Thanks all for your help. In the end, I have finally managed - with the help of Norman's e-mail and Blazie Technical Support - to fix my problem. I have a cassette to MP3 converter connected to my machine via USB (with accompanying software installed). This has been in place for a number of months now and has worked perfectly alongside Jaws, however after ghosting my hard drive, I needed to re-install Jaws. When I did so, the software already in place told the now new Jaws installation to use the USB Audio Codec assigned to the cassette converter in preference to my computer's on-board sound card. This was however only the case when the cassette converter was plugged in. It was for this reason that the speech worked fine for the first couple of days after I copied my hard drive and re-installed Jaws from disk. This was before I re-connected the cassette converter. The re-connection prompted Jaws to use the USB Audio Codec (which is not attached to any speakers) in preference to the on-board sound card on startup. To fix the problem, I followed Norman's suggestion to actively tell Jaws which sound card to use. Not being too familiar with the inner workings of Jaws, I asked Blazie Technical Support to talk me through the process. For anybody interested, here's what I did, step-by-step (for Windows XP): 1) I opened 'Control Panel' from the Start Menu and went to 'Sounds and Audio Devices' 2) I selected the 'Audio' tab to find out what my 'Sound playback Default device' was. It is a Realtek AC97 Audio. 3) Then I went to the Jaws installation folder (for me, this is on the C: drive under c:\Program Files\Freedom Scientific\JAWS\8.0) and opened the file 'JFW.ini' using the Windows Notepad programme. 4) To tell Jaws which sound card to use, I then had to scroll down to the section concerning "Synth1". This had lines beginning with "Synth1Name=", "Synth1LongName=" and "Synth1Driver=". 5) I then inserted a new line after "Synth1Driver=" and before "Synth2Name=" which reads as follows: Synth1Port=<Sound Card Name> For "Sound Card Name, I inserted insert the name of my Sound Card. It now reads: Synth1Port=Realtek AC97 Audio This has done the trick and I am now much less flabbergasted. Once again, thanks for your help.
