mp3 files

I have macbook with Sierra 10.12.2 and Audacity 2.1.2. I create mp3 files for website with Audacity. Safari browser can load but not play the sound files. Chrome or Firefox have no problem. A friend uses Wavepad to create an mp3 file, I have no problem listening with Safari. Why am I having this problem with Audacity ?

Apparently it’s either a VBR thing or an ID3 thing …

MP3s created with Audacity work OK for me on Sierra.
Do you see 4 players on this page and do they all work?

Yes, they all work. I’ll look into my configuration.

What version of LAME ?

It shouldn’t make any difference, but I’m using LAME 3.99.5 on Debian Linux.

I suspect that the problem is related to how the MP3 is embedded in the page.
Here’s an example of the HTML code that I used:

<audio src="cbr128-no-metadata.mp3" controls="controls" preload="auto"></audio>
