I've never used a 64bit system on linux. Mixing has never worked properly with alsa, and thats the main cause of, at least my, frustration. However, what triggered the above message was actually that my new office machine has a graphics card with a hdmi sound card. The amount of work (paid by my employee) required to force the computer not to use that sound card as the default was what made me want to explore OSS instead of ALSA. Alsa is nice in various ways, but it's just too complicated.

Flash problem

by Folderol

I've finally got around to thinking about upgrading my website, so thought it would be a good idea to have an embedded player as well as the download options. Well it seems that the only more-or-less universal players are all flash players. Not wonderful but I guess I can live with it. There were three that looked quite reasonable and easy to configure, and the all seem to work well enough, baring one problem. None of them has a transparent background - although the all claim to have the option :( I've tried all the various suggestions on different sites, but steadfastly get a white background. I'm only able to try this out with firefox at them moment, so I don't know if that's behaving strangely. Anyone else come across this problem and found a way round it, or, better still, anyone know of another plugin that will work on the majority of browsers? -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune.

Re: [LAU] Am I experiencing ground hum or is it something else?

by Andrew C

Just out of interest Will, I've already tried 2 separate power supply plugs into my keyboard, and I still get an annoying noise when plugging them into an amp/line in on my PC soundcard. The keyboard has onboard speakers, but I can't detect any annoying noise when the keyboard volume is up full, with my ear against the speaker... This might be a problem with my sockets and/or my keyboard line outs being futzed? Thanks, Andrew.

Linux netlabel?

by Ken Restivo

So much good stuff coming out these days on the LAU list; I have to wonder if anyone's looked into starting a Linux-based netlabel? i.e. artists who are working with Linux specifically. There might be enough critical mass at this point-- or soon-- to make such a venture viable. -ken

musical audio analysis?

by Greg

Hi all, I saw a program a year or two ago that would display spectral data very prettily and also give note names. I hate that I'm having trouble describing it accurately, I just remember it as a "very musical spectrogram program" ... argh... does anybody know what I'm talking about?

Re: [LAU] Seu artigo na revista "Espírito Livre"

by Leandro Leal Parente

E aew Paulo, tudo bem ? >Já uso o Ubuntu Studio há algum tempo em casa (Ardour, sobre um jack server) e gostaria de trocar idéias. que bom que você trabalha com o Ubuntu Studio, é difícil encontrar pessoas que trabalham com áudio em Linux. Podemos sim trocar algumas idéias e sem dúvida irei aprender muito com você. >Que placas de som possuem a melhor compatibilidade com Linux? Entre as profissionais e as amadoras? Eu trabalho com uma controladora MIDI BCD3000 que tem uma interface USB, por isso possui uma alta latência. Não conheço muitas placas de áudio pra te informar qual tem melhor compatibilidade com Linux. Para conseguir essa informação posso ti dar duas dicas: - Te uma olhada aqui (se vc não já tiver olhado): http://www.alsa-project.org/main/index.php/Matrix:Main - Acompanhe os emails da lista Linux-audio-user( linux-audio-user(a)lists.linuxaudio.org), eles sempre comentam sobre a placas que eles utilizam (amadoras e profissionais). Você utliza o UbuntuStudio para qual finalidade ? Produção ? Mixagem ? Edição ? Eu basicamente utilizo o Linux para tocar como Dj e fazer algumas mixagens e poucas edições. Ja arrisquei produzir algum som, mas acho que preciso entender um pouco mais de teoria musical para começar a produzir algo legal. Obrigado, Leandro Leal

[OT] Chat programs for the graphic

by Julien Claassen

Hello all! Sorry for posting this here. But I suppose chatting and messenging is not such an uncommon task. So what would you recommend if I specified my plea like that; It should be able to understand e-mail, irc, icq and yahoo messenger. For mail it could be a different tool. But a mail tool should be able to export mails to .doc or something similar. And of course it should look nice. :-) If possible I should be able to export a lot of mails at one time. Kindest regards and thanks for considering Julien -------- Music was my first love and it will be my last (John Miles) ======== FIND MY WEB-PROJECT AT: ======== http://ltsb.sourceforge.net the Linux TextBased Studio guide ======= AND MY PERSONAL PAGES AT: ======= http://www.juliencoder.de
