Comment 1

[dylankil]

Any word on this? We've an automation test on a remote machine that's blocked due to this bug.

Comment 2

[Blake Wu [:bwu][:blakewu]]

Alfredo,
Can you help check it?

Comment 3

[Alfredo Yang (:alfredo)]

Attachment: audio.mpg

Decoded audio mpeg from base64 data.

Comment 4

[Alfredo Yang (:alfredo)]

I could play the audio stream with FF 57.0.1 on Windows and 59.0a1 on Mac. I'll try base64 encoded way later.

Comment 5

[Alfredo Yang (:alfredo)]

Attachment: audio_base64.htm

Comment 6

[Alfredo Yang (:alfredo)]

I can't reproduce the problem with the base64 encoded audio stream. Could you please provide a link to reproduce it if possible? Thanks.

Comment 7

[dylankil]

This issue only occurs on Remote Desktop Connections. Please RAS in to any Windows Machine, open Firefox and try to play any HTML 5 Audio with a Base64 encoded data URI

Thanks, I could reproduce it. It looks like audio library fails to initialize in remote desktop, so all the audio can't be outputted, not just this file.

[Ralph Giles (:rillian)]

Thanks for the report. This is a known issue, and unfortunate side effect of security restrictions on the content process. We expect it to be resolved by the AudioIPC work in bug 1432303. The fix is targeted for release in June or August.

Comment 10

[Matthew Gregan [:kinetik]]

A temporary workaround (mentioned in bug 1385207 comment 14) is to lower the content sandbox level by visiting about:config and setting security.sandbox.content.level to 2.
