I found this site because I have been aware of this issue for years, and was curious if anyone had a work-around. Not looking good so far, but this is good to know.

This is only one of the millions of issues Flash has. I hate coding for it… if I have to make another flash game, I'm jumping out the window.

This bug remains in flash player10 for IE, but in FireFox it works fine.

I know I'm late to the post-a-comment party, but thank you so much Steven (and Heather) for your information on this. I was seriously ready to put my head through a wall over this one. Sounds like it's time to pony up for cs4.

FYI — I just installed the beta (RC) for FlashPlayer 10 and this bug appears to be fixed! All of my clips — no matter what the bitrate — pause/play and scrub perfectly…

Thanks Steven. I'm also amazed that Adobe let this one get by. When flash is being used to power 95% of the media players on the web, you can't punt on this kind of thing up.

I ran into this major bug a while ago. If I remember well, related to the sample rate, and the position you get is something like:
position * {sample_rate}/ 44100.

Very helpful.
I had 32kbps clips and was struggling to find out why pause was not working. Incedentally – if you hardcode the Sound.play(startposition) start position to something like 5 seconds… and your song is a minute (60 seconds)… it will resume playing at 5 seconds and will stop at 55 seconds… 5 seconds from the end. In other words it ill come up startseconds short. This has something to do with the bug I'm sure.

Lastly – somewhat related is that if you're trying to get ID3 tags Event.ID3 to fire… make sure your mp3 files have id3v1.1, or id3v2.3 or better. iTunes had my tags at 2.2 and they were not recognized by AS3.

Hope this helps.

THANK YOU! I have wasted the better part of my day trying to figure out why two mp3s were messing up in my player.

IMPORTANT! In addition to the 128kbps, the mp3 file must be sampled @ 44.100kHz. Anything higher messes it up as well.

Cheers!

Thanks for posting this. I'm just learning AS3, and just discovered this this morning – well, I discovered that it wasn't working as advertised, but I never would have figured this out – so, thanks. Even after matt (above) said this was already in Adobe's bug database, I had trouble finding it – I guess known issues don't make it into the "Knowledge Base" until there is a known fix or work-around.

Anyway, here is an additional detail – maybe it will make more sense to you as to why this should be: during my testing I discovered that if I imported the audio file into the library first – i.e. at author time – instead of loading the sound from an external file at run time, that my play/pause buttons now worked fine!

I know better than to use a VBR.

By now, I would hope that the Flash community knows the Flash player does not get along well with VBRs. That's a different issue than this, and one that Macromedia/Adobe has never addressed.
