Can any sound experts out there help me with this issue? I have a show playlist on a Kindle, which I patch into a Fender Passport Conference amp system. All my music tracks are Mp3, and all play well on the Kindle (and on Windows Media Player for that matter). The strange thing is that some of them will not play properly through the amplifier. Not only is the volume abnormally low, the sound is muffled and I also hear noises in the background that sound like a distant parakeet chirping. Those tracks that I downloaded directly from the internet work well. The problem is with tracks that I recorded myself from the internet using a program called Total Recorder. So you would think there is a problem in the way I recorded them, right? Except that THE TRACKS PLAY FINE ON THE KINDLE -- BUT THEY MANIFEST THE PROBLEMS LISTED ABOVE ONLY WHEN I TRY TO PLAY THEM THROUGH THE AMP. Does anyone know why that would be? Thanks.

UPDATE: I just paid for and downloaded another Mp3 file -- it plays perfectly on the Kindle but when I try to play it through the Amp it has the same sound issues I described above. So the problem is not just with songs I record myself; the problem also exists for songs I download.

It could be your cable or conenction to the amp/system. Have you tried another cable or are you using the proepr cable(s)?

Mindpro, there can't be a problem with the cable because other songs that I play from the same playlist, using the same equipment, play just fine.

Are you sure your input/component can play both/all formats?

All songs on the playlist are Mp3 files, unless there is some subtle technical difference I don't know about.

And, again, it is SO bizarre that some of the songs play fine on the Kindle itself, but not through the amp. Others play fine both on the Kindle and through the amp, using the same cable.

There seems to be a signal problem of some type. Are some tracks/songs older format files or versions and those not playing a newer format or Mp3?

I'm not sure how I would tell that. As I said, they are all Mp3. But, yes, there must be some kind of signal problem with a few of the tracks.

Not alll MP3 files are created equal, James. For example, bitrates and sample rates can be different, and that has the potential to present compatibility problems in some file players. It’s also possible that some of your files are corrupted.

I suggest three things. Try re-downloading the audio files from wherever you bought them.

Another is to try other mp3 files players to see if any work with all your files.

The other is to use any mp3 converter/creator, and use exactly the same settings for one of your files that works and one that does not, and then see if they both play correctly. If so, convert ALL of you mp3 files in exactly the same way. Just be aware that every mp3 conversion adds degradation. In a room full of magic fans, probably no one will notice.

Good luck!
