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?
