Answer 1

From livedocs :

"Flash can import 8- or 16-bit sounds with a sampling frequency of 11, 22 or 44 kHz. Sounds recorded in formats that are not a multiple of 11 kHz (for example, 8, 32 or 96 kHz) are reprogrammed when imported into Flash. Flash can Convert sounds to reduce sample rates when exporting. "

Flex Builder will not do this for you, so before using it, you need to compress the "music.mp3" file to 22 kHz.

Edit: I cannot find the correct documentation, but it says here :

"Sound sampling rate - measured in Hz, this is recorded when the sound file is recorded for the first time, and Flash.SWF files allow only four speeds.

Flash SWF format has a sampling rate:

5500 Hz

11025 Hz

22050 Hz

44100 Hz (preferred setting) "

You can remove the ID3v2 tag and it should work. I think this is APIC. So anyone who encounters problems embedding MP3 files downloads ID3 Remover: http://sourceforge.net/projects/id3remover/files/id3remover/v1.2/ID3Remover_1_2.zip/download .
