Our company has an online training video (powered through Cornerstone) that is unable to play sound when first loaded. The sound icon embedded in the video is turned off by default. We have to manually turn the icon on and then the sound works. If closing the browser and reopening the training video, the sound is once again turned off. This seems to randomly be occurring on different machines, including my own.
I've tested several other test machines, and the sound is enabled from the beginning and works without problem.
This only occurs in Internet Explorer v11, our company's default browser. It works fine on Chrome and Firefox.
I've tried different Dell laptop models and Windows OS (7, 1607, 1709) versions, can't find a pattern.
I've tried the following so far:
a. Added website to compatibility view, no change.
b. Deleted all browsing history, no change.
c. Reset IE settings/Deleted personal settings, no change.
d. Website domain is added as a Trusted Site in IE.
e. Checked the following registry key…HKCU\Software\Microsoft\Internet Explorer\Main; PlaySounds was set to 0, I set it to 1, no change.
f. I imported the Main registry keys from a PC where the audio works, onto my PC, no change.
g. IE > Tools > Active X Filtering is turned off.
h. Uninstalled audio driver, tried both generic and model specific drivers.
i. Deleted Flash player browsing data and settings.
j. Ran IE v11 with all add-ins disabled.
Not sure where else to look. Thoughts?
