keyboards

by jy

Hi all, I'm having some trouble with din is noise : - i can't use the din console because after having pressed tab and entered a command, the return button is not recognised. - i'm using an AZERTY keyboard and thus the key mapping is totally different. I could switch to a QWERTY configuration but then this would change all shortcuts from the other software i'm using. is it possible to use different mappings ? Does anyone have any idea about how to solve these two problems ? thanks a lot

Streaming Radio

by Harry Van Haaren

Hey all, My local university are setting up an internet streaming radio station. They've a windows box with darkIce suggested as the machine to stream to a dedicated streaming server online. I'm thinking about suggesting doing a linux install, and providing support for the box if/when it breaks / wants a cigarette break :) So I'm aware darkice runs linux, and darkSnow is its GTK frontend. Nice for setting up! I'm wondering if there's something else that I'm missing? Also if there's suggestions out there for other software / stuff that might be of intrest, let me know! Cheers, -Harry
