Hi,
I havent checked my site in some time, audio has never been an issue in the past. I updated my site, had audio issues before and after the update. As you can see I have the sample images mixed in.
The Audio files have not been changed, they are all .mp3 and the same as before. I have adjusted the themes to see if that was the issue, all the themes show the same in the top right "Audio Player" then below it "1. Undefined"
my site is http://www.danturano.com is the audio working on your end?
Any help is greatly appreciated.
