PCMCIA DSP SOUND CARD OS/2 WARP Support Software INSTALLATION: The PCMCIA DSP Sound Card support software is for use with OS/2 Warp only. Before installation, make sure that both OS/2 PCMCIA Card and Socket Services and the OS/2 Multimedia Support Software (MMPM/2) are installed. These components can be installed through the SELECTIVE INSTALL program found in the SYSTEM SETUP folder. See your OS/2 Warp documentation for details. Installing the support software is a 2-stage process outlined below. The first stage is to install the device drivers for the PCMCIA DSP Sound Card followed by the second stage of installing the MMPM/2 extensions. Approximately 6 MB of disk space is required, most of it for the wavetable sample library. If you have already installed Windows 3.1 support, the install program will find the existing wavetable sample library and point the OS/2 support software to that directory (and save several megabytes of disk space). 1. Insert the PCMCIA DSP SOUNDCARD into your computer. 2. From an OS/2 command prompt, run the SETUP.EXE program on the PCMCIA DSP Sound Card OS/2 Support Software diskette. Follow the on-screen prompts. When the install program exits, reboot your machine. 3. Open MULTIMEDIA APPLICATION INSTALL (MINSTALL.EXE) in the MULTIMEDIA folder on your desktop. Make sure the PCMCIA DSP Sound Card OS/2 Support Software diskette is inserted in your floppy drive and select A: (or B:) as the source drive. PCMCIA DSP SOUNDCARD SOFTWARE will be selected for installation. Click the INSTALL button and follow the prompts. You will be instructed to reboot your computer when the installation is complete. 4. Your OS/2 Warp system is now enabled to use the PCMCIA DSP Sound Card! Try the DIGITAL AUDIO and MIDI applications in your MULTIMEDIA folder! See your Warp documentation for details on using these applications. OPERATION NOTES: 1. The PCMCIA DSP Sound Card Support Software provides support for native OS/2 applications only. No DOS or Win-OS/2 sessions are supported. 2. Do not remove the PCMCIA DSP Sound Card from your computer if any audio applications (such as DIGITAL AUDIO or MIDI) are open. Failing to close these applications before removing the card may cause audio support to fail when the card is later inserted. In addition, audio applications should not be started if the PCMCIA DSP Sound Card is not inserted. The PCMCIA DSP Sound Card may be removed and/or inserted freely if all audio applications are closed. ** IT IS RECOMMENDED THAT YOU INSERT THE PCMCIA DSP SOUND CARD BEFORE ** ** STARTING OS/2 WARP AND DO NOT REMOVE IT! ** 3. Starting OS/2 Warp without the PCMCIA DSP Sound Card inserted can cause audio support to fail. To avoid this problem, either a) disable system sounds (using the SOUND application in the MULTIMEDIA folder) or b) make sure that the PCMCIA DSP Sound Card is inserted when you start Warp. This restriction should be removed in a future OS/2 Warp update. If you boot Warp with system sounds enabled and the PCMCIA DSP Sound Card is not inserted, you will still be able to have full WAV and MIDI support with the exception of system sounds. The first time you open an audio device (WAV or MIDI), the device open may fail: closing and reopening the audio application should restore audio capability. See note 6. If you have a WAV or MIDI device playing and system sounds are enabled, audio may fail after playing a system sound. A system reboot may be required to restore audio function. This problem should be resolved in a future update to OS/2 Warp. 4. Opening the MIDI device may consume a considerable amount of time (approx. 30 seconds), especially if your computer is relatively low on RAM (8MB or less). This is due to the large amount of wavetable data that is read from disk when the MIDI device is opened. Computers with small amounts of RAM and/or a heavy demand on system resources may also experience short pauses when playing MIDI files. NOTE: There will be a significant amount of disk activity while opening the MIDI device. 5. Try to limit the number of audio devices open at any given time. While the PCMCIA DSP Sound Card does support multiple WAV playback (3 WAV), simultaneous WAV playback/record (full-duplex operation) is not supported. Opening too many audio devices or using an unsupported combination (such as full-duplex) may cause one of the devices to "pause" until another device is closed. If a device does not recover, it may be necessary to close all audio-enabled applications and then reopen them to recover audio function. Removing and reinserting the PCMCIA DSP Sound Card (once all audio applications have been closed) may also be necessary to recover audio capability. 6. If your system stops responding (mouse pointer changes to the "wait clock" for a long period of time) when opening an audio device (see note 4) it may be necessary to close the application (using CTRL-ESC to bring up the task list) and retry. In some cases you may have to reboot your system to recover full audio functionality. 7. Simultaneous WAV and MIDI playback is supported with some restrictions. Due to DSP resource requirements, it is not possible for the PCMCIA DSP Sound Card to have devices for WAV playback, WAV record, and MIDI all open at one time. Some WAV-enabled applications (such as DIGITAL AUDIO) open a WAV device as both a playback and record device. This means that a MIDI device can not be opened until one of the WAV devices is closed. To enable simultaneous WAV and MIDI playback: a) Open DIGITAL AUDIO, select a WAV file, and play it. This will "close" the WAV record device. b) Open MIDI and select a MIDI file. c) Both applications will now be able to play their selected file. NOTE - opening another WAV file will reopen the WAV device and may cause your system to crash! These restrictions apply to the simultaneous use of the DIGITAL AUDIO and MIDI applications found in the MULTIMEDIA folder. Applications that open the WAV device as playback-only (such as a native OS/2 game) will be able to provide simultaneous WAV and MIDI playback. 8. Simultaneous recording and playback (full-duplex operation) is not supported. 9. The IBM ThinkPad 720 is not supported. 10. The optional external MIDI connection is not supported. 11. The optional joystick port is not supported.
