For some time I am working on a version of my Frederiksborg Museum tour with a Narrator added to almost all panoramas
There are 63 soundfiles which are 1-2 mb.
I got everything working fine until I tested it on my old Galaxy Note 2 with Firefox. (Firefox updated to lastversion)
The sounds did not start at all or they take 30 - 50 sec to load before starting.
I was almost giving up when I got the idea of changing playsound to streamsound.
The result was fantastic. Now sound starts in a sec.
I have been searching the Forum several times for the problems with Android Firefox sound but never seen this solution mentioned.
The problems with Firefox sound and videos on mobiles has been ther for many years.
