Question / Help Mic Problem while streaming...

Namja · Feb 26, 2013

Recently I've been experiencing some Mic. disconnects while streaming with OBS. I use a separate mic [Blue Snowball Mic] to stream so that my viewers can hear me. At the moment, I'm using the v0.437b (test build 5) of OBS to stream. The only way to fix this problem is that I have to end and then restart the stream again.

Any assistance will be gladly appreciated.

By the way... OBS is such a great streaming program and I'm very happy that I was introduced to this and have already promoted this software to others I know :)
[To the creator] Keep up the good work. Will gladly support this great piece of software.

Thanks.
Namja.

To make it easier for people to help you , you should post a logfile from when that issue occurred!

Oops, my bad. I totally forgot about the log.

Thanks

Hm, it doesn't say there was a mic disconnect in the log. Is the mic actually fully disconnected when this happens?

Namja · Feb 28, 2013

Hey Jim,

Nope, the mic is still physically connected. It's just within OBS of how it has the appearance of showing the mic is muted w/o the muted mic icon on the OBS dashboard.

Luckily, I streamed about 9+ hrs today and had no issues/disconnects of the mic so far and this is from using the latest test build [test build 6]. So I'm not sure if this actual test build resolved my issue or again, I just got lucky today and didn't have any disconnects.

Hopefully it won't happen again. Otherwise, I'll keep you updated with my mic issue.

Thanks.
Namja.

Hey Jim,

My mic problem occurred again today while I was streaming. My mic just suddenly disconnects while I'm streaming and in order for it to work again, I have to restart my stream.

Try turning up the "scene buffering time" in advanced to something like 1000. See if that helps at all. Make sure the Mic QPC option is off as well in advanced. If neither work, then you'll have to come by chat or something for some serious debugging.

Namja · Mar 1, 2013

Jim,

Thanks for the quick reply. I'll try to do that tomorrow when I stream again. Hopefully this will resolve the problem.

I'll keep you updated.
