Question / Help No Audio on Stream/Recording from Media Source

I know there's another thread with people fighting about audio monitoring. This is not the same problem.

I have a bunch of media sources I use - countdown videos, stream pause videos and so on. They play fine, and the audio volume bar for that source shows the audio volume, so I know it's being decoded right... it just doesn't end up in the stream nor in the recorded video. It does seem to *sometimes* work, but most of the time I just get a silent video output to the stream, despite the volume meter dancing.

This hit me when I was doing a 24-hour charity marathon lately, where I ended up having to play the file at the same time in VLC just to get the audio to play, which meant I couldn't use my desktop for anything else while this was going on. It did seem like one of the 4 videos I used worked, because some people complained about double audio on that one. There's nothing technically different between them though.

Things I've checked:
  • The files definitely have audio in them.
  • The media sources are not muted.
  • Volume output for the media source is set to 100%.
  • The audio mixer is set to output audio on all channels for that source.
  • No filters are being applied to the media sources.
It does seem to me like the same video sometimes works and sometimes doesn't. Video playback always works flawlessly, audio comes through like 1 time out of 4 or something. Because the volume meter shows it as working all the time, there's no way for me to tell either without listening to my own stream.

Here's the VOD of the very silent countdown from my charity stream: https://www.twitch.tv/slicedlime/v/100580448 and here's a video of how that looks in OBS Studio: http://www.slicedlime.tv/dl/obs_countdown.m4v. Not sure what other info I could provide, but I'd happily dig something up if it helps.
 
Do certain files always work and other files always not work?

Otherwise I have no idea, but it could be that only some types of media sources work for the audio portion. You'll need to correlate what's going on when it works vs. when it doesn't.
 
Did you ever find a solution to this? I'm having the same issue.

Media source is an mp3, I can hear it in my monitor (set to monitor and output) but it doesnt play on stream. Have made sure it's not muted or filtered and is outputting on channel 1.
