I pulled a 1.12.2 version of sound physics that supported gliby's voice chat from one of the issue boards and for the most part the voice chat worked very well with the sound physics aside from one major issue. Every time me or my friend died in game both of our audio would cut from our voices and the voice chat would stop working properly. Thinking it was another mod that brought the effect out I tested it with both of us having sound physics and gliby's voice chat only installed, our voices still cut out. I looked at the log and this error pops up when either of us die.

Error in class 'ChannelLWJGL OpenAL'

It repeats until you do a full restart of the client. Is there any way to fix this? I really like your mod and the aspect of proximity chat.
