Troubleshooting Linux Audio, Part 1
622274
I have a friend who has had nothing but nightmares result from his attempts at setting up the fabled low-latency high-performance Linux audio system. In sympathy with his plight I present here a primer in three parts for troubleshooting common and uncommon problems with the Linux sound system. Parts 1 &amp; 2 will present programs used to analyze and configure your audio setup. Part 3 will list the most frequently encountered problems along with their suggested solutions. This week, Part 1 introduces some useful system analysis tools and utilities with graphic user interfaces.

This week in my random survey of activity on the mail-lists for Linux sound &amp; music software I'll look at two very different software drum machines and a keystroke macro that enters LilyPond music notation into an Open Office text document. And if that isn't enough I've included four thrilling screenshots and links to three entertaining audio files to entice and maintain your interest. Read on for more...

Today we released version 1.6.3 of Streamline, a stream-based network subsystem for Linux.   This first release in over a half year has been thorougly stress-tested, so it should be more stable. New features include support for named and unnamed pipes, the full POSIX file IO interface, a write-after-read optimization similar to splicing, a method for catching HTTP GET requests and self-resizing (based on load) ringbuffer designs. Please read the changelog for more details.

The other day I was thinking about all the edge-cases within Linux and how there are hundreds of little commands and tricks.  I these know now but only after using UNIX for more than 15 years now (has it been that long!).  I wish I would have known all these tricks when I was just getting started.  This is similar to Danny O'Briens Life Hacks  but since so many of us spend our life tied to our shell these are essentially "Shell Hacks".  NetCat is one example.  Very powerful tool with a simple syntax.  Just run 'nc' and you can connect to a host/port and interact with it manually.  You could even write an HTTP client with bash if you really wanted to.  The zsh  shell looks like it might becom ...

Chris Hartjes has posted again about the "rebirth" of a Zend Framework component he's worked on - the Zend_Service_Audioscrobbler.   So, dear readers, I received some nice emails and comments from those you have used Zend_Service_Audioscrobbler, along with having a nice email conversation with Wil Sinclair from Zend.   He still wants to "rip things up and start over", but has decided on a slightly different route - mapping the older function calls to the new ones via a __call catch and including a message stating that the older function call would be deprecated.

Xmod makes compressed audio sound better than CD. Allegedly Creative yesterday said it plans to offer an external sound module incorporating its X-Fi audio enhancement system, a technology it claims can make even lossy compressed audio formats like MP3 and AAC sound better than the CDs they were ripped from - and, indeed, the studios they were recorded in.â¦

Development of native Linux audio plugins and softsynths may not be so relentlessly rapid as it is in the Windows and Mac sound software worlds, but new things do appear. This week I profile a cool new (well, relatively new) Linux softsynth, William Weston's Phase Harmonic Advanced Synthesis EXperiment, also known as Phasex.

I bought myself a neat toy the other week: a Creative Nomad MuVo MP3 player. It's about the size of a Zippo lighter and it plugs into my PC's USB port. I drag and drop my music files (actually audiobooks) onto it and then I can listen for hours.
