    1313If you don't already have an audio card, or you are shopping for a system board with onboard audio, you should review our [SupportedHardware Supported Hardware Matrix].

    15 Generally, current (new, off-the-shelf, 4th quarter, 2008) audio cards come in two basic flavors: [http://en.wikipedia.org/wiki/Intel_High_Definition_Audio HDA] and [http://en.wikipedia.org/wiki/AC97 AC'97]. HDA (High Definition Audio) is a newer spec defined by Intel in 2004 which specifically brings the ability of more sound channels at higher quality than previously available. Naturally, this new functionality requires newer hardware and software support. The Uniaud Project is making great strides to support this newer specification, but there is still much work to be done.

    1717Non-HDA hardware in recent years has made use of the AC'97 codec developed by [http://en.wikipedia.org/wiki/Intel_Architecture_Labs Intel Architecture Labs] in 1997. Uniaud has fairly good support for AC'97 devices.
     
    2626  2. HDA based devices or Sound Blaster Audigy SE (the latter is probably less likely to result in a system hang, but more likely to currently result in no sound)

    28 == Driver Selection ==
    29 
    30 Once you decide on hardware, you essentially have two tracks to take for Uniaud (there may indeed be a vendor-supplied driver for your hardware, but right now, we are addressing the use of Uniaud):
    31 
    32   1. A non-HDA build of Uniaud, currently at the 1.1.4 RC6 level, and available [ftp://ftp.netlabs.org/pub/uniaud/uniaud114RC6.zip here], or
    33   2. The above overlaid with the latest (experimental) HDA-enabled uniaud32.sys, currently at the 1.9.6 level (see [VersioningInfo Versioning Info] for more details), which is available [http://download.smedley.info/uniaud32-1.9.6.zip here].
    34 
    3528== Basic Installation: Common ==
    3629
    37 Uniaud installs using the built-in multimedia installer in OS/2 or eComStation. Therefor, once you have downloaded the file(s) mentioned above, simply unzip the 1.1.4 package to a safe place and run install.cmd from that directory. This will launch the multimedia installer and guide you through the process.
    38 
    39 If you are '''not''' installing support for an HDA card, then simply reboot at the end of the installation; you are likely done (restarting the desktop will not suffice, as the driver needs to be loaded from CONFIG.SYS). If you '''are''' installing HDA support, then one file must be overlaid (see the next section for details). '''DO NOT REBOOT FOLLOWING THE INITIAL INSTALLATION.'''
    40 
    41 == Installing HDA Support ==
    42 
    43 To provide HDA support, you should download the (experimental) HDA-enabled uniaud32.sys as mentioned above. Unzip the distribution to a safe location, peruse the readme, and copy uniaud32.sys on top of the one previously installed in your \MMOS2 directory. Once this is done, as an added precaution, you may want to disable system sounds (these have been known to cause hangs as the desktop comes up, presumably due to the overlapping of them as one event follows quickly after the other). Shut down and reboot (the driver must be loaded from CONFIG.SYS, so merely restarting the desktop will not produce the desired effect).
     30Uniaud installs using the built-in multimedia installer in OS/2 or eComStation. Therefor, once you have downloaded the file(s) mentioned above, simply unzip the package to a safe place and run install.cmd from that directory. This will launch the multimedia installer and guide you through the process.
