I was having issues with sound once uploaded to GoDaddy on a test project. I found the solution and I think this will be helpful to others exporting on the native HTML5 Website settings.
Create a web.config and put it in in the same directory as your index.html
Here is what the contents of the file should look like when using IIS:
<configuration>
<system.webServer>
<staticContent>
<remove fileExtension=".ogg" />
<mimeMap fileExtension=".EXTENSION" mimeType="application/ogg" />
<remove fileExtension=".ogv" />
<mimeMap fileExtension=".EXTENSION" mimeType="video/ogg" />
<remove fileExtension=".oga" />
<mimeMap fileExtension=".EXTENSION" mimeType="audio/ogg" />
</staticContent>
</system.webServer>
</configuration>
Here is what it would looke like in Apache using the .htacess file instead of web.config:
Most servers (including those used by GoDaddy) by default don?t serve the appropriate MIME Types for OGG files. That being the case, you?ll need set the appropriate MIME Types for OGG files if you want HTML5 audio players to work correctly in Firefox. So for an Apache server, you would need to add the following to your .htaccess file:
AddType audio/ogg .oga
AddType video/ogg .ogv
AddType application/ogg .ogg
