Can't play music online
I am using Vivaldi for Windows. When i play music at http://nhaccuatui.com, i cant play music. Please check the error and fix it! Example: http://www.nhaccuatui.com/bai-hat/tam-su-voi-nguoi-la-tien-cookie.H8GqrTEErwJR.html
Music plays for me. Maybe check if the volume is up.
In any case it's flash, make sure you got flash installed too.
Plays with Vivaldi 1.0.365.3 (32bit) on Windows 10 (x64)
The Audio is a MP3.
Which Windows do you use?
