Captivate 9 audio handling

Hi,

we produced a course with Captivate 9 as responsive HTML5 output. So far, it works fine on a PC. However, we would like to run it as well on a Linix terminal with Chromium browser. The course works there as well, only the audio is not working yet. Some functions of Chromium have been disabled. With the current settings and functions, audio played within a "normal" HTML5-website works. Only with the Captivate output there is no sound.

Can anyone of you tell me how Captivate handles audio in a browser and which functions need to be enabled in Chromium for this purpose? This would be very helpful.

Kind regards,

Kerstin
