Description SF 2018-08-02 12:45:08 UTC 
Increasing volume past some limits always results within the error-message:

oss audio output error: cannot write samples: Invalid argument

This error-messages loops and requires restarting the computer, this happens within all programs which output sound.

Seen with 2 different kinds of soundblaster-cards and onboard-sound.

Lots of possible EINVAL sources in dev/sound.

What program is producing the output?  What would be helpful is a truss log of specific syscalls being invoked, with their parameters.  Or even dtrace of the specific stack if you're familiar with how to get that.
