You should be able to access these from the control panel, and the display normally defaults to the play controls. There should be a menu item called Options, and, within that, properties.
Click on recording (rather than playback) and OK. Be sure the correct source is selected, that it is not muted, and that volume is set to the maximum.
I have a 98SE with a SBAudioPCI64DLegacy drive installed. I have Wave Lab installed to edit and record vinyl to CD. Have A receiver (Pioneer) and turntable (JVC) connected to sound card. I recorded 80 or so albums with this config. Now all of a sudden, I can't record. It's like the sound card isn't recognizing the signal. (Phase scope just sits there). I can playback anything that's on the computer OK and even re-record (phase scope still doesn't work tho.)It's like something is on mute or a line-in isn't being recognized. Device Manager says everything is working properly, but its not. Any suggestions?
