MediaMonkey 2.5.5.996/997 had a bug which overwrote the first 4

bytes in a flac header during tagging operations. The impact of the bug

is that SampleRate and bitrate Rate info is lost lost from the header,

causing playback problems on other players and devices.



This issue was fixed in version 2.5.5.998. To prevent the problem from

occuring, upgrade to the current version of MediaMonkey.



If this problem affects tracks in your library, a flacfix tool

http://www.mediamonkey.com/beta/FlacFixTool.zip has been created

that tries to recreate header data in the first audio frame. In cases

where the buggy tagging occured only once, the 4-byte header can be

recreated so that the flac file is exactly as it was when it was originally

ripped. However, if the file was tagged several times by the faulty

version of MediaMonkey, it is impossible to recover the tag. To use the

tool:

1) extract the zip file to /Program Files/MediaMonkey/Scripts/Auto folder

    and restart MediaMonkey.

2) select all your flac tracks, and select Tools > Check and fix flac

    corruption.

    MediaMonkey will check the integrity of your flac tracks, and attempt to

    repair those that have been compromised.

3) After the tool has been run, download audiotester at

    http://www.vuplayer.com/files/audiotester.zip and have it verify all

    your FLAC files. It will report any files that are still damaged.

    For tracks reported as damaged, there are 2 options:

    o Convert the FLAC files to FLAC using the current version of

       MediaMonkey. This will re-encode the files without the first (corrupted)

       frame, but will consequently lose the first few ms of audio data (this is

       usually silence).

    o Rerip the CDs. This is often the preferred approach if you need your

       flac files to be lossless replicas of the original CD, however, it can be

       painful as it requires previously entered metadata to be re-entered.
