The reason I announce this release of Scala, a program to explore musical tunings, is that the Linux version finally works with MIDI now. It uses the OSS devices, but I have only tested it with ALSA. If you want to use an ALSA softsynth, you can connect it via a virtual MIDI device. http://www.xs4all.nl/~huygensf/software/scala-20-pc-linux.tar.bz2 Scala is also very useful as a virtual keyboard, one that can be used with any tuning. After setting the device with Edit->Sound Settings, press F4, select a notation system, click "Scale preset" and play. There are several dialogs that can play, most in the Analyse menu. You might like to try the Tonality diamond, Triad player, Tone circle, etc. The View->List of Chords dialog can play any predefined chord. Any volunteers for porting Scala to OS X on this list? I hope ALSA will support the MIDI Tuning Standard for soundcard synthesizers sometime. Then we can have much better accuracy. Manuel

[linux-audio-user] Capture with DIGI9636 Hammerfall Light and playback with PCI 128

by Martin Buechler

Hi, I am able to record using alsa/jackd/ardour with the analog input from an AEB/4-I and plain pcm.rme9652 after tweaking /etc/asound.state by hand for getting the internal input from the AEB working. jackd/ardour works also very well with the PCI 128 only, even at period size 64. Now, I want to record with the RME and having analog playback through the PCI 128. Is this possible? If yes, how to setup .asoundrc? I have been trying many combinations of multi and ttable settings, but honestly, I do not fully understand the syntax and semantics of alsa configurations. I am using kernel and alsa-0.9.0 from a recent PlanetCCRMA distribution, which is really a piece of gold. BTW, after fumbling around with my own kernel patching, I ended always with a complete freeze of ardour, when running jackd in realtime mode. Here is, what aplay says: [root@ardour root]# aplay -l card 0: AudioPCI [Ensoniq AudioPCI], device 0: ES1371/1 [ES1371 DAC2/ADC] Subdevices: 1/1 Subdevice #0: subdevice #0 card 0: AudioPCI [Ensoniq AudioPCI], device 1: ES1371/2 [ES1371 DAC1] Subdevices: 1/1 Subdevice #0: subdevice #0 card 1: 15 [RME Digi9636 (Rev 1.5)], device 0: RME Digi9636 (Rev 1.5) [RME Digi9636 (Rev 1.5)] Subdevices: 1/1 Subdevice #0: subdevice #0 [root@ardour root]# aplay -v -D hw:1,0 /usr/share/tuxracer/sounds/tux_on_rock1.wav Playing WAVE '/usr/share/tuxracer/sounds/tux_on_rock1.wav' : Signed 16 bit Little Endian, Rate 44100 Hz, Stereo aplay: set_params:789: Access type not available Pretty strange, since ardour does not complain, when trying to playback with the RME. Someone stated, that ardour ist writing directly to the hardware, and seems to have no problem, when there's nothing connected to the cards digital outputs. I also don't dare trying to understand, why there is one capture/playback device in /proc/card1/dev for the RME, while ardour reports 18. Since I do not want to purchase another AEB/4-O analog output box, I would really like to know, how I could use my cheapo SoundBlaster. Thanks for your help Martin

[linux-audio-user] xruns vs. disk activity

by rob fell

Hello all I'm trying to get a gentoo based audio box (primarily Ardour) off the ground. Despite my best efforts, I can't eliminate xruns to a level I could live with (10ms+ xruns every 2 minutes on average seems excessive - esp. with stereo @ 44k1). There's some captured data at the very end of this mail. My observations are made using; jackd -v -R -d... -r 44100 -p 128 2>&1 | tee jacklog (i.e. stereo SB16 @44k1) and ardour, session open but not actively playing I'll present my questions before wandering off into a tedious list (apologies for length) of stuff I've already done. Would anyone care to offer an opinion on these questions; 1. Am I expecting too much? Either from my hardware, or the current state of Linux. 2. Is there a vital piece of config that I've totally overlooked? 3. Is there a better way to measure this to home in on the source of the problem? 4. Are the xruns incidental to the disk activity - is this all a symptom of something else? 5. Insert any other question I should be asking here. Thanks in advance for any help/advice offered, I've run out of ideas. Ta R The (abridged) story so far...

[linux-audio-user] mplayer audio-out weirdness

by Dave Phillips

Greetings: Recently I added a DVD drive to my system. My aging RH 7.2 recognized the drive with no trouble, and after I linked /dev/cdrom1 to /dev/dvd MPlayer handled a DVD with not much trouble. Video performance was sluggish though, and worse, I had no audio. So I dug into the MPlayer docs (they're good!) and discovered lots about improving the video performance, but I still couldn't get a peep out of the movies. The drive's analog audio output is connected to the second card (a PCI128) in my machine, yet no matter what I did with the mixer I got no sound. The card output was routed out to a Bose sound system. Here's where the weirdness starts: While fiddling around with things I discovered that I did in fact have audio. It's coming out of my SBLive, not my PCI128 ! Now how does that happen ?? The drive is physically connected to the PCI128, *not* the SBLive, yet the audio is indeed coming from the SBLive. Can someone explain how this is possible ? Do the cards share a codec, and does that matter ? Is DVD audio handled differently than CD audio ? I'm very happy with my new drive and with MPlayer, and I'm glad to have good sound, but what the hey ?! Btw, MPlayer rocks, even under my "adverse" conditions, i.e., I compiled it with GCC 2.96 and am using an nVidia GForce2 video card. Ha, it all works great !

[linux-audio-user] Buzz works with wine!!!

by Emiliano Grilli

Hi linux-audio-users subscribers, Today I have succesfully used buzz with the latest version of wine. If you don't know it, buzz (www.buzzxp.com) is a very well thought combination of a tracker plus a modular synth, and it's freeware (but I think there are only binaries for windows). It has also a good community behind and a lot of machines/modules/patches available. It appears to work well and sounds very good... under wine (latest version on RedHat 8.0 + PlanetCCRMA) Just FYI, I don't remember discussing buzz on this list and you can also tell me that's a bit OT, but you know... I can't resist ;-) (sorry 4 my english) Bye -- .-----------------------. | Emiliano Grilli | | emillo(a)libero.it | | Linux user #209089 | | http://www.emillo.net | '-----------------------'

[linux-audio-user] Gstreamer-Properties and ALSA/JACK

by Alex Combas

Hi folks, Im an audio newbies running gentoo-1.4 Im using the alsa drivers for my SBLive5.1 card and when I run gstreamer-properties (version gstreamer-0.6.1-r1) the only setting that will produce sound output is OSS ..its kind of irritating to know that all of my gnome apps that use gstreamer are feeding the sound to OSS instead of alsa or jack both of which are in the menulist of options for gstreamer-properties. So basically I was wondering if I am suppost to do something special to make gstreamer work with AlSA or JACK.. obviousely there must be some sort of gotcha somewhere that Im not aware of. Thanks. Any {help|info|guidance} would be greatly appreciated. -- Alex Combas <ghetto_samurai(a)shaw.ca> This message is digitally signed.

[linux-audio-user] No CD audio!

by Tim

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, My CD will not pass the audio of CDs to the onboard sound. If I use XMMS and the libcdaudio plugin, the disc is seen and played but no sound comes through (Geforce nForce audio which is run with Intel ICH kernel configuration). CDtool also is unable to play audio CDs, with the error cdplay: ioctl cdrommsf even as root, so not a permissions problem. cdir and cdeject work. It works just fine using SCSI emulation, I can mound data CDs, write CD-Rs, rip audio CDs. My onboard sound works otherwise, successfully playing from the hard disk. I have had the CD drive replaced already for another reason, but the problem remains. There is no play button on the fascia of the drive, or headphone socket.
