You should “Mixdown” the Audio for playback before you dub out of FCP, or during the edit, if you have audio/video stuttering, drop-outs, sync-slippage, or freezes.
NOTE: Mixdown has even been demonstrated to help with slipping, skipping problems (or “missing” audio clips) for files being EXPORTED as QT (or similar) files out of FCP.
First, SELECT ALL of your audio tracks (highlight them) on the timeline, then:
Sequence Menu > Render Only > Mixdown.
You should see a dialog box telling you its rendering.
It might seem to make little sense that “Mixing down” even simple audio tracks will “fix” complex video “freezes” or random audio dropouts to tape or export, but it CAN.
NOTE: It does not matter of you only have one audio track, if there are random freezes during output, you should try the Mixdown.

Try looking here:

This seems to be the answer to many of these kind of problems.

You will not see any colored bars on the timeline regarding “Audio Mixdown.”
However, you should remember to “Mixdown” the Audio for playback before you dub out of FCP, or during the edit, if you have audio/video stuttering, drop-outs, sync-slippage, or freezes.

[tmacdonald] “But if I am outputting to the web, how would an external monitor help? I should judge the quality on the computer, because everyone else will be viewing it on the computer.”
Because FCP’s Canvas is NOT DESIGNED to give an accurate IMAGE for judging quality.
It’s output is not the same thing as “viewing on the computer”, it is simply “viewing on the CANVAS” (for reference).
After rendering, many images look WORSE on the Canvas than they did “raw.”

“Ditto” all the way to Walter’s post.

[Rafi Bagramian] “Or are you saying it needs a particular type of power?”
Yes.
These tiny mics usually on have a single inner conductor and a wrap-around shield (not two inner conductors like a standard “balanced” mic line.
You must provide DC power with the right current-limiting resistor to operate them, as well as take the audio off of the same inner lead.
This is NOT true of ALL mini mics, but those which are connected by a short cable directly to a wireless transmitter USUALLY are this kind.

You must have a “convertor box” to get the “Phantom Power” coming from the camera (if any) to operate the mics’ internal IC amplifier.
There are some stand-alone (no”Phantom Power” needed) “convertor boxes” that have internal batteries that can power these mics.
The boxes have a standard full-size XLR jack output on them.Contact Sennheiser with the model number of your specific lav mics and ask what they have for you.

You didn’t seem to like like my first answer.
But it still applies. -
You must only judge QUALITY on an external (NTSC or PAL) VIDEO monitor.
You cannot judge quality in the Canvas window on the computer monitor.

You say the clips are “long enough” for the total dissolve length, but if a dissolve is “drag and dropped” it can sometimes be seen as a START-at-cut, END-at-cut, or CENTERED-on-cut effect.
If BOTH the incoming AND/OR outgoing clips do not EACH have enough “handle” in overlaping video, and the dissolve “dropped on” so that it “tries” to use ALL the handle frames from either side of the cut, that can be the problem.
To check, double-click the errant effect into the Viewer window and change its start-point.
