[linux-audio-user] How does one alter the main mixer volume (or any other mixer level) in ALSA from a command line (via a simple system call)?

by Ivica Bukvic

Hi all, I have this small question: Is it possible (I presume it is) to alter mixer settings in Alsa by invoking some kind of a system call using shell (i.e. how the RME hdsp can have its stuff altered)? If so, what is the range of values that describe the loudest and softest levels? Finally, are these levels standardized? Any help on this matter is greatly appreciated! Thank you! Sincerely, Ico P.S. Apologies for cross-posting.

[linux-audio-user] Jack gentoo ebuild

by Jon Ellis

I just checked a new (~X86 masked) ebuild into gentoo cvs for the 0.50.0 release. The old (0.34.0) ebuild is still there and will probably stay until i work out if anything is using it. If you know of any packages that rely on the 0.34.0 version please let me know. Cheers j.

[linux-audio-user] delta44 and direct recording

by John Bleichert

Hello All I'm evaluating a Delta44 sound card to use with Ardour and Audacity (Audacity until Ardour stabilizes, and maybe afterward). I've grabbed the manual for the 44 from the M-Audio site to check it out. The 2 example recording layouts they provide in the manual require an M-Audio 'Audio Buddy' (or something like it) to get a proper line level. now, I've been recording with my SBLive for a coupla years now and my guitar multi-effects pedal has given me the line level Ive needed. Will I actually need one of these Audio Buddy preamps? What have been the experiences here with and without them? Any? Also, I'll be adding a Behringer mixer to the setup - will I be able to drive the appropriate levels into the Delta44 from mic'ed guitar, bass, drums and vocals? Do I really need this Audio Buddy thing? It seems rather odd that it would be required and not a word about it spoken on the Dellta44's website. It was my intention to run all the instruments into the mixer (e.g. the Behringer UB1204) and then from the mixer to the inputs on the Delta44. Is this idea flawed? Advice appreciated. I'm willing to spend a few bucks on the card and mixer but I want to make sure I'm getting what I want. Thanks in advance for any advice or suggestions - JB # John Bleichert # http://vonbek.dhs.org/latest.jpg

[linux-audio-user] simple audio apps

by jdennett＠science.uva.nl

Hello, This is a question from someone who is interested in turning primarily speech recordings from a minidisk into mp3s, and editing them. In the editing I want do to simple things like fade, mix and cross fade, but nothing like set up wah-wah filters or what not: the recordings are interviews and some other "report-like" noises, and not music. My two questions are: (i) is there a simple record meter, so that when i get handed different MDs recorded in different ways, I can see what my mixer settings should be real time? (ii) i presently use audacity for my editor, am happy with it (bar its apparent inability to record mono mp3s at correct rate), but thought as i was posting, to ask for other suggestions (ie am i just happy in my ignorance :) ) thanks for any suggestions, jane

[linux-audio-user] Can't set input monitoring with ice1712 based card.

by Luke Yelavich

Hi folks I have compiled the latest 0.9rc of ALSA, on a system with kernel 2.4.20 patched with low-latency and pre-emptable kernel patch. I have a TerraTec DMX 6Fire 24/96 soundcard, which uses the Envy24 chipset. The card uses the snd-ice1712 module. I execute jack like this: jackd -d alsa -d hw:0 -p 512 -r 44100 & Jack starts fine, however when I try and run a client, in this case ZynAddSubfx, I occasionally get xruns, and a message saying "Cannot set input monitoring (No such file or directory)" I am unable to jack ZynAddSubfx to ALSA, as the jack portion of alsa-patch-bay tends to time out while attempting to patch the program. I am running all of this as root. Any ideas or suggestions are welcome. Thanks Luke (TheMuso)

[linux-audio-user] jackd, zynaddsubfx and iiwusynth

by Levi Burton

Hello, Has anyone gotten zynaddsubfx and/or iiwusynth to work with jack? The programs fire up fine, but they output no sound. I have tried zynaddsubfx 1.0.9 and the most recent cvs of iiwusynth (fluidsynth). I know i am calling jackd properly, because alsaplayer works fine with jackd, as well as ecasound. -- Levi Burton http://www.puresimplicity.net/~ldb/
