Hi,

Applications must close their handles upon detecting failures, like detach.
Else device numbers will be used up pretty quickly.

This is a known issue.

One solution is perhaps to use audio/virtual_oss, which proxy access to
/dev/dsp and possibly in the future /dev/mixer aswell, so that these FreeBSD
specific artifacts are hidden.
