Uniaud, Universal Audio Driver

Uniaud for OS/2 Introduction ============= Uniaud is a Universal Audio Support Driver for OS/2. Uniaud was a project created by InnoTek Systemberatung GmbH, now hosted by Netlabs. Uniaud is based on the Linux ALSA project. Uniaud supports a broad range of PCI audio cards/chipsets, including AC'97 and HDA audio codecs. AC'97 audio codecs will be found in systems with integrated (onboard) audio, typically built up through 2004. HDA codecs will be found in modern systems with integrated audio, built during or after 2004. Uniaud also supports some older audio hardware.

Installation ============ The Uniaud distribution comes in a self executing Warpin installer package. Simply execute to install or update. The installer will automatically detect if Uniaud is already installed and will choose to either update the existing installation or create a new installation. Then simply reboot at the end of the installation. Restarting the desktop will not suffice, as the driver needs to be loaded from CONFIG.SYS. WARNING: If you are using ACPI.PSD make sure it is version 3.23.04 or later or kernel traps may occur when running these drivers. Driver Command Line Options =========================== DEVICE=x:\MMOS2\UNIAUD32.SYS /A:0 /V /C:CARDNAME - /A:n - Use audio adapter n where the first adapter is 0. - /V - Verbose DEVICE=x:\MMOS2\UNIAUD16.SYS /V /C /M /L - /V - Verbose - /C - Enable CD output - /M - Enable Microphone output - /L - Enable Line-In output Default: /C ((verbose messages; CD output enabled) Removal ======= To temporarily disable Uniaud, simply comment the following two lines in CONFIG.SYS: DEVICE=x:\MMOS2\UNIAUD32.SYS DEVICE=x:\MMOS2\UNIAUD16.SYS To uninstall Uniaud two steps are required. These steps must be performed in the order shown below. 1. To remove the MMPM configuration, change directory to the following directory on your boot drive: \MMOS2\INSTALL\UNIAUD Then run uninstal.exe 2. To remove the files from your disk, run Warpin and uninstall the UNIAUD package. If there is no uninstal.exe program in \MMOS2\INSTALL\UNIAUD, or if there is no \MMOS2\INSTALL\UNIAUD directory on your system, simply re-install the latest official Uniaud Warpin package. This will create the necessary files and then you can use the above procedure to uninstall Uniaud. Getting Support and Reporting Problems ====================================== Known Problems with v3.01.xx versions ------------------------------------- * On a T-60, sound only works from a cold boot from power off. The older v2.02.06 works okay on a T-60, so if this bothers you please use the older version. More information can be found in the the Uniaud support wiki at: https://www.arcanoae.com/wiki/uniaud/ For additional information and to report problems please visit: http://trac.netlabs.org/uniaud Change Log ========== Uniaud32 v.3.01.02 24-Jul-2021 - David Azarewicz Update from Paul Smedley using audio code from Linux v5.10.50 Uniaud32 v.3.01.01 18-Mar-2021 - David Azarewicz Major update from Paul Smedley using audio code from Linux v5.10.20 Uniaud32 v.2.02.06 06-May-2020 - David Azarewicz Some minor mixer updates. Uniaud32 v.2.02.05 01-Sep-2018 - David Azarewicz Removed broken /C switch. Added ens1371 driver. Uniaud32 v.2.02.04 06-Jan-2018 - David Azarewicz Misc minor changes for specific Intel HDA systems (From Andy). Added limited MSI support.

UniLog.cmd Issue Reporting Package for UNIAUD This package is for users of UNIAUD who wish to report a problem. If UNIAUD does not work correctly for you, please open a ticket at http://svn.netlabs.org/uniaud/report If you don't have a login, use guest/netlabs To create the necessary log for tracking the issue, please unzip all files in this package in a temporary directory and run UniLog.cmd. If you already have PCI.EXE installed on your system, you can copy UniLog.cmd to any directory in your PATH. UniLog.cmd creates a log file which you should attach to your Ticket in the Trac system. The most useful logs are generated with the debug build of uniaud16 and uniaud32, also available from Netlabs ftp. For problems related to specific hardware, if possible, test it under Linux. There are a number of bootable livecd's that can be used without installing anything to your hard drive. A problem which also occurs in Linux is a bug in ALSA, not in Uniaud.

Multichannel Testing tool for Uniaud Propose: This tool useful for setting up/testing multichannel environment. It requires UNIAUD audio driver and latest UNIAUD API (uniaud.dll from March 2006 or later). The tool is Presentetion Manager application. Usage: Run MULTTEST.EXE . It will open PM window with an room entire. To test separate channels just click on appropriate speaker. To test Subwoofer click on white screen. If you have multichannel card with number > 0, start the tool with command line parameter -dev<card id>: MULTTEST.EXE -dev1 This will use device number 1 To check if device support 6 channels, use UNIMIX.EXE tool: unimix.exe -pcms and check for PCM PLAY section. If you see something like: PCM dev name: [NVidia CK804] mixer [subdevice #0] PLAY streams: 1 channels: from 2 to 6 rates: from 48000 to 96000 then you lucky sotb! :) Problems: The tool doesnt work (and never will) with MMOS2/DART. The tool works only with 6 channels environment The tool tested only with Nvidia4/Cmedia-MC6/SB Live! If something wrong, run "MULTTEST.EXE > out.log" then send me out.log file Contacts: Vlad Stelmahovsky aka Vladest vladest@netlabs.org Thank you for your cooperation (c) 5th element
