[BucherTomas]

@sasank4git The exception complains about audio decoder initialization failed. The audio in your content has sampling frequency of 96000 Hz. I would say that this is the reason for the issues you are experiencing. Resample the audio to more common 48000 or 44100 Hz and try again with Opera. Chrome likely has some internal resampling involved that takes care of this.

[joeyparrish]

There doesn’t seem to be anything we can do to control Opera’s support for audio frequencies, so I’m closing this issue.
