Added --with-configdir and --with-plugindir options to configure
which specify the directories for config files and plugin objects
respectively. The default paths when these options are not
specified are unchanged.
- add long card name to device description
- create empty PCM plugin to allow right hint description parsing
- reorder devices in alsa.conf
- make namehint more configurable (using default.namehint.showall switch)
- add two levels basic and exteded for hints to default configuration files
- do not show direct device aliases
- removed all known memory leaks
Created a new rate converter plugin SDK.
A rate converter can be replaced as an extra plugin now.
The default rate converter is a built-in linear converter.
You can find a sample external converter in alsa-plugins package.
Add --enable-* and --with-pcm-plugins configure options for partial builds.
User can choose the core components (pcm, mixer, rawmidi, hwdep, seq, instr)
via --enable-xxx or --disable-xxx option. As default, all components are
enabled.
The PCM plugins to build can be selected via --with-pcm-plugins option.
For example, to build only rate and linear plugin, pass
--with-pcm-plugins=rate,linear
Passing "all" will select all plugins (it's the default value).
The plug plugin will select linear and copy plugins automatically.
The other auto conversions of plug plugin are enabled only when the
corresponding plugin is selected.
- added link/unlink/link_fd fast_ops callbacks
- moved code from snd_pcm_link to pcm_hw.c
- moved "empty" routines pointing to slave to pcm_generic.c
- introduced snd_pcm_generic_t
The softvol PCM plugin is added. It applies the software volume attenuation,
which may be useful for codecs without volume controls.
Currently, the control is only mono. The attenuation is applied to all
channels equally. The control is probed and automatically created
when not exists yet.
- added backward compatibility for older non-compatible functions
- added --with-compat-rc3 to configure script to build library
backwards compatible with 0.9.0rc3
- added symbol versioning like libc.so.6
- ALSA_0.9 - alsa base
- ALSA_0.9.0rc4 - first set of new functions (snd_pcm_hw_params_*)
The configuration root (snd_config) can be specified for the internal routines.
The pcm_hooks code was recoded (independent code moved to control/setup.c).
Improved the pcm_multi plugin (added master configuration).
