A little more information is required to assist.
What OS version do you have. Did you change the OS version from the last time it worked.
What version of FLDIGI are you using.
You can get garbage output in the absents of a signal, that does not necessarily mean anything other then to say that the squelch is set low (Radio and/or FLDIGI).
Here is a simple test to rule out a few things.
Under Configure->Soundcard->Device settings (FLDIGI) select "Microphone" for Capture and "Speakers" for playback.
Place any headset/speakers to the computer with volume turned up in order to listen.
Copy this (following text, between the ----- lines)
------------------------
To be on not to be that is the question ^r
------------------------
Paste it into the transmit panel.
Do not hit transmit button yet, and turn off the connected transmitter if it's on.
From the FLDIGI's menu select "File->Audio->TX generate". When it asks for a save location, note file name and save it to the desktop.
Press the T/R (on FLDIGI).
Do you hear digital audio output from the speakers/headset and see a digital signal on the waterfall?
From the FLDIGI's menu select "File->Audio->TX generate" a second time (turning it off).
Do not change the modem used to make recording during playback.
From the FLDIGI's menu select "File->Audio->Playback" locate the audio file saved. Default name: generate.wav on desktop. Once found mouse click the file, and press open.
You will be asked if you want play the file indefinitely, your call as to which.
Do you see a digital signal on the water fall that matches what you sent? In the RX panel do you see the following text? "To be on not to be that is the question".
Select "File->Audio->Playback" a second time to disable indefinite playback.?
If you have a microphone connected, when speaking into it do you see any changes in the waterfall that a signal is present and correlates with your speaking?
If so, then the likely issue follows:
The Audio capture/playback device is not set to the correct device.
Which might imply,
? ? a) Select the correct audio device from the configure dialog (FLDIGI).
? ? b) You need to set permission for FLDIGI to have access to said device.
? ? c) You need a device driver is order have access to said device.
? ? d) Cable/Interface that connects between your radio and computer is; missing, loosely connected, or defective is some fashion.
? ? e) The radio is not set to take input/output from the computer interface. (Edit:Added)
Don't know how much more I can assist you as I'm a hand on person in order to troubleshoot issues. But, let me know if you need help on the stated corrective suggestions.
