Audigy is not a bad card if you want hardware soundfont support (I'm unsure how good it is supported under linux though, last time I tried ,I've got one, it didn't work that well...) Having said this, I should add that I own several sb-live cards in various configurations. These days though I almost never use the built in support for soundfonts. Most of the time I find it better to use Fluidsynth. The only concern here is that Fluidsynth will consume CPU resources which the hardware synth won't. Regards, Robert

[linux-audio-user] Re: Audigy 6.1 platinum and Linux

by Juhana Sadeharju

Hello. Before anyone buys Creative's Platinum cards, I would like to tell how they most probably are not working. Multiple times I have tried to verify this with alsa-devel guys, but it looks like nobody else has tested. People only believes that their card is working but in reality it is not working as expected. If you disagree and have better info, please mail me and I will give you exact info how to test the card. I mean exact! We do not need anymore rumors and believes. Do not work in Alsa: -LiveDrive line-in 2 does not come out from the mix bus, but does come out via AC97 (whatever) path (perhaps low quality) -LiveDrive aux input does not work Has anyone tested the developer.creative.com drivers? How to test them with Alsa? I don't want install OSS. Can somebody test both Alsa and the d.c.c drivers? Best regards, Juhana

[linux-audio-user] supported soundcard

by nightrid3r

i'm looking for a sound card that comes with linux support. i recently switched over to linux and now i want to ditch my soundblaster card. I find it hard to locate any cards that work with linux. Could you give me some advice about a good card for linux. -- Network Administrator Services Root Administrater Botmaster For the chatfactory network Registered GNU/Linux user #305840

[linux-audio-user] USB Quattro and Jack questions

by Denis de Leeuw Duarte

Hi folks, I've got a few questions about the USB Quattro and Jack. Hope you can anwer s ome of them: I'm writing this app and I managed to get my Quattro going with Jack, but only two of the outputs are available as ports at a time (quattro1 or quattro2). Is there a way to invoke jackd so all four ins and outs are available as Jack ports? I use the .asoundrc file Patrik Shirkey wrote, but I understand too little of it to work it out :). Another question: How good/bad are the latencies other Quattro owners have experienced with Jack at 96k? Is it good enough to attempt close to real time signal processing in software? I've read somewhere that it is possible to bring latencies down to (quote) <0.5 milliseconds on a P500. Is this also possible with Jack? At 96k? I have an athlon-xp 1600 btw.

Hi, I'm wondering if anyone has written a RedHat-style init.d script for jackd. I haven't had any luck looking for one on the net. Thanks, Austin -- Austin Acton Hon.B.Sc.

[linux-audio-user] mi piacerebbe ALSA...

by stefano.cardo＠fastwebnet.it

Salve a tutti!! Lo so che è una lista in Inglese, ma dopo assurdi tentativi misono deciso a scrivervi... lo faccio in italiano perchè spero di poter fare dei passi avant più velocemente se trovassi un conterraneo disposto ad aiutarmi.. il mio problema è: Io uso una debian unstable e attualmente è installata una Creative Sound Blaster PCI128 (che credo abbia il chip ENS1371) Credo che siano installati gli OSS/Free (spero), tant'è che riesco a sentire i CD, suonare i midi, gli mp3 e gestire correttamente il mixer. Ho visto pero che i sound server e programmi tipo tapiir o ardour o jack si basano, o meglio funzionano molto bene con i driver alsa installati... ora, chi mi può aiutare ad installare i driver e a far funzionare sta benedetta scheda e i relativi programmi? ho letto che le alsa devono essere compilate nel kernel... devo scaricarmene uno e fare il lavoro a mano??? sinceramente spero di no, ma se fosse l'unica via, vi chiedo ancora più aiuto... Scusate e grazie in anticipo!! Stefano -- S t e f a n o C a r d o - windows? no, grazie... Debian GNU Linux User http://digilander.iol.it/goodman UIN #53379993

Re: [linux-audio-user] Audigy 6.1 platinum and Linux

by Robert Jonsson

Hi Ron, The thread started with an inquiry about which soundcards support Soundfont on their onboard synth chip, so it was perhaps not exactly what you thought it was. Though what you ask, syncing synths to software apps is probably involved :) The sb-live card (and it's siblings, ancestors and children) is in essence a low cost samplingsynth. By putting a bunch of these into a computer case I guess you could construct a fairly well working "external" synth. As for syncing, they would be controlled by midi, I'm not sure what you where aiming at here exactly, all synths do that don't they? Some of the cards have sp-dif, some of the newer even have firewire (or sb-firewire whatever that means (probably that it's broken)) so in theory they would have pretty good soundquality as well as sync possibilities...

[linux-audio-user] [PATCH] envy24control widget limits

by Ross Vandegrift

Hello, I wrote a patch this morning that lets the user define limits on the number of controls envy24control should display to the user. This is useful on cards like the Delta44, which only has 4x4 channels - it provides a cleaner interface in that case. The patch is included below, and is downloadable from: http://poplar.seitz.com/~ross/envy24control/envy24control-control-limit.diff The changes introduce two new command line options: -i, --inputs: Use this to define how many HW In channels you'd like -o, --outputs: Use this to define how many PCM Out channels you'd like So for my Delta44, I now use 'envy24control -i 4 -o 4' to only see the channels I physically have. That's about all there is to it. It seems to correctly handle limiting to fewer channels than physically present as well. Hopefully this can help out some others as well. I'm not subscribed to alsa-devel, so please CC me on any replies from that list. Thanks! -- Ross Vandegrift ross(a)willow.seitz.com A Pope has a Water Cannon. It is a Water Cannon.

[linux-audio-user] Making a demo.

by Marco Desiderati

Hi everybody. I'm an italian bass player and I'd like to record a 4 songs demo for the band I play in with my PC (with Linux obviously). I'm searching for someone who can suggest me any documentation/book regarding this argument and/or share with me his experience (the hardware/software used and so on ...). Thanks in advance for your reply, Marco.
