I also have an issue with the sound not playing (sorry if this is not the right post for it). Running windows 10 2 pc setup with avermedia c985. Im using the audio in portion of the avermedia opposed to using the hdmi method for sound. Since the new update 0.12.0 im now not able to get any of my in game audio to the stream. The previous version, i did not have an issue. For what its worth i went to the avermedia program and made sure the settings were set proper. Upon further inspection i noticed that is shows sound playing through that program just fine but now when i go to obs i get nothing. I have separated each sound ie: one track for my music,one track for game, and the last track for my microphone. Mic and music work fine but game sound will not work in stream.
Since i did the install through the program itself because it prompted me to, my settings seemed to have not altered and stayed the same throughout my scene i created. Lastly im not sure if this has anything to do with it but now when i have to capture my game before i would select LGHD stream engine(just like old obs and the last version of obs mp). Now i can't use that as it will show up but stay static and frozen. Im now having to use the c985 bus 2 to get it to stream. It streams fine like that but again now no sound where is when i had LGHD stream engine it was producing sound. Any thoughts?
Final note i made sure under my video capture (c985 bus 2) that use custom audio device is checked and lghd stream engine audio is used under that setting(the audio in on the avermedia at least before it was), just like i had it with the previous version of obs mp, with the difference now being which decoder i have to select. Previous OBS and OBS MP was LGHD Streaming engine now only c985 bus will work for the video portion. Not sure if this is a bug or if its on my end ;(
