No transaction sound on Android in Chrome

[mweinelt]

Since roughly 6-8 weeks we don't hear any transaction sound anymore on our Android 7.1 tablets using Chrome's "Add to Desktop" feature. Both are running Chrome 66.0.3359.158.

I can also confirm that on my N5X with 8.1 and the same Chrome version.

I checked that Chrome lets the page play audio in general, but there is none. I can see the webpage requests the ogg file just fine:

Hi! Google added a feature to disable auto play of audio in chrome. They're already fixing that bug - but you can workaround that issue if you set "Autoplay policy" to "No user gesture required" in chrome://flags/

Awesome, that was it.
