Re: [linux-audio-user] Re: My Edirol UA-20 arrived, but now I have a big problem!

It's safest to plug the equipment all into the same circuit.

[linux-audio-user] CHANGES to pan.zipcon.net

by al goldstein

Changes at http://pan.zipcon.net 1) header info now on all files 2) 7 recordings are added: 4 flute, 1 piano, 1 duo-piano and 1 bassoon 3) TO DO: record jacket info Thanks for the many comments and criticisms. They are needed. The quality of the added recordings varies. We think the 2-piano recording is a demo recording for ogg; some of the others are of marginal quality. However there are those who will want them. Download at any time. However downloading from 1PM to 1AM PST may be subject to interruption. Of late there have been more mp3 users than ogg.

[linux-audio-user] My Edirol UA-20 arrived, but now I have a big problem!

by Frank Barknecht

Hallo, my Edirol UA-20 USB audio device has arrived, and I also got it to work: It was almost plug and play. But now I have a serious problem, and that is noise when moving the mouse. I'm at loss what to do. Everytime I move the pointer with mouse or touchpad on my Acer Travelmade, the UA-20 produces nasty screetching, crackling and scratching. This doesn't happen, when I unplug the power supply. The UA-20 gets its power from the USB-port, so I suspect that this creates the conflicts. Does anyone have an idea how to get rid of this noise? Or should I send back the USB device? Thanks for any help... ciao -- Frank Barknecht _ ______footils.org__

[linux-audio-user] alsa - unresolved symbols

Hi, I am using Debian Linux 3.0 (Woody) with 2.4.20-Kernel!

[linux-audio-user] ardour cvs problems

by Linux Rob

Hey, I'm diving into cvs for the first time, so please excuse my ignorance. I'm trying to compile ardour, but after running autogen.sh, I get an error saying that I don't have autopoint correctly installed. I tried apt-getting autopoint, but it doesn't seem to exist. I googled for it, and came up with nil. The only reference to it is that it has some connection with gettext. However, gettext is correctly installed (I even uninstalled it and reinstalled) yet I still come up empty handed. Does anyone have a clue of why this is happening or where I can get a hold of autopoint? Thanks in advance, Linux Rob

[linux-audio-user] low-latency/preemptive kernel 2.5+ (rpm?) anyone?

by kevin ernste

Hello - I am experiencing xruns and audio glitches on a new machine running PlanetCCRMA/Redhat8 with an RME hammerfall card and have recently discovered the problem: the motherboard chipset is unsupported by kernel 2.4.x and needs kernel greater than 2.5.12 fort DMA I/O can be enabled. Does anyone on this list have an audio ready (low-lat/preemtive enabled) kernel rpm greater than 2.5.12? Kevin ===== "A tax cut? With war looming and a projected federal budget deficit?

[linux-audio-user] [ANN] JACK Rack 1.4.1

by Bob Ham

Hi all, Some fixes and extra bits for the midi stuff; makes things much more responsive. * icon and .desktop get installed properly * much more graceful handling of jackd shutdowns * midi thread will now try and use SCHED_FIFO. If you run jackd with jackstart (or as root, but you don't want to do that :) then you don't need to do anything to enable this as jackd will give the appropriate rights to jack rack.

[linux-audio-user] Re: [Audacity-users] Multi-input sound cards

by Daniel James

> I'm very patient and would eagerly help you test the multi-channel > recording abilities. I'm not always patient but I could help there too. If Dominic has a USB Quattro already, maybe we should do a quick survey of what other devices are available/needed for testing. I was thinking of getting a PCI MAudio card for this. I'm cross-posting to the Linux Audio User list, because I'm sure there are some people on there who would like to give Audacity with multi-channel input a go. Cheers Daniel
