Free sound server software for linux

pita is client-server music player. A daemon process, pitad, maintains a queue of files which it plays through the sound system.

Various clients manipulate the daemon, adding songs, moving through the queue, etc.

YPlayer project is a simple GUI player that plays Y sound objects.

It uses the GTK+ toolKit and the YIFF sound server.

PulseAudio Preferences in short paprefs, is a simple GTK based configuration dialog for the PulseAudio sound server

Please note that this program can only configure local servers, and requires that a special module module-gconf is loaded in the sound server. (Since PulseAudio 0.9.5 this modules is loaded by default.)

Kickarts is a simple Kicker (KDE Panel) applet to control the aRts sound server.
It has basically the same features as the commandline program artshell.
It is useful for quickly suspending or terminating the sound server before using an app without an arts output.
Enhancements:
- Fixed a few bugs
- New option to "notify when an error occurs"
- The update delay for the status check loop can now be specified
- Status icons (stopped, suspended and started) are now pngs
- French translation

PulseAudio Device Chooser (padevchooser) is a simple GTK tool which registers an icon in the tray area and allows quick access to some features of the PulseAudio sound server.
Main features:
Notify about new sink/sources becoming available on the LAN;
Quickly change the default PulseAudio sink/source/server assigned to the current X11 display, selecting devices available on the LAN;
Start the auxiliary tools PulseAudio Volume Control, PulseAudio Volume Meter, PulseAudio Manager

PulseAudio is a networked sound server for Linux and other Unix like operating systems. PulseAudio is intended to be an improved drop-in replacement for the Enlightened Sound Daemon (ESOUND).
Main features:
- Extensible plugin architecture (by loading dynamic loadable modules with dlopen())
- Support for more than one sink/source
- Better low latency behaviour
- Embedabble into other software (the core is available as C library)
- Completely asynchronous C API
- Simple command line interface for reconfiguring the daemon while running
- Flexible, implicit sample type conversion and resampling
- "Zero-Copy" architecture
- Module autoloading
- Very accurate latency measurement for playback and recording.
- May be used to combine multiple sound cards to one (with sample rate adjustment)
- Client side latency interpolation
- Ability to fully synchronize multiple playback streams
Installation:
As this package is made with the GNU autotools you should run ./configure inside the distribution directory for configuring the source tree. After that you should run make for compilation and make install (as root) for installation of polypaudio.
Enhancements:
- padsp has support for SNDCTL_DSP_SETTRIGGER, SNDCTL_DSP_SETDUPLEX, and SNDCTL_DSP_GETOPTR.
- A new ".ifexists" directive has been added to the CLI language for conditional configuration based on file existence.
- FLOAT32RE sample type support has been added.
- There are other bugfixes, cleanups, and portability fixes.

Ice Sound Manager was designed to ease the management of sound events, sound themes, and the IceSound server in the IceWM environment under Linux/Unix. It is also intended to be an improvement upon the noble, but primitive icesndcfg.
The main improvements over icesndcfg include a support for sound event "themes", more comprehensive help, easy management and configuration of the IceSound server, a cleaner GUI interface, automatic starting of the IceSound server, and a more conservative approach to disk space usage. In addition, Ice Sound Manager includes a built-in "Setup" program which runs the first time you run Ice Sound Manager.
The application is written in Python (making it more easily ported across various platforms and architectures) and uses GTK through the PyGTK libraries. This application is available in both .tar.bz2, RPM, and static binary (for people without Python/PyGtk).
Please note that the tar.gz file does NOT need to be compiled (this is python, remember). System requirements are as follows: Python 2.2, PyGTK-2 1.9.9/2.0.0, IceWM (or IceWM-Gnome) 1.2.0 or better - with the IceSound Server executable (generally called, icesound or icesound-gnome). IceWM version 1.2.6 or better is highly recommended.
NONE of the following is required: Gnome, Gnome libs, or PyGnome (python-gnome). This application has NOT been tested with earlier versions of Python, IceWM, PyGTK, and IceSound Server. I cant say that it wont work with earlier versions, but I certainly cant say that it will. This application has NO dependencies on Gnome. 8-)

Ice Sound Manager has been designed and tested in the following environment(s): Mandrake 8.1, SuSe 8.1, Kernel 2.4.8 / 2.4.19, Glibc 2.2.4 / 2.2.5, XFree86 4.0.1 - 4.3.0, Python 2.2 - 2.2.1, PyGtk 0.6.9/PyGtk-2 2.0.0, Gtk version 1.2.8-4-1.2.10, Gtk+2 version 2.0.6, IceWM 1.0.9 - 1.2.15, IceWM-Gnome 1.0.9 / 1.2.2, with both icesound and icesound-gnome sound server executables. The test computers (3) were all Pentium 1, ranging in memory from 64MB to 256MB - nothing spectacular. It should run well on very old computers.
Requierments:
- Access to a Bash shell (very important), Python (2.2 or better), PyGtk-2 (1.9.9/2.0.0 or better), and Gtk+ 2.0.6 or better - neither Gnome nor PyGnome is required. (IceWMCP versions 2.5 and earlier require Gtk+1 and PyGtk-1 0.6.9) Repeat: IceWM requires NOTHING gnome-related.
- Also, your version of PyGtk should have the Gdk-Pixbuf modules on your system. Please run ALL IceWMCP programs from a BASH shell: Using other shells such as ksh, pdksh, csh, tcsh, etc. is likely to cause problems. If your IceWMCP programs have trouble launching other applications, it is most likely because you are using something other than a Bash (/bin/bash) shell. Run the programs from Bash...period! If you attempt to run the application and get ANY kind of error that says something like "Import Error", it means YOU do not have all the necessary Python libraries installed or do not have them installed correctly: This is NOT a bug, so do not file a bug report when you dont have the necessary software properly installed. Getting Python and PyGtk and getting them setup right is YOUR business. DO NOT ask for help installing Python, PyGtk, or GdkPixbuf. I recommend you get them from: http://speakeasy.rpmfind.net. If you are using a Python version lower than 2.2 and are too lazy to upgrade, use the "binary" distribution of IceWM Control Panel, or dont bother at all. NOTE: These requirements apply only to the standard pure-python version of IceWM Control Panel. Compiled, binary copies of IceWM Control Panel are stand-alone executables that do NOT require Python or PyGtk.
- Disk space requirements: The standard, pure-Python version of IceWM Control Panel uses approximately 1.75-2.2 MB of disk space - very small! The compiled, binary version of IceWM Control Panel uses about 3.7 MB of disk space. Yes, the binary version is large, so people too lazy or impatient to install Python and PyGtk properly and choose to use the stand-alone binary version will pay with disk space. At last check, the Hardware (or System) plug-in uses about 1.9 MB of disk space (most of it being the hardware ID data file).
