[linux-audio-user] Recommendations for SPDIF/AESEBU

by Bill Adair

Hello all, I'm setting up a hi-end stereo system fed from flacs on a linux based PC. I want to be able to experiment with upsampling algorithms on the hard drive and then feed the digital data stream to a Lavry DA10 at 24/96. I'm currently running an M-Audio 2496 at 16/44.1 but am having bad problems with hesitations and popping and crackling (worst when running a DVB TV card at the same time (obviously)). The problems will get worse as I raise the bit rate. I'm looking for a route forward so has anyone got better suggestions than the following: 1) Get a Squeezebox - this will buffer the sound, play at 24/96 but lose PC audio e.g. the TV audio. 2) Get a better soundcard - I've read that the M-Audio 2496 is prone to the problem I'm having, but which one? RMEs are 200-300 UKP. Are any other alsa based cards suitable to deliver SPDIF/AESEBU at the higher bit rates? 3) Retune the PC, an Athlon 2700, by patching linux (Suse 10.1). I'm not current running jackd just alsa and flac123. Which patches are best applied to the 2.6 kernel? The FAQs seem a bit out of date being dated 2000-2002. Advice much appreciated Bill -- Using Opera's revolutionary e-mail client: http://www.opera.com/mail/

BUT: at least a 10 h trip, i cannot recommend it. http://www.mitfahrgelegenheit.de (pre-arranged lifts in private cars) is used a lot and usually works well. people charge ~25-30 eur for the trip.

[linux-audio-user] Music/Video: DJ-Mix with Freewheeling and Hydrogen

by Johannes Mario Ringheim

I've put together a new DJ-mix using one turntable together with Hydrogen and Freewheeling. My brand new BCF2000 is used for controlling the thing, and a sustainpedal triggers the looping. I've also videotaped it, so you can all see what I'm doing! Comments are as always appreciated. http://rasmus.uib.no/~jri022/ringheimsauto/loopmix.avi (Video) http://video.google.com/videoplay?docid=-2381754226424081568&q=loopheile (Google video) http://rasmus.uib.no/~jri022/ringheimsauto/Ringheims%20Auto%20-%20Loopmix.o… (Audio) http://rasmus.uib.no/~jri022/ringheimsauto/Ringheims%20Auto%20-%20Loopmix.m… (Audio) -- Ringheims Auto - Fri musikk for bilstereo! http://ringheimsauto.org

If I order them from Russia by mail, there is a 99.999% probability I will never see them :) Can I just order the tickets in Berlin, 5 days before the trip, for example and still get the discount? Sorry for stupid questions, but this ticket system is not that easy to understand. Dmitry.

[linux-audio-user] My new mouse done ate my alsa sound

by M P Smoak

Please forgive me but I've got say: Don't tell me my sys is old and OS version is ancient. It worked a few days ago to my satisfaction. I'm sick of hearing it. I'm running planet-ccrma rh9 on my machine Songbird for a long time now. I know it's old. Dave P. put together for me several years ago. And it's met my needs. I've tried (without success) to replace it with a new machine; never got sound to work, power supply fan sounds like a jet plane taking off; it'll work "some day". But Songbird kept working; reliable in spades. Last week, the mouse (acting odd for a long time) got too bad to use. So I take my friends advice and go to a usb mouse. Halt the machine; pull the ps2 mouse and plug in the use mouse. Boot; all seems to work well; all works except SOUND! Except my old standby, Realplayer. Alsaplayer doesn't play. Soundfont loads for my SBlive, alsa patch bay appears to work, QA mix looks as usual, .... We had no keyboard for our session tonight. With RH9, I think I know, Reaplayer forces use of OSS emulation from ALSA. It works; I'm sitting here listening to CJRT via Realplayer now. My keyboard is dead. USB is stepping on ALSA. I've searched, looked at all the logs I can find and damned it I have any idea what's happened or how to fix it if it's fixable. I'm searching for a working ps2 mouse too. I love linux, and computers, but they sure make saxophones seem simple. Marv real irritated in Lex, KY

[linux-audio-user] Livecoding in San Francisco?

by Ken Restivo

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Where could I find livecoding concerts and/or DJ sets here in San Francisco? I checked dorkbot.org and they don't seeem to have anything of that nature scheduled. Is that the right place to look? We're in close proximity here to CCRMA, Silicon Valley, Berkeley, Apple, and jwz's DNA Lounge... I'm amazed there aren't livecoding events every night here, but apparently not. - -ken -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (GNU/Linux) iD8DBQFF90zre8HF+6xeOIcRAhwSAJ96DMpOKt7PDBOiGhOGLURnaiAlJACggl3H z7p+Re5eGdQpO0jGf+tHRxI= =41dJ -----END PGP SIGNATURE-----

[linux-audio-user] browsing

by we are

two questions. are there any good programs out there that people use for browsing samples. i came across one call quickwav is handy but a bit limited. also. why is it that some applications use file browsers the order the files Alphabetically and others browse with all files uppercase alphabetically and then all lowercase alphabetically. in a saturated world of data and files i'm trying to find a quick way through it all. bit of a strange question but would be interesting to hear what developers perfer and why. thanks

[linux-audio-user] [RME HDSP 9632] No sound

by Bibulus

Hi all, I just bought a RME HDSP 9632 today but I cannot make it work. Yes, another guy with this same eternal problem... I already know that this card is (should be?) well supported under GNU/Linux (and in fact it is why I bought it)... My system/conf is: ----- * Distro: Debian/Sid * Kernel: vanilla 2.6.20.2 (+ realtime-lsm) with the following specific ALSA modules: RME Hammerfall DSP Audio RME Digi96, 96/8, 96/8 PRO RME Digi9652 (Hammerfall) What is the module I must use for a 9632? $ lsmod | grep hdsp snd_hdsp 43812 0 snd_rawmidi 18848 3 snd_seq_virmidi,snd_hdsp,snd_seq_midi snd_pcm 59908 3 snd_rme96,snd_hdsp,snd_pcm_oss snd_page_alloc 8328 2 snd_hdsp,snd_pcm snd_hwdep 7428 1 snd_hdsp snd 41828 12 snd_seq_virmidi,snd_rme96,snd_hdsp,snd_seq_oss,snd_seq,snd_rawmidi,snd_seq_device,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_timer,snd_hwdep $ lsmod | grep rme snd_rme96 20516 0 snd_pcm 59908 3 snd_rme96,snd_hdsp,snd_pcm_oss snd 41828 12 snd_seq_virmidi,snd_rme96,snd_hdsp,snd_seq_oss,snd_seq,snd_rawmidi,snd_seq_device,snd_pcm_oss,snd_mixer_oss,snd_pcm,snd_timer,snd_hwdep ----- I even try to use "hdsploader", but as far as I understand how it works, it is not required for the 9632: ----- $ hdsploader hdsploader - firmware loader for RME Hammerfall DSP cards Looking for HDSP + Multiface or Digiface cards : Card 0 : RME Hammerfall HDSP 9632 at 0xdcdd0000, irq 16 ----- Do you need more informations/screenshots about my system/conf? I have installed "alsa-tools" and "alsa-tools-gui" for "hdspmixer" and "hdspconf". "alsamixer" give me very poor information (but I have unmutted all I could unmutted with it). I have tried to use a ".asoundrc" file, but with no success. -> Notice that before RME I used to work with a Audigy2 and all was ok. But now the only little "sound" I can have is with jack (and only on playback_9 port, in the headphone left part). Any idea? Thanks for your help... Bye
