I’m not sure about the general error or the apparent lack of filters. Maybe trashing prefs and repairing permissions will help. As for the beeping, that happens when FCP doesn’t like the audio format. Always convert any audio to Linear PCM, 48kHz, 16 or 24 bit in an external editor before bringing it into FCP. You can use,Quicktime Pro, Soundtrack Pro, MPEG Streamclip or any other program that can convert audio.
