Description Max Wu 2013-04-04 01:32:39 UTC
If I play 2 videos files.
Then third video will have no sound.
If I pause first or second video, then third video sound will come back.
Music file either.
How can I fix this?

I can reproduce this. There are no errors in the log and all clients appear to be playing fine (they are streaming, not stuck). The bug might be in the mixing code - somehow only the first two streams are getting mixed, and the rest are ignored.

I'll try to fix this.
