[linux-audio-user] ANNOUNCE: Rosegarden-4-0.9.6 released

by Chris Cannam

The Rosegarden team announce the release of Rosegarden-4 0.9.6, an audio and MIDI sequencer and score editor for Linux. To download the source package, go to the homepage at http://www.rosegardenmusic.com/ This release is primarily to address a significant problem with 0.9.5 that was seriously affecting sequencer timing performance for some users. For this reason we strongly recommend an upgrade. Be aware that one of the fixes in this release mandates the use of Qt 3.1 or newer to build; Qt 3.0 is no longer supported. This release also contains new translations of the GUI into Italian, Swedish and Estonian, thanks to Daniele Medri, Stefan Asserhäll, and Hasso Tepper. These are in addition to the existing support for US and UK English, Russian, Spanish, German, French, and Welsh. Chris

Re: [linux-audio-user] Recording from SPDIF with Audiophile

by Tommi Sakari Uimonen

Hi, try putting this to ~/.asoundrc pcm.spdif_capture { type plug ttable.0.8 1 ttable.1.9 1 slave.pcm { type hw card 0 device 0 } } ecasound -i alsa,spdif_capture -o alsa,plughw:0 (I assume that Audiophile is card number 0) or -o test.wav, but with the former you can monitor your spdif from the analog outputs (of course you can do the same with envy24control and setting the hw outs to spdif from the patchbay/router) If you don't know ecasound yet, try: arecord -D spdif_capture -f dat > test.wav Remember to set the clock input to spdif from envy24control->Hardware settings->Master clock->S/PDIF In, otherwise you get strange results or no sound at all. I have Audiophile 2496 and have successfully recorded through spdif, also together with analog inputs, but that needs more .asoundrc magic: pcm.2496_test { type plug ttable.0.0 1 ttable.1.1 1 ttable.2.8 1 ttable.3.9 1 slave.pcm { type hw card 1 device 0 } } then: arecord -D 2496_test -c 4 -r 48000 -f S32_LE > test.wav gives you 4 channels.

[linux-audio-user] alsa rtc patch in 2.4.23?

by James Stone

I was wondering if anyone has patched the kernel with the rtc patch for alsa in 2.4.23? I have patched it on 2.4.20 but was wanting to upgrade the kernel and 2.6.0 seems a little unsupported audio-wise at the moment. Any success stories and howtos would be appreciated. James

[linux-audio-user] Kernels, and disk I/O

by Anahata

Hi While all the excited chat is about the shiny new kernel 2.6.0, I have a 2.4.x question: I used 2.4.18 until recently, when I found that a disk I/O scheduling problem (lack of responsiveness while writing backups to an optical disk) was solved by upgrading to 2.4.20. Now I find that recording audio on 2.4.20 is useless, with long droputs in the recorded sound. I'm sure this is related to the way the system periodically dozes off for a few seconds (not echoing console input) while it does some disk intensive work. Rebooting 2.4.18 restored audio sanity, fortunately. The kernel has no low-latency patches applied. The sound system is M-Audio DIO2448 + OSS drivers Hard disk is standard IDE, tuned with hdparm Distro is Debian 3.0 with quite a lot of "testing" packages installed. Base H/W 800MHz Duron + 256M RAM. This does seem to be related to the disk I/O scheduling change, or possibly virtual memory Is there a kernel guru who can advise? Possible options seem to be: 1. Apply low latency patches 2. Upgrade to 2.4.22 3. Upgrade to 2.6.0 4. something else? -- Anahata anahata(a)treewind.co.uk Tel: 01638 720444 http://www.treewind.co.uk Mob: 07976 263827

Are you sure it's not a problem with the card itself? Have you tested it with a different box, maybe on a Windows or on a ccrma Redhat system? M

[linux-audio-user] Recommendations for audio software needed

by Conrad Newton

I need some advice from those more experienced with audio software than myself. I am building a Knoppix-style live CD that will be used by teachers and pupils in Oslo, Norway. Most of the users are unfamiliar with Linux, and the CD is supposed to be their first introduction. Within the audio category, it is obvious that I should have a CD player (kscd), a CD-burner (k3b), and an mp3/ogg player (xmms). I also want to have some music editing software, and I have identified the following programs as potentially interesting ardour audacity muse rosegarden4 I have also been meaning to include solfege, the ear training program on the CD, but without really being certain how many people would use it. My question is, if I can only include 2 of the above programs (for space reasons), which two should I take? Bear in mind the restriction that the users are not a high-tech crowd. If I can make an analogy with image manipulation, let me say how I solved the problem: I included both tuxpaint, a simple paint program that even small children could enjoy, and the GIMP, an advanced image manipulation program that counts in some circles as an Adobe Photoshop replacement. In this way, both the beginner and the advanced user can be satisfied. I would like to satisfy the audio users in much the same way, if I could. Thanks in advance for your comments and advice.

[linux-audio-user] Re:M-audio products

by David Baron

I have a Dman2044. Oldy but goody with a nice chunky breakout box. 4 by 4. Alsa list this for a cs46xx driver. Knoppix install detects it as an AGOPO Maestro card Alsa's auto install detects it as an es1968, also Maestro. None of these alternatives work. The OSS Maestro driver will load but not play. The alsa's will kick at the modprobe Any one know what to do? (I have posted on this before.)
