This news is coming a few days late, but the
ALSA project has quietly released ALSA 1.0.18a as a minor update to its collection of sound drivers for Linux. This isn't a major update but a collection of updates on top of
ALSA 1.0.18 final. Among the changes are build fixes against the
Linux 2.6.28 kernel, support for new ASICs,
Intel HDMI audio support, and new ASICs being supported by various drivers/codecs. This ALSA release does not incorporate
Creative's open-source X-Fi driver or any other
Sound Blaster X-Fi sound card support.
The change-log between ALSA 1.0.18 and 1.0.18a is available
here. Only the ALSA driver set has received this "a" postfix with no updates to the libraries, utilities, tools, or plug-ins for the Advanced Linux Sound Architecture.
