Just crashes with this panic after a few min of playing.

Do you have any specifics about this issue? Can you reproduce it successfully? The crash is happening from inside of the incoming audio handler, meaning it's triggered by other users talking in the channel.

[Caindrac]

It is a not a problem to reproduce it happens every time I turn on the bot. It has happened both after starting a song as well as just sitting afk for a 1-2 minutes.

It has happened both after starting a song as well as just sitting afk for a 1-2 minutes.

But were any users on the server talking? What versions of Mumble are the talking users using?

[Caindrac]

Yes there where people talking I don't have the information on my on what version they are using.

[matthieugrieger]

You can check what version they are using by right-clicking on them and selecting "Information". They do have to be online, however.
