TEAC IF-FW/DMmkII IF-FW/DMmkII release notes version 1.22 - Page 5

Release Notes powered off and on in order to regain connectivity. This has been fixed. Large Memory Systems Problems with large memory systems have been fixed. Stability Overall stability has been improved. Control Panel The Control Panel now remembers where it was on the screen, and will open in the same position as the previous time, instead of always opening in the center of the screen. Known Issues This section describes the Known Issues for the latest IFFW/DMmkII drivers Known Issues in V1.21 ªª Windows Driver DPC Spike Checker application On some computers, an error might occur with the DPC Spike Checker and it might not start. If this should occur, install the file that can be downloaded using the following link. http://www.microsoft.com/downloads/details.aspx? displaylang=en&FamilyID=766a6af7-ec73-40ff-b0729112bab119c2 Select "vcredist_x86.exe" for Vista 32-bit or Windows 7 32-bit, and select "vcredist_x64.exe" for Vista 64-bit or Windows 7 64-bit. Known Issues in V1.20 ªª Windows Driver Installation when Windows is set to 2xFS rates If the Windows WDM Audio sub-system is running at 2xFS rates (88.2 kHz or 96 kHz) when installing or upgrading the IF-FW/DMmkII driver, WDM audio will be silent after installation. To recover, it is necessary to change the WDM sample rate to a 1xFS rate (44.1 kHz or 48 kHz) and then return to the desired 2xFS rate (88.2 kHz or 96 kHz) Setting the DM-3200/DM-4800 sampling frequency when using Windows Vista or Windows 7 In Windows Vista or Windows 7, if the selected sampling frequencies set in the Advanced tab in the Properties window for the IF-FW/DMmkII in the Playback tab of the Sound Control Panel and the DM-3200/DM-4800 are different, the Advanced tab will not appear. In this case, change the DM-3200/DM-4800 sampling frequency first to show the Advanced tab. (See "Changing from 44.1 kHz/48 kHz to 88.2 kHz/96 kHz" on page 2 of this document.) Operation cannot be guaranteed if the sampling frequency is not set the same for Windows and the DM-3200/ DM-4800. Always set the sampling frequency the same for both Windows and the DM-3200/DM-4800. DAW Performance Performance with Sonar on Windows varies greatly. V1.20 works well with both 32 bit and 64 bit versions of Cubase. A higher performance CPU may be required for higher channel count and 96 kHz operation under Sonar. TASCAM will continue to improve the performance of the driver to enable higher channel count and FS combinations on all DAW platforms. Windows XP Service Pack 2 Upgrading to Windows XP 32 bit edition Service Pack 2 can cause FireWire 800 ports to be reset to FireWire 100 speeds, preventing the IF-FW/DMmkII from locking and passing audio correctly. See http://support.microsoft.com/ kb/885222 for a solution. Windows XP Service Pack 3 Upgrading to Windows XP 32 bit edition Service Pack 3 can also cause FireWire 800 ports to be reset to FireWire 100 speeds, preventing the IF-FW/DMmkII from locking and passing audio correctly. See for a solution. Boot Camp Beta versions of Apple's Boot Camp (a set of drivers that allow Windows OSes to be installed on some Apple Mac hardware) have FireWire chipset drivers that are not compatible with the IF-FW/DMmkII Windows drivers. Boot Camp from OS X Leopard works for some models of Mac hardware, but TASCAM customer support does not provide support for these configurations. ªª Windows and Mac VST System Link "VST System Link" functionality in Cubase 4 and other apps may cause unexpected channel assignments in your DAW. Please check these settings if audio is not appearing in expected channels. ªª Incompatible FireWire Chipsets Symptoms of an incompatible FireWire chipset include the "Audio Dropouts" number in the Control Panel increasing without bound even at system idle, unrecognized card even when plugged in, device not locking, or dropouts. Some chipsets have interactions with the motherboard configuration. Some chipsets will work better at reduced channel count or FS.
