[linux-audio-user] Interuptions While Recording

by linuxmedia4＠netscape.net

Greetings, I was having interruptions when recording with ecasound. Someone at the ecasound list suggested that it was because my Hard Drive was slow. I upgraded from a 5400 RPM Drive to a 7200 RPM Drive and it did help. The inturuptions are less often and shorter. They're usually just an occasional click, and at times can be about a half a second of silence (while recording). When I listen to the recording, at the spots where the interuptions happen, the parts are edited out. In other words, there is __no__ silence (in the file) where the interuptions happen, but it's as if someone just cut those parts out of the recording and pasted the remaining file together. I found several tutorials on hdparm on the internet. I used it to check my Hard Drive's capabilities and carefully made adjustments accordingly. Nothing worked. In fact most of the time the -Tt flag showed that the Timing buffered disk reads went down considerably. And, of course the interuptions kept happening. Here is the output of hdparm -Tt /dev/hda: Timing buffer-cache reads: 128 MB in 0.97 seconds =131.96 MB/sec Timing buffered disk reads: 64 MB in 1.35 seconds = 47.41 MB/sec Is this considered slow (when it comes to doing 16 bit 2 channel 44100 Multitrack Recording)? I did the command "dsmeg" and found the line: "SiS730 ATA 100 controller" And the Mother Board Manual says: "The PCI IDE also supports PIO Mode 3 and 4, UDMA33/66/100 IDE" Does this means it only capable of 100 MB/sec Data Transfer Rate? And does this even have much of a bearing on the interuptions I'm having? I installed an ATA/133 PCI Adapter Card and did the command hdparm -Tt /dev/hda and got the following output: Timing buffer-cache reads: 128 MB in 0.95 seconds =134.74 MB/sec Timing buffered disk reads: 64 MB in 2.19 seconds = 29.22 MB/sec I'm not sure why it produced lower numbers. This could be a configuration problem. But I'm not even sure if the card is nessesary. My Software/Hardware: SuSE 8.1 k7SEM Mother Board AMD Duron 1Ghz Processor 256 Megs Ram Soundblaster Live! 5.1 alsa Version 0.9.0.cvs20020903-13 (That's the Alsa that installed with SuSE 8.1 - It hasn't been altered in any way) Anyone have a clue how to stop these interuptions? Any help would be appreciated Rocco __________________________________________________________________ The NEW Netscape 7.0 browser is now available.

[linux-audio-user] Linux multimedia distributions

by Ismael Valladolid Torres

Hi, I am interested in current Linux distributions oriented to multimedia and more specifically audio (professionally or hobbyist oriented). I have located this ones: Demudi - http://www.demudi.org/ Planet CCRMA - http://ccrma-www.stanford.edu/planetccrma/software/ I have heard about AGNULA and Rehmudi (a RedHat based Demudi, which in turn is based in Debian?) but I haven't been successful locating information about them. Information about these (and maybe others) audio oriented Linux distributions would be very useful for me. Cualquier información adicional sobre recursos en castellano relacionados con este tema, será también muy útil.

[linux-audio-user] problems sending sound files directly to /dev/dsp

by Gustavo Zamorano S.

I have a PC with a P4 Intel chip at 1.8GB. My mainboard has a VIA8233 chip. It is running on Red Hat 8.0. The ALSA drivers ( snd-via82xx) seem to be working fine with play or aplay. My modules.conf lines added by alsaconf are: # --- BEGIN: Generated by ALSACONF, do not edit. --- # --- ALSACONF verion 0.9.0 --- alias char-major-116 snd alias snd-card-0 snd-via82xx alias char-major-14 soundcore alias sound-slot-0 snd-card-0 alias sound-service-0-0 snd-mixer-oss alias sound-service-0-1 snd-seq-oss alias sound-service-0-3 snd-pcm-oss alias sound-service-0-8 snd-seq-oss alias sound-service-0-12 snd-pcm-oss options snd major=116 cards_limit=1 device_mode=0666 options snd-via82xx index=0 # --- END: Generated by ALSACONF, do not edit. --- I have two problems: 1) If artsd is running, play or aplay will not be able to play a sound file until I kill artsd. I had to configure KDE not to run artsd. That means that if artsd is running, there is no sound. How can I have artsd running without disabling sound output? 2) As I discovered the function of artsd is to allow some programs to write directly to /dev/dsp. The problem I have is that when some program writes directly to /dev/dsp (while artsd is not running) I only hear a cracking noise. How I can have programs to write directly to /dev/dsp?.

[linux-audio-user] Hammerfall HDSP 9652 ?

by Oyvind Hammer

Hello all, we have purchased a Hammerfall HDSP 9652 soundcard with 3x ADAT out (no converters). We can not get it to work with either the ALSA driver for Hammerfall RME 9652 or for Hammerfall HDSP (modprobe fails, sometimes with a segfault, even if it is run very early in the boot process). I must say we are entirely confused about the different names of these cards, and what driver (if any) is supposed to work with our card. Has any on this group managed to get the Hammerfall HDSP 9652 with 3x ADAT out (no converters) to work under ALSA (or OSS?). If so, any advice? Thanks! Oyvind Hammer & Natasha Barrett Oslo, Norway

[linux-audio-user] Mandrake Audio Update

by Austin Acton

Hey, I just wanted to thank you all again for the great response I got to my totally uncalled-for survey. The volunteers and the staff at Mandrake have taken your requests to heart! We have a small task force packaging all the rpms you've requested. Most are done, and hopefully the rest will be finished by 9.1 release time (two months away). I gotta say, ardour took me two DAYS to package in an easy-to-use form, but I think it's pretty good. We've added a lot of alsa and jack utils that weren't there before, some you hadn't even asked for. Also, we've prepared a multimedia kernel with pre-emptable, low-latency, capabilities, and o_stream patches. It may be hard to get the company to include this in the 'main' distro, but it will definitely be in the contributor's section (that's where most of the audio software is anyway). As well, the installer team (Pixel) has added full USB audio detection, and a graphical setup tool for soundcards and sound system (OSS/alsa) to the installer. It's a bit unpolished as of today, but we've got two months to perfect it. Beta 3 was a bit rocky, but if any of you have a spare machine or a spare partition, I'd invite you to try beta 4 when it's released (two weeks maybe?). Should be a multimedia masterpiece. :-) Again, thanks for your help. It really counts. Let me know if you have any more questions or requests. Austin -- Austin Acton Hon.B.Sc.

Re: [linux-audio-user] Just how bad is USB audio?

by Frank Barknecht

Hi, I've got my first laptop, yeah. Problem is the sound. The internal Intel-chip works, but that's about it, it sounds horrible. So I think I'll need a USB soundcard or maybe PCMCIA? But I don't want to spend too much (i.e. no RME) So what could you recommend in the range 100-200 EUR? I would prefer something with Midi, but I could go without. I need stereo in and out, though. Any ideas? Do the Audiotrak MAYA USB boxes work (well) with Linux? ciao -- Frank Barknecht

As a long time Debian user I sometimes use the >Demudi distribution as a kind of Planet-collection for sound packages that >haven't found their way into debian yet. If you are looking for a completly new distribution, I have to tell you that I have been very pleased with SuSE 8.1. It seems to have a good variety of Music/Sound apps and always delivers what it says it will. My sound card configured without a hitch (Soundblaster Live! 5.1). Except for the program "Muse", I can't think of any other Music/Sound programs that didn't work they way they were supposed to.

[linux-audio-user] Planet CCRMA

by Jlawrence＠tacenergy.com

I've just downloaded the planet ccrma materials and I will be installing them over the weekend. I'm curious about the applications contained in the package: 1. Is there a way to just install everything in one swoop, or do I have to rpm -Uvh xxx.rpm every time on all packages? 2. What about packages (movie and sound players come to mind) that already exist in some form in a standard RH 8.0 install? Will installing over them confuse the situation? 3. I'm doing this on a Dell Laptop. Am I doomed to failure? Thanks, Josh Lawrence

Re: [linux-audio-user] ALSAModularSynth

by manuel.op.de.coul＠eon-benelux.com

Good, looking forward to it. >BTW I have a vintage digital piano at home (Yamaha PF2000) which >offers a lot of different Scales. I have not seen this interesting >feature in any other digital piano since then. You could try to retune it with Scala via MIDI. I suspect it supports XG sysex data, so you can do SET SYNTH 108. Otherwise I could add support in Scala if you send me the sysex codes for tuning. Manuel
