It wasn't. I experienced thirty seconds of hope when I saw this. But switching it to Yes didn't change anything. > arts.

When I play it back with a WAV player, I get no complaints about format or anything, but all it plays back is silence. I checked it with a Windows program that displays the actual waveform, and it agrees that the file is a valid WAV file containing silence. This is all going to turn out to be some really stupid, simple configuration option.... FWIW, this is all a stock LM 8.1 installation. Until I started trying to record, I hadn't messed with any of the sound settings at all. They are (or at least they were) all as set "out of the box". I'll take a look at your URLs over the weekend, when I've recovered a bit from all this trauma :-) Doc Evans -------------------------------------------------------------- Phone: +1 303 494 0394 Mobile: +1 720 839 8462 Fax: +1 781 240 0527 --------------------------------------------------------------
