Is my EDIROL product compatible with the Microsoft Windows Vista(TM)?

In Windows, the Speaker icon in the Task Bar disappeared after I installed the driverfor the UA-1EX. Why is this?

When I input an analog signal to the UA-1EX's INPUT or MIC jacks, can I hear this audio from the digital output in real time?

Can I record the sounds coming from my computer (such as Internet radio) into my computer recording software using the UA-1EX?

During audio recording, can I adjust the input volume on the UA-1EX?

While I record the digital audio signal arriving at the UA-1EX's DIGITAL INPUT jack to my computer, can I also monitor the audio coming from the computer?

Is the UA-1EX's MIC input monaural or stereo?

I've connected a digital device to the UA-1EX and recorded some audio from the device into recording software on my computer. However, when I play back the recorded audio, the playback speed and pitch is different from the original audio. Why is this?
