should also be a folder called DAB if it’s fitted with DAB capture, with
subdirectories in that for each ensemble. Note that the Guest account
does not need to be enabled on Flashlog 8, however File Sharing must be
turned on and Password-protected Sharing must be turned off. The Audio
folder should be shared with read access granted to Everyone.
If the logger is not visible on the network check that the TCP/IP protocol
is installed on the workstation and that the network cables are correctly
connected on both the workstation and the logger.
• Lost connection to Flashlog – check that the network cable has not
become disconnected from either the workstation or the Flashlog
itself. Another possible cause of this message is reboot or failure of the
Flashlog.
• Unable to open audio output device - this may be caused by the
sound card not being installed correctly in the workstation or another
application may be accessing it. Note that the sound card must support
48kHz sampling rate. Make sure that the correct default playback device
is selected in the Windows Control Panel if there are multiple devices
available.
• No more connections can be made to this remote computer at this
time because there are already as many connections as the computer
can accept – Windows XP and Windows Vista both limit the number of
concurrent network connections to ten, while on Windows 7 and 8 the
limit is twenty. Flashback maintains a connection to the logger whenever
a channel is selected. If simultaneous playback on more workstations is
necessary, it will be necessary to upgrade the Flashlog operating system
to the equivalent server version and purchase the required number of
CALs.
• No sound when playing back - check that the speakers or headphones
are correctly connected and that the volume setting on the PC is set
correctly. Try running other applications that generate sounds to see if
the problem affects them as well. Check that the correct playback device
is selected in the Windows Control Panel.
• There are occasional gaps in the replayed audio - this may be caused
by other applications running on the workstation that are consuming
excessive processor time or you may have insufficient available network
bandwidth. Audio files are stored on Flashlog 5 as either 64 kilobits per
second (standard 13kHz bandwidth) or 128 kilobits per second (optional
18kHz bandwidth). Flashlog 6 uses 128kbps as standard. On Flashlog
7 and 8, the compression rate for line channels is configured from the
Flashlog Sources window, while AM capture channels use 32kbps, FM
capture channels use 64kbps and DAB+ / DAB capture channels are
stored at their broadcast rate.
• Note that Flashback 8 will not work on Windows 2000, as the current
Windows Media codecs are not supported on that platform.
