Linux Mint 18.2
Firefox 55.0.2 (64-bit)
Flash Player 184.108.40.206
I don't get any sound at c-span.org. On YouTube and other sites I get sound. I saw something about right clicking to select an output when a video is playing. That crashes the flash plug in. Sound plays in Google Chrome and Firefox in Windows 10 on the same machine.
Suspect flashplugin 220.127.116.11 update.
Suggest removal of NPAPI.
Changing a setting in Firefox that I had never previously touched seems to have fixed the problem. I'll have to look on other computers that have worked to stream video from C-SPAN to see if that setting is checked by default in those.
Preferences> Content> check box for Play DRM content
Thanks for the link to the Linux Mint forum where that was suggested.
not_Gaben - Do you mean can multiple sound sources play at the same time? I don't know why I would want to do that. Is it some kind of test of the system? I have an ACER laptop with two little speakers and a headphone jack.
Yeah I was wondering if it works for you.
I am using ubuntu 16.04. Whenever firefox loads a flash game, it blocks the sound in all other applications. For example, I cannot launch the playback of an mp3 file in my music player, or open a youtube video in a new tab, or open a youtube video in chromium. This only happens since the last adobe-flashplugin update. Checking or unchecking the "play DRM content" box doesn't help.
