Text message in voice chat stops audio file

[fshstk]

since the new text chat in voice channels feature was introduced by discord, typing a message in this chat while trommelbot is playing a track will cause the bot to stop playing.

steps to reproduce:

• play a track using the "herzeigen" command
• while the track is playing, type a message in the voice channel's text chat

expected trommelbot behaviour:

• nothing (keeps playing)

actual behaviour:

• bot stops playing
• bot remains in the channel
• re-trying the herzeigen command will restart the track normally
