Theres a problem with the state of Linux audio, and its not that it doesnt always work. The issue is that its overcomplicated. This soon becomes evident if you sit down with a piece of paper and try to draw the relationships between the technologies involved with taking audio from a music file to your speakers the diagram soon turns into a plate of knotted spaghetti. This is a failure because theres nothing intrinsically more complicated about audio than any other technology. It enters your Linux box at one point and leaves at another. If youve had enough of this mess and want to understand just how all the bits fit together, were here to help read on to learn exactly how Linux audio works If we were drawing the OSI model used to describe the networking framework that connects your machine to every other machine on the network, wed find clear strata, each with its own domain of processes and functionality. Theres very little overlap in layers, and you certainly dont find end user processes in layer seven messing with the electrical impulses of the raw bitstreams in layer one. Yet this is exactly what can happen with the Linux audio framework. There isnt even a clearly defined bottom level, with several audio technologies messing around with the kernel and your hardware independently. Linuxs audio architecture is more like the layers of the Earths crust than the network model, with lower levels occasionally erupting on to the surface, causing confusion and distress, and upper layers moving to displace the underlying technology that was originally hidden. The Open Sound Protocol, for example, used to be found at the kernel level talking to your hardware directly, but its now a compatibility layer that sits on top of ALSA. ALSA itself has a kernel level stack and a higher API for programmers to use, mixing drivers and hardware properties with the ability to play back surround sound or an MP3 codec. When most distributions stick Pulse. Ready for HD. GPU decoding on Windows Vista and 7, using DxVA2 for H. VC1 and MPEG2 GPU decoding on GNULinux, using VAAPI for H. VC1 and MPEG2. Want to ditch the desktop and just use your smartphone You can do that OWASP WebGoat Project. WebGoat 7. 1 has been released, this release contains a lot of bug fixes for 7. WebGoat 7 is the latest in a series of. Audio and GStreamer on top, you end up with a melting pot of instability with as much potential for destruction as the San Andreas fault. Heres a simplified view of the audio layers typically used in Linux. The deeper the layer, the closer to the hardware it is. ALSAINPUTS Pulse. Audio, Jack, GStreamer, Xine, SDL, ESDOUTPUTS Hardware, OSSAs Maria von Trapp said, Lets start at the very beginning. When it comes to modern Linux audio, the beginning is the Advanced Linux Sound Architecture, or ALSA. This connects to the Linux kernel and provides audio functionality to the rest of the system. But its also far more ambitious than a normal kernel driver it can mix, provide compatibility with other layers, create an API for programmers and work at such a low and stable latency that it can compete with the ASIO and Core. Audio equivalents on the Windows and OS X platforms. ALSA was designed to replace OSS. However, OSS isnt really dead, thanks to a compatibility layer in ALSA designed to enable older, OSS only applications to run. Its easiest to think of ALSA as the device driver layer of the Linux sound system. Your audio hardware needs a corresponding kernel module, prefixed with snd, and this needs to be loaded and running for anything to happen. This is why you need an ALSA kernel driver for any sound to be heard on your system, and why your laptop was mute for so long before someone thought of creating a driver for it.

Note If you dont already have. Fortunately, most distros will configure your devices and modules automatically. ALSA is responsible for translating your audio hardwares capabilities into a software API that the rest of your system uses to manipulate sound. It was designed to tackle many of the shortcomings of OSS and most other sound drivers at the time, the most notable of which was that only one application could access the hardware at a time. This is why a software component in ALSA needs to manages audio requests and understand your hardwares capabilities. If you want to play a game while listening to music from Amarok, for example, ALSA needs to be able to take both of these audio streams and mix them together in software, or use a hardware mixer on your soundcard to the same effect. M_2.jpg' alt='How To Install Projectm Windows' title='How To Install Projectm Windows' />ALSA can also manage up to eight audio devices and sometimes access the MIDI functionality on hardware, although this depends on the specifications of your hardwares audio driver and is becoming less important as computers get more powerful. This screenshot of Alsa Mixer shows off everything thats wrong with Linux audio it really doesnt need to be this complicated. Where ALSA does differ from the typical kernel moduledevice driver is in the way its partly user configurable. This is where the complexity in Linux audio starts to appear, because you can alter almost anything about your ALSA configuration by creating your own config file from how streams of audio are mixed together and which outputs they leave your system from, to the sample rate, bit depth and real time effects. Registrul Comertului Bacau Program here. ALSAs relative transparency, efficiency and flexibility have helped to make it the standard for Linux audio, and the layer that almost every other audio framework has to go through in order to communicate with the audio hardware. Pulse. Audio. INPUTS GStreamer, Xine, ALSAOUTPUTS ALSA, Jack, ESD, OSSIf youre thinking that things are going to get easier with ALSA safely behind us, youre sadly mistaken. ALSA covers most of the nuts and bolts of getting audio into and out of your machine, but you must navigate another layer of complexity. This is the domain of Pulse. Audio an attempt to bridge the gap between hardware and software capabilities, local and remote machines, and the contents of audio streams. It does for networked audio what ALSA does for multiple soundcards, and has become something of a standard across many Linux distros because of its flexibility. As with ALSA, this flexibility brings complexity, but the problem is compounded by Pulse. Audio because its more user facing. This means normal users are more likely to get tangled in its web. Most distros keep its configuration at arms length with the latest release of Ubuntu, for example, you might not even notice that Pulse. Audio is installed. If you click on the mixer applet to adjust your soundcards audio level, you get the ALSA panel, but what youre really seeing is ALSA going to Pulse. Audio, then back to ALSA a virtual device. At first glance, Pulse. Audio doesnt appear to add anything new to Linux audio, which is why it faces so much hostility. It doesnt simplify what we have already or make audio more robust, but it does add several important features. Its also the catch all layer for Linux audio applications, regardless of their individual capabilities or the specification of your hardware. Pulse. Audio is powerful, but often derided for making Linux audio even more complicated. If all applications used Pulse. Audio, things would be simple. Developers wouldnt need to worry about the complexities of other systems, because Pulse. Audio brings cross platform compatibility. But this is one of the main reasons why there are so many other audio solutions. Unlike ALSA, Pulse. Audio can run on multiple operating systems, including other POSIX platforms and Microsoft Windows. This means that if you build an application to use Pulse. Audio rather than ALSA, porting that application to a different platform should be easy. But theres a symbiotic relationship between ALSA and Pulse.
