Hello everyone! I had a USB audio device here, a Zoom h4n, portable recorder/audio interface. When I connect it to my box, it shows up and ALSA finds it. First: ALSA can't open the mixer, no elemtns found, alsamixer says. Second: I can't use JACK with it, although I read on some forum, that a chap managed with Fedora FC6. JACK tells me something about broken pipe. It runs, but there's no sound and I definitely have to "killall -9" it. :-( I tried JACK with different period sizes (-p) and different frames per period (-n), different samplerates, although I can set these on the Zoom, before I connect it. As I said: ALSA can record from it and play sounds using it. Does anyone of you have an idea on the subject? Kindest regards 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

Laptop speakers nonfunctional, jacks functional

by Ludwig Maes

---------- Forwarded message ---------- From: Ludwig Maes <ludwig.maes(a)gmail.com> Date: 2009/6/26 Subject: Laptop speakers nonfunctional, jacks functional To: alsa-user(a)lists.sourceforge.net Realtek ALC888S (according to preinstalled Realtek HD audio manager on windows) visible jacks working, builtin laptop speakers and subwoofer silent. Running Ubuntu 9.04 compiled and installed alsa 1.0.20. http://www.alsa-project.org/db/?f=fb64ba9a8ab28d8c16532ece21e3adba7219e4b9 Notice it thinks it is ALC1200. I searched this and found it in patch_realtek.c, I changed the equality test so we would end up in ALC888 section... result was I got an extra volume control on mixer for BEEP. previously did not hear beeps when hitting down in terminal. BEEP is in headphones or line out. still not on speakers. aplay -l listed ALC888 too but codec#0 still showed ALC1200... I dont know the flow of information changes in ALSA to change this codec... I undid the equality test change and now its back to original realtek patch, recompiled reinstalled... added model=generic, to asound.state, this gave me more controls IIRC.. downloaded codecgraph utility, result: http://img20.imageshack.us/img20/8692/codec0.png I dont know how these codecgraphs work, but 4 jacks are right! the internal speakers appear twice?? how can one rewire these, or enable assuming dotted is disabled, does every amplifier triangle correspond to a volume control? is there a direct way to make changes? dmesg |grep hda: [ 16.172695] hda_codec: Unknown model for ALC883, trying auto-probe from BIOS... [ 18.037866] ALSA /usr/src/alsa/alsa-driver-1.0.20/pci/hda/../../alsa-kernel/pci/hda/hda_intel.c:636: hda_intel: azx_get_response timeout, switching to polling mode: last cmd=0x00bb0000 Realtek datasheet for ALC888S, reference design, if helpful: http://www.realtek.com.tw/products/productsView.aspx?Langid=1&PFid=28&Level… I am very willing to test proposals... friendly greetings, Ludwig

Are surge protectors insufficient to protect sensitive audio equipment? We have started to use surge protectors to connect all our electronics to outlets, and they seem to have helped immensely. they have something like $75,000 equipment warranties but i don't want to take chances with replacing or repairing my audio equipment (what a hassle!) if something does happen. on the other hand, i don't care if my tv gets fried :) ethan

Daemons, daemons...kill those daemons.

by Brent Busby

Now that I've gotten a pretty clear picture of the concensus about PulseAudio, I wondered about some of the other (new and old) sound facilities in Linux, and specifically wondered if being on a system like Gentoo where one can turn off build-time support for these things is a good idea. So... PortAudio: >From what I can see, this doesn't do much. It seems to provide an API of sorts that unifies Linux sound with sound on other operating systems. (For example, FreeBSD supports PortAudio, even though its an OSS-based system.) Then again, I thought Alsa's OSS emulation provided a '/dev/dsp' that did that already. Anyway... Is this bad? Has anyone had nearly the nightmares with PortAudio presence in a DAW system that's described from users of newer systems with PulseAudio? I don't want to incriminate it just because its name is similar. (Though I do find myself calling PortAudio "PulseAudio" by accident a lot. They really could have found a better name for that...) Gentoo has a USE flag to disable PortAudio, but I hesitate to do so if most of the apps these days are taking its presence as a given. I don't want to diverge from what's perceived as "normal" upstream more than necessary to achieve good results. Esound ("esd"): This is truly 90's technology that won't die, and we all know that. The question is, how much of an assumption is it in the apps (and in the Gnome desktop) to the extent that if it weren't there, there would be problems? Is it safe on a Gentoo system to globally ban build support for ESD? Sure, Alsa has its own mixer, but will the apps just transparently use it if ESD isn't around? This is really the gist of all my questions here: We know there are daemons we don't like. But which ones are safe to actually kill, and which ones do we still sadly depend on for something or other? Arts ("artsd"): I already have some doubts about eliminating this one, at least in any system that hopes to have a KDE desktop available. Even if we don't need it per se, KDE seems (at least to a naive user like me) to be deeply wedded to it. There are even direct mentions of artsd setup in some of the audio setup panels of the KDE Control Panel. Does banning Artsd support equal losing all desktop audio support in KDE? It looks like it might...experiences? I guess what I'm thinking is that it'd be nice to do a build in which everything but Alsa and Jack is banished to hell, but I'm wondering if that will leave some programs at a loss to find a mixer at all, and thus without sound. Ideally, all sound apps, regardless of what target they're expecting, ought to be able to transparently find the Alsa mixer, and multiplex with other apps to share access with it simultaneously, also without special setup. Does that work? (I'd even put up with artsd if I had to, since KDE seems to assume it, and since it doesn't seem to cause major problems...) -- + Brent A.

Re: [LAU] Paul Hindemith says hello

So true, that part. Writing for others is a mix of inspiration and damned hard work, and requires a strange combination of humility (listening to others), and enough bravado to follow your muse. Started this time last year with 8 songs. Cut back to 4. Wrote another 12. Cut back to 9. Sent demos of 9 songs to musos/engineers whose opinions matter to me. Cut down to 3 songs. (Which have all been re-recorded/arranged) Recorded another 10 songs. Keeping critiques of aforementioned friends in mind - back to 9 songs. Wrote another 5. Played and played and played those tracks to many people, noting what seemed to please and what didn´t. Down to 7 songs, in the process of writing one last piece, then call it a day and unleash my crap on the world. So that will be 35 odd full-recordings, many rerecordings and rearrangements to produce 8 tracks. That of course doesn´t include all the stuff I wrote and forgot about, or pieces that just don´t fit. Now that doesn't mean that the other pieces are necessarily "crap" - wrote a lovely Ben Fold's Five-style ballad for my gf - but she's the only one that will hear that. I believe, that after 35 years composing, 7 albums and thousands of performances with various long-haired groups that shall go unnamed, that only experience can really tell you if it's personal or public. And most of what I released when young should have never been let out of the rehearsal studio. (thus "unnamed groups") I remember Peter Gabriel saying something similar, but I can't find the interview in question. He was far more eloquent, though. - shane

Re: [LAU] someone awhile back posted about how to make a bootable Linux flash drive?

by david

Thanks. Using either 64Studio 2.1 DVD image and ArtistX 7.0 DVD ISO, it makes a bootable flash drive that proceeds to try to mount a cdrom. The second link doesn't seem to lead to any place to download IMG files, and it doesn't look like 64Studio provides any img files ... well, they talk about it but don't seem to provide them ...
