 Please show your
 - dmesg
 - audiocfg list
 - sysctl hw.audio*
 
 Please describe details what you did (for example, about keybind
 and mixerctl configuration) and how to reproduce.
 Since when has the problem existed?

 If "Changing the audio latency" means "sysctl -w hw.audio*.blk_ms",
 it looks strange to me.  When the blk_ms can be changed, there
 should be no audio tracks.  Therefore, audio layer doesn't make
 sound at that point.

 Just to confirm, are these messages and the reported problem
 synchronized?
 
 Thanks,
