Enlightened Sound Daemon was one of the earlier solutions to the old
"multiple programs can't open /dev/audio at once" problem that was once
a thing we had to worry about.
Eventually, it was adopted as part of GNOME. GNOME lost interest in it
about a decade ago and dropped it in favour of PulseAudio, newer
applications are generally uninterested in supporting it. Last release
was in 2008 and support for newer OS APIs is pretty nonexistent.
Several years ago the original website disappeared.

libao tried disable the macos plugin by setting a configure
environment variable that didn't work. This forces the option
off by the SUBST framework to edit the config file.
Fix segfaults when closing a driver that did not successfully open.
Fix Mac OS X AUHAL support to properly handle suspend/wakeup, headphone plug/unplug, other hardware events
Fix building Mac OS X driver AUHAL compilation for 10.5, restore Mac OS X 10.4 support
Add 24 bit playback to Pulse plugin
Fix compilation of sndio plugin
Fix 24 bit playback in ALSA plugin
Improve/correct latency setup in ALSA (see Trac #1762)
Also fixes crash in ogg123 with libao-pulse (Trac #1689)
changes:
-Added surround channel mapping API and capability
-New config file options
-misc updates and fixes
pkgsrc note: The format structure passed to ao_open_*() has grown a new
member ("matrix", for channel mapping). All client pkgs need to be
checked that it is at least zero-initialized.
0.8.8 - Thu May 24
- New win32 driver
- Few fixes and changes in autotools and configuration files.
0.8.7 - unreleased snapshot
- obsolete alsa device renamed to alsa05
- the 'alsa' device now uses the 0.9/1.0 API
- ALSA driver fixes
file's sole purpose was to provide a dependency on pkg-config and set
some environment variables. Instead, turn pkg-config into a "tool"
in the tools framework, where the pkg-config wrapper automatically
adds PKG_CONFIG_LIBDIR to the environment before invoking the real
pkg-config.
For all package Makefiles that included pkg-config/buildlink3.mk, remove
that inclusion and replace it with USE_TOOLS+=pkg-config.
when the header files are found. Bump its revision to 1 due to this.
This makes the libao package completely audio-output agnostic.
- Add a libao-macosx package containing the MacOS X plugin (sorry, untested).
- Add a libao-oss package containing the OSS plugin. While here, use
ossaudio.buildlink3.mk to determine the audio device instead of hardcoding
it in a patch.
- Add a libao-macosx package containing the Sun audio plugin (sorry, untested).
Change approved by silence on tech-pkg@ for quite a long time since my
proposal.
I'm doing these changes to cleanup the base libao package. Before these,
it contained a huge conditional to determine when the OSS and/or Sun
plugins were built, which often failed in untested platforms (PLIST
inconsistencies, for example). Having these plugins in independent packages
makes debugging easier, keeps the dependency tree clean and also lets us use
{ONLY,NOT}_FOR_PLATFORM directives to easily say where they work or don't.
0.8.6 - January 11, 2005
- Added Polypaudio driver(libao-polyp 0.4)
from Lennart Poettering
- Use esd_close() in the esd driver
- Broaden sample rate tolerance in the OSS driver for nForce
compatibility
* Support now for the ALSA 1.0 API
* ALSA mmap() mode can be enabled/disabled at runtime using "use_mmap" option.
* Patch to OSS plugin to fix skipping issues with some drivers (like emu10k1).
* Can build with --disable-esd option again
* Minor build fixes
* Incorporated OS X patches from the Fink team.
* AIX output plugin by Stefan Tibus.
* Improvements in plugin detection code by David Walser, especially
when ESD or aRts are present.
* NAS plugin from Antoine Mathys.
* Portability fixes for various platforms (including dlopen() bugs)
including HP-UX and *BSD.
* Memory/resource leak fixes
* Significant fixes to ALSA 0.9.x plugin by Kevin Cody, Jr. This
should fix stuttering audio for mpg321 users. The --enable-alsa09-mmap
option to ./configure turns on memory-mapped I/O. Note this is
an experimental feature and causes some problems with some sound
card drivers and also users of the dmix software mixer.
