We got a report that the audio search results were not accessible with JAWS 14.137 screen reader software. The google chrome accessibility page lists JAWS and NVDA. Downloaded and tested both. Found JAWS 14.0 working perfectly fine with our audio search page, with Firefox and Chrome. Also with IE8 (on my machine which has Win XP, highest version of Internet Explorer is IE8). Also fine on NVDA, which is free, as against JAWS which is $1000. Probably reasons, some of which I also faced:
1. Opening the page in a new tab instead of a new window causes problems. Open all pages in new windows instead.
2. Using old version of browser may cause issues on radiosai.org - upgrade to latest version of browser.
