Greetings, My local WalMart is selling off some HP notebooks for drastically slashed prices. One has an AMD turion and nVidia graphics, and it looks like it would fit my needs. Is there any particular reason I should *not* buy an HP notebook for running Linux audio apps ? I won't be using the internal sound hardware, so that's a non-issue. Best, dp

Expansion board (AEB8-O) for Hammerfall not working under alsa.

by Alex Montgomery

Hello, I have been using my hammerfall light (digi9636) under linux for quite some time to record s/pdif. I recently got an expansion board (AEB8-O) to use the hammerfall for output as well. I cannot get it to output music in alsa, and I'm not sure why. The really confusing part is that I can get a faint and very distorted sound out of the board if I intentionally reverse the wire (ground/signal polarity) between the hammerfall and the expansion board. I don't see any settings that are relevant to this sort of output in alsamixer, Anyone have any ideas? Here is what I did. I connected the boards and powered up my machine. Both green and red lights were lit. I then started up JACK + Ardour and connected the outputs of my ardour master out to all of the sound outputs of the digi9636 and then started the music. I couldn't hear anything through my headphones connected to the AEB8-O no matter which port I used. I thought that I had perhaps reversed the polarity of the cable connecting the digi9636 to the AEB-O, so I turned off my machine and reversed the connector on the digi9636. When I powered up neither of the lights were lit. However, when I tried to play music, after about 15 seconds of play I could hear a very faint, very distorted version of the song I was trying to play. I turned off my machine and changed the jumpers on the AEB-O to the other decibel level (even though they seemed to be on the louder setting by default) and tried again with both polarity settings. I still had the green and red lights lit when the cable was set to the correct polarity and still no sound. When I reversed the polarity again, there was the same very faint distorted music after several seconds of silence, and still no lights. Can anyone help me? Thanks, -- Alex

Qmidiarp - documentation

by Matthew Smith

Hi All I'm giving some fairly serious consideration to acquiring a second-hand synth with an arpeggiator, partly so that it gets me an arpeggiator, partly so that I've actually got some physical knobs that I can twiddle to change parameters in real-time. Before doing this, however, I thought that I would have a look at Qmidiarp. I have fired this up, selected 'Add Arp' and am now thinking to myself "now what?" There is no help in the application, 'man qmidiarp' gets me nothing and searching for documentation just gets me to the Sourceforge page for AlsaModularSynth. Unfortunately the documentation page there doesn't mention qmidiarp. So, can anyone point me to documentation for this, or does it not exist?

Linux-Produced CD Released on Albany

by Greg Wilder

"Chamber Music of Jeremy Gill" was released on the Albany record label today. I served as co-producer and recording engineer for this project which features performances from some of the finest chamber music soloists and ensembles on stage today. (Parker String Quartet, Mimi Stillman, Charles Abramovic, and the Extension Brass Ensemble) http://www.albanyrecords.com/Merchant2/merchant.mvc?Screen=PROD&Store_Code=… As testament to the incredible advancements within the open source audio community in recent years, this project was recorded and mastered using exclusively OSS. Specifically, the sessions were tracked (24bit/88.2kHz) in Ardour and mastered using Jamin and TimeMachine. Additionally, all computers involved in the production process were running Studio64, a Debian-based multimedia distribution of GNU/Linux. http://www.amazon.com/Jeremy-Gill-Chamber-Music/dp/B001GWS5A8/ref=pd_bbs_sr… Best, Greg -- Dr. Greg Wilder, CTO & Co-Founder Orpheus Media Research, LLC http://www.orpheusmediaresearch.com/ +1 215-764-6057 (office) +1 215-205-2893 (cell)

Re: [LAU] Intel-HDA sound issues

Quoth I: >> Whilst it is possible that someone out there may have this working >> with Jack (and a realtime kernel), I have yet to meet them. Quoth Ronald Stewart at 2008-10-22 07:49... > we got it working, you need good ol' 64studio RT.. There you go - so it can be done. Thanks Ron. Think I'll stick to my external card though - better connectors, headphone monitor, etc. (And hooked directly into a Soundcraft Compact 10 mixer.) One day I might actually get the time to use all this - haven't even had the chance build myself a non-crashing Rosegarden yet :-( Cheers M -- Matthew Smith Smiffytech - Technology Consulting & Web Application Development Business: http://www.smiffytech.com/ Personal: http://www.smiffysplace.com/ LinkedIn: http://www.linkedin.com/in/smiffy

Tracks released since start of year

by Patrick Shirkey

Hi, After Dave Phillips last release I got to thinking that there is a complete lack AFAIK of mixes being done with the tracks that are being released. So, I would like to ask for a refresh of the best of the new tracks that were released since the start of the year. Once I have a list I will endeavor to build a DJ mix and put it online. In fact I will aim to make it a yearly mix as a round up of the stuff that has been done. This will not be released for sale like the CD that was made. It will simply be a mix of the tracks that have been released attempting to find a nice balance and showcase the quality work that is being done. I will work on it over the next couple of months with the goal of having it ready before end of year. I already have a few that I intend to use mostly from the past couple of months though. I'll be weeding through LAM too but some people here might have some favorites they would like to recommend or even some new releases that they would like to submit for listening pleasure. Cheers. -- Patrick Shirkey Boost Hardware Ltd.

Music made with Linux

by David Collins

Hi, here are three pieces made with a Debian system - mostly timidity++, RoseGarden, and ecasound. Two songs: - http://indigo.uk.to/~david/music/32/32-instrumental.ogg - http://indigo.uk.to/~david/music/68/68.ogg And a neo-classical piece: - http://indigo.uk.to/~david/music/36/36.ogg There are notes about the production of each piece in a 'NOTES' file in the corresponding HTTP directory ( e.g. http://indigo.uk.to/~david/music/32/NOTES ). I have very little experience with mastering, and the last piece in particular needs a lot of work. I don't have much time to work on these at the moment, but constructive criticism is welcome. Cheers David

I'm using a utility for my Yamaha QY70 inside Wine and with an Audiophile 2496 and it works very well (that software is an old Win 3.1 application, though). Mirko
