Having looked at lots and lots of digital FDR data over the years (most for incidents, not accidents), it does take some time to make sense of the data. Data corruption is not uncommon, nor is valid but 'miscaled' data (e.g. off by a factor of 2 or 4, that sort of thing), and things like power transfers or momentary power interrupts can corrupt data for several seconds.
Actual CVR recordings are seldom (never?) released after a fatal accident - only a transcript will be released to the public, and that's not likely to be real soon. I listened to one CVR when I was actively involved in an investigation (there was a 'click' that they wanted my opinion of what the sound was). Let's just say that listening to doomed pilots last words is not pleasant.
There will undoubtedly be complaints that more information is not forthcoming over the next several weeks. That's by design - during an active investigation the participants are effectively under a gag order. Unauthorized release of information can be career limiting - all data release is to be from the investigating authority. Sure, there'll be some leaks, but much of it may well be wrong (or at least inaccurate), which is why all the information is supposed to be released through channels.
So cool it with all the conspiracy theories for a while. The information will be released in due time.
