The Mother Board Manual states: "The K7SEM is installed with the economical high-performance SiS730S chipset..." Of course, it goes on with other specs, but I thought this would answer the question about if it was SiS. Just as a double-check (because the salesman told me that the manual refers to several different mother boards) I looked (in KDE) under "Information" ---> "PCI" and it says: "00.00.1 IDE Interface: Silicon Integrated Systems [SiS] 5513 IDE..." I appoligize for my lack of savy. Does this answer the VIA/SiS question? If so, do you have any other ideas of where I may need to investigate next? According to the article, I have the _exact_ Ultra ATA/133 PCI Adapter Card _and_ Hard Drive to acheive the highest speeds. The _Hard Drive's_ specs say: Buffer size: 8 MB Average seek time 9.1 MS DATA Transfer rate: 133 MBytes / sec (Ultra ATA/133) Rotational Speed: 7200 RPM So with the ATA/133 Card, the Hard Drive and (following) Hardware/Software specs, shouldn't this be enough to allow flawless multitrack recording: 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) If you remember, when I installed the card and then did: "hdparm -Tt /dev/dsp" the Timing buffered disk reads MB/sec were lower than before I installed it. So, if you think the card is a worth fooling with, do you have any idea why the Timing buffered disk reads were lower (and how to bring them up)?

[linux-audio-user] JACK 0.50 released

by Taybin Rutkin

Jack Audio Connection Kit 0.50.0 Released The Jack team is pleased to announce the release of version 0.50.0 of the Jack low-latency audio server. Jack allows applications to share data and audio devices in synchronous operation, and has already seen a year of hard testing and refinement. The API has stabilized for the foreseeable future, although backwards compatibility is not guaranteed. More information on Jack is available at the group's web site, [1]http://jackit.sourceforge.net/. Source packages for Jack 0.50.0 are available [2]here. What's new: * Audio block sizes are fixed during runtime so clients can have more efficient algorithms. * No partial blocks will be delivered. Again for efficient client algorithms. * Thread scheduling hidden from clients for better portability. * Cleanly compiles with gcc-3.3. * Works on 64-bit platforms Work is ongoing to improve transport control. Developers and users interested in Jack should sign up to [4]jackit-devel, our mailing list.

[linux-audio-user] [ANN] ALSA Patch Bay 0.5.0

by Bob Ham

Hi all, Now supports jack. It needs the patchbay-facilitating jack functions that are only in cvs atm, tho; there's been no tarball release with them yet. And yes, it's still called "ALSA" patchbay :) * added jack driver, also installing a jack-patch-bay link to alsa-patch-bay and a jack-patch-bay.desktop * added client subscriptions, similar to qjackconnect; press a read port twice http://pkl.net/~node/alsa-patch-bay.html Bob -- Bob Ham <rah(a)bash.sh>

[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
