The captcha audio functionality will be available in iOS mobile devices.
Sorry - I believe this may be a local issue and not the control
Hi Nik, Any update on integration in the latest software updates? We are seeing reports that it remains broken for iOS devices.
We managed to track down the problem that caused the missing audio in iOS. It turns out that a WAVE resource is not considered a correct media resource unless the web server has set the Accept-Ranges: bytes HTTP Response header. Once the header is in place, the audio starts playing. We will incorporate this header in our Captcha Audio handler. However in the mean time you could make sure this header is added to the response. A possible approach could be using an HttpModule. Attached is a sample implementation.
40 million iOS devices plus million more iMacs/Macbooks, and uncountable users and regulations that require accessibility. I hope to see this critical fix soon. We estimate less than a day's work to add a readystate check to RadCAPTCHA to resolve the issue.
