Opera 45 no mp3 play inside Sandbox [CLOSED - DUPLICATE]

[Urlipurz]

Hi,
When i try to play mp3 files inside a website nothing happens.
(e.g. "http://deit.dict.cc/?s=hallo" or "http://www.book2.nl/book2/IT/SOUND/0764 ... cedownload")
Outside sandbox no problem.
IE no problem.
Firefox no problem.
Opera 43.xxx no problem.

Tried on different systems:
Win7 Ultimate 32bit
Win10 Home 32bit

Hello Urlipurz,

I tested and reproduced the issue, it also happens in 64 bit versions.
I'll make the devs aware.

I'll update this thread with any new information (whenever it becomes available).

Regards,

Yesterday I rechecked a bunch of Opera browser versions after 44.0.2510.1449 and up to the current Opera release - 49.0.2725.56.
None of these versions of the Opera browser when running through Sandboxie does not work streaming audio on music sites,
such as:

www.beatport.com
music.yandex.ru
and so on (actually on any such sites!)

Once again, I note that the latest version of the Opera browser, which reproduces streaming audio on music sites without any problems when Opera itself is launched in Sanndboxie,
is the version of Opera 44.0.2510.1449.

But the most interesting is that. that without Sandboxie absolutely any version of Opera browser perfectly reproduces streaming audio on any music sites, which makes it absolutely possible to draw a conclusion about the problem in Sandboxie.
Dear Sandboxie developers, I understand that Chrome and Firefox are the priority for you, but please optimize Sandboxie's work with the latest versions of Opera browser when playing streaming audio on music sites.

Thank you!

It's not just the version, it's a particular setting flag that must be disabled (opera://flags/#media-windows-mf-demuxer) that can bypass the problem. I was able to play the audio with no problem up to version 48 with the setting turned off. Version 49 removed the setting and I verified it won't play with version 49. For now I am using 48 and have disabled Opera updating. Hopefully Sandboxie will fix this soon.
