1. Troubleshooting

1.1 Trouble Hearing Sound with Sound Finder or Music Box

    If you do not hear sound when using Sound Finder or 
    if Music Box cannot find your CD-ROM drive, ensure 
    that you have the following entries or files in the 
    appropriate locations:

    In the WIN.INI file in the Windows 3.1 directory: 

        [MCI extensions]
        wav=waveaudio
        mid=sequencer
        rmi=sequencer

    In the SYSTEM.INI file in the Windows 3.1 directory: 

        [MCI]
        CDAudio=mcicda.drv
        WaveAudio=mciwave.drv
        Sequencer=mciseq.drv

    In the Windows 3.1 system directory: 

    		MCICDA.DRV
    		MCIWAVE.DRV
    		MCISEQ.DRV

1.2 Windows on a Network Installation

    If you're running Windows from a network installation, you cannot
    play MIDI files.  You must install Windows on your local hard disk to
    play MIDI files.

    If you're running Windows from a network installation, CTL3D.DLL does
    not get copied to your hard disk.  Either install Windows on your local
    hard disk, or copy CTL3D.DLL to your Windows Sound System directory on
    your local hard disk.

1.3 Using Music Box with a Future Domain SCSI Card

    If you have a Future Domain SCSI card installed in your computer 
    and Music Box doesn't play, ensure that you have the latest version 
    of the CD-ROM driver, FDCD.SYS (version 2.23 or later). 

1.4 Using Quick Recorder with a 386 Computer with a 25 MHz or Lower CPU

    Quick Recorder cannot record reliably at high sampling rates on some
    computers, particulary 386 computers with 25 megahertz (MHz) or 
    lower CPUs. 

    To correct the problem:

    1. Record at a sampling rate lower than CD Quality (less than 44
       kHz). This reduces your computer's processing.

    2. Close other applications, if possible.

    3. If you must make CD-quality recordings, keep them as short
       as possible. 

1.5 Playing Stereophonic Files with a Monophonic Audio Board

    Quick Recorder cannot play some CD-quality stereophonic files in 
    Recorder view. Try playing these files using Sound Finder or use
    Quick Recorder in Expanded View.

1.6 Playing MIDI Files with Sound Blaster Pro Audio Hardware

    If you are using Sound Blaster Pro audio hardware, and you have 
    the microphone turned on in Voice Pilot, you will not be able to
    hear a MIDI file while it is playing. Turn off the microphone.

1.7 Opening More Than One Instance of a Quick Recorder File

    To open more than one instance of a Quick Recorder file, you must 
    have SHARE.EXE installed in MS-DOS.  For instructions on installing 
    SHARE.EXE, see the "MS-DOS User's Guide." 

1.8 Detecting Installed Hardware

    If your audio hardware does not function correctly, ensure 
    that you selected the right audio hardware when you ran Setup. 
    If an outdated driver is present, Setup may not detect the presence 
    of the correct audio hardware.

1.9 Playing 44kHz files with Sound Blaster Pro Audio Board
    
    Quick Recorder cannot play some 44kHz stereophonic files in
    Recorder view. Try playing these files using Sound Finder or use
    Quick Recorder in Expanded View.

__________________________________________________________________________

2. Voice Pilot

2.1  Using Multiple Mixer Devices

     Voice Pilot uses the mixer device with the lowest number (the one 
     listed in the first "mixerX=" line in your SYSTEM.INI file) that meets 
     its requirements. If you want to use a driver other than the default
     driver for your Voice Pilot input, manually renumber the "mixerX=" 
     lines in your SYSTEM.INI file so that the number of the mixer device 
     you want to use is the lowest.

2.2 Confirmation Option Limitations

    The Confirmation option cannot be used on commands that are not 
    top-level commands; that is, the Confirmation option can be used only 
    with commands that appear on the menu bar or with commands that are not 
    contained on menus.


2.3 Using Audio Cues

    If you are using Voice Pilot's audio cues, Voice Pilot may attempt to 
    sound a cue at the same time another application, or VoicePilot itself, 
    tries to issue a sound. As a result, you may not be able to use Voice 
    Pilot to start ProofReader or you may receive a warning that the device 
    is being used by another application. To correct this situation, in the 
    Audio Cues section of the Preferences dialog box, select None. 

__________________________________________________________________________

3. ProofReader

3.1 Versions Supported 

    ProofReader is supported only in Microsoft Excel version 3.0 or higher 
    and Lotus 1-2-3 for Windows versions 1.0, 1.0a, 1.1.01, and 4.

3.2 Using Multiple Instances 

    If you run more than one instance of Microsoft Excel or Lotus 1-2-3 
    for Windows, ProofReader is present only on the menu of the first 
    instance.

3.3 Installation Sequence

    You must install your Windows-based spreadsheet application before 
    installing ProofReader with the Windows Sound System Setup program.

3.4 Removing or Reinstalling ProofReader

    To remove or reinstall ProofReader for Microsoft Excel, see your 
    Microsoft Excel documentation for information on how to remove or 
    install an add-in.

    To remove or reinstall ProofReader for Lotus 1-2-3 for Windows
    (123RDR), see your Lotus 1-2-3 for Windows documentation for information 
    on how to remove or install an add-in.

3.5 ProofReader Dictionary for Non-U.S. English-Speaking Countries

    The ProofReader dictionary NON-US.DCT contains terms that
    accommodate the differences between English as spoken in the United
    States and English as spoken in some other English-speaking countries. 
    
    To use this dictionary, add it to the list of active ProofReader 
    dictionaries:  

    1. From the Microsoft Excel or Lotus 1-2-3 for Windows
       Proof menu, choose Options.

       The Options dialog box appears.  

    2. In the Category box, choose Dictionary.

       The Dictionaries dialog box appears.

    3. Choose Add Dictionary.

       The Add Dictionary dialog box appears.

    4. In the Directories box, choose the Windows Sound
       System directory (the default is C:\SNDSYS).
  
       NOTE: If you installed Windows Sound System
             in a directory other than C:\SNDSYS,
             choose the proper directory name.

       The list of available dictionaries (*.DCT files)
       appears in the File Name box.

    5. In the File Name box, select NON-US.DCT.

    6. Choose OK.

    7. Choose Done.

3.6 Using ProofReader for Lotus 1-2-3 for Windows and 
    International Country Settings

    Lotus 1-2-3 for Windows uses its own country settings, not 
    the country settings used by Windows. If ProofReader does 
    not read some numbers correctly, verify that the country 
    settings selected in the Windows Control Panel match the 
    country settings that are set for Lotus 1-2-3 for Windows.

3.7 Lotus 1-2-3 for Windows Release 4

    Lotus 1-2-3 Release 4 does not support accelerator keys for 
    add-ins, such as ProofReader.  Use the mouse or the arrow 
    and Enter keys to select commands.

__________________________________________________________________________

4. Using Windows Sound System with Microsoft Windows NT(TM)

   The Windows Sound System sound board can be used in ISA/EISA
   computers running Microsoft Windows NT. Sound applications 
   that are shipped with Windows NT play sounds through the 
   Windows Sound System sound board by using an audio driver 
   included with Windows NT. Windows NT-based applications that 
   use the Microsoft Windows version 3.1 Sound Application 
   Programming Interfaces (APIs) should operate properly with the 
   Windows Sound System sound board.
__________________________________________________________________________

5. Compatibility with Windows Sound System

5.1 Windows Sound System and Other Audio Drivers

    The Windows Sound System audio driver may conflict with other
    audio drivers. If you use multiple sound boards and drivers, 
    you may experience interrupt (IRQ) channel, I/O address, or 
    DMA channel conflicts that can cause your computer to stop 
    or to repeat sounds. Therefore, we recommend that you remove 
    all other audio drivers by using the Windows Control Panel 
    Drivers application. 

    If you remove an old audio board and install a new board, 
    you may have to manually remove the driver entries from 
    your SYSTEM.INI file.  

    For information on how to remove Windows Sound System software, 
    see DEINSTAL.TXT in your Windows Sound System directory (the 
    default is C:\SNDSYS).

5.2 Windows Sound System and MIDI Sequencing Software

    Windows Sound System is incompatible with certain Musical
    Instrument Digital Interface (MIDI) sequencing applications. 

    Sound Finder cannot play a file with an .MID or an .RMI 
    extension while a sequencing application is open, regardless 
    of whether a file is actually loaded into the sequencer. If 
    you want to use Sound Finder to browse MIDI files and other 
    types of files, close your sequencer first. Alternatively, 
    you can use your sequencing application to play MIDI files.

    Finale 2.2 for Windows from Coda Music Technology is compatible
    with the Windows Sound System sound board and software if you 
    modify the WIN.INI file. For more information on using 
    Finale for Windows or MusicProse for Windows with the 
    Windows Sound System sound board, contact Coda Music 
    Technology at (612) 937-9611. 

    If you experience difficulties while using your MIDI sequencer 
    with your Windows Sound System sound board:

    1. See the Windows Sound System documentation to ensure you 
       have installed and configured both the sound board and 
       the software properly.

    2. See the documentation for your sequencer. 

    3. If you continue to experience problems, contact Microsoft
       Product Support Services.

5.3 Potential IRQ Conflicts in IBM PC/AT Bus Class Computers

    IRQ 2 is unavailable to add-in cards on IBM PC/AT bus class 
    computers. If you are using an IBM PC/AT bus class computer 
    and you select IRQ 2, your selection defaults to IRQ 9.  

5.4 Installing EMM386 on Stacked Drives 

    Installing Windows Sound System on stacked drives and 
    running the MS-DOS Configuration program to enable 
    Sound Blaster compatiblity may cause your stacker drive 
    to load incorrectly. Stacked drives are often loaded 
    into UMB space; therefore, EMM386 must be present to 
    provide UMBs. Copy EMM386 onto a nonstacked boot drive. 
    The nonstacked drive is usually the drive that contains 
    the MS-DOS system files.

5.5 Using IRQ 7 on Gateway 2000 Computers

    Windows Sound System cannot use IRQ 7 on some Gateway 
    2000 computers. However, you may be able to make IRQ 7 
    available for use on such a computer by changing a 
    BIOS setting.  Contact your Gateway 2000 representative 
    to determine how to make IRQ 7 available. (For information
    on IRQ settings, see the "Microsoft Windows Sound 
    System Software User's Guide.")  

5.6 Using Windows Sound System in Windows Standard Mode 

    You cannot perform a sound check if you are running 
    Setup in Windows Standard mode.  To check hardware 
    operation, run Windows in Enhanced mode or use Sound 
    Finder or Quick Recorder to play a file. 

5.7 IRQ and DMA Conflicts on EISA Machines

    If an EISA machine is incorrectly configured, Windows 
    Sound System may report that all IRQ or DMA channels are 
    in use.

    To solve this problem:

    1. Use the EISA configuration utility supplied by your 
       hardware manufacturer to configure the computer properly. 
       This is the preferred solution.

    -or-

    2. Disable the EISA resource scan of SNDSYS.DRV and 
       VSNDSYS.386 by adding the EnableEISAResourceScan=FALSE 
       flag to the [SNDSYS.DRV] section of the SYSTEM.INI file.  
       Note that disabling this feature can cause problems with 
       enhanced SCSI adapters, such as the Adaptec 1742.

6. Removing Windows Sound System from Your Computer

   If you want to remove Windows Sound System from your computer, 
   see DEINSTAL.TXT, in your Windows Sound System directory 
   (C:\SNDSYS by default).
__________________________________________________________________________

7. Sound Blaster Pro, Sound Blaster 16, and Sound Blaster 
   16 ASP Issues

   Setting the MIDIInPersistence= variable in the [WSSSBPRO.DRV] 
   or [WSSSB16.DRV] section of your SYSTEM.INI file allows you 
   to configure the amount of data that will be processed in the 
   MIDI-in interrupt.  The default value is 50, the recommended 
   range is 50 to 1024. Decreasing this value may prevent the 
   MIDI-in device from being completely serviced and may 
   cause data loss or may stop input.  


__________________________________________________________________________

8. Sound Blaster Compatibility with the Windows Sound System Sound Board

8.1 Problems Playing Music  

    If your game offers the choice, select Ad Lib 
    compatibility for music output and Sound Blaster 
    compatibility for sound effects.  This will prevent 
    music from playing too slowly.

8.2 Using GAMES.PIF 
    
    If you're using a user-specified shell in MS-DOS, 
    ensure that the file GAMES.PIF (located in the directory 
    in which you installed Windows Sound System, C:SNDSYS 
    by default) references the same shell as your COMSPEC system 
    variable.  To edit the GAMES.PIF file, use Windows PIF 
    Editor. For more information on the COMSPEC system variable, 
    see your MS-DOS documentation.  

8.3 Choosing between Sound Blaster andSound Blaster Pro
    
    If your game offers choice between Sound Blaster and Sound
    Blaster Pro, you must select Sound Blaster, not Sound 
    Blaster Pro, as your audio board.

8.4 Playing Mickey's ABC
    
    Mickey's ABC cannot detect the presence of 
    the Windows Sound System sound board. However, it will 
    work correctly if you select Ad Lib compatibility 
    as the option for music.                       

8.5 Playing Alphabet Blocks
    
    If you experience problems playing Sierra On-Line 
    Alphabet Blocks with the Windows Sound System sound 
    board, add AcceptCloseSamplingRates=TRUE to the 
    [SNDSYS.DRV] section of the SYSTEM.INI file. 
    Alphabet Blocks uses a nonstandard sampling rate 
    that is not directly supported by the Windows Sound 
    System sound board. Setting this flag to true allows 
    the driver to accept sampling rates that are within 
    5% of the actual supported rate.

8.6 Playing Broderbund Games

    If you experience problems while playing Broderbund 
    games, set the VirtualHDIRQ=FALSE switch in the [386Enh]
    section of the SYSTEM.INI file.
