Realtek SoundcardsMost mainstream soundcards provide multiple inputs from which to record (mic, line, aux, etc). Traditionally, the input to be recorded is selected by a control in the soundcard's driver called a "multiplexor" or a "mixer". A multiplexor allows for recording through only one input at a time, while a mixer allows more than one input to be active if desired. Wave Repair is aware of these strategies, and it interfaces with multiplexors and mixers to allow direct selection of recording input and adjustment of recording level.
The drivers for many Realtek-based soundcards operate differently. Rather than allowing one or more inputs to be activated for recording, they instead record from all inputs simultaneously and allow for specific inputs to be switched off if not wanted. So rather than having a multiplexor or mixer control, they instead have multiple "mute" controls. It is this different strategy that Wave Repair currently does not recognise. I am aware of this situation and hope to add the Realtek strategy in a future release.
The upshot of this is that for the time being, while Wave Repair will happily record whatever signal is being supplied throught a Realtek soundcard, it cannot provide the facility to select the input and adjust the level. You will have to use the Windows Volume Control utility instead. This utility is invoked via Start > Programs > Accessories > Entertainment > Volume Control. (There is often a shortcut in the system tray; the icon looks like a loudspeaker cone).
When Volume Control first starts up, it shows the controls for playback, not recording. You will need to switch to the recording controls via Options > Properties.
So, if you see this warning screen pop up:
Before emailing me for advice, check if you have a Realtek soundcard. If you have, then there is no need to advise me of your problem: it is almost certainly what is described above.
