Thanks for the problem report.
This was introduced by sox.sf.net commit 61428b3
"Clean up lsx_malloc() and friends" which Debian
imported as a "fix" to CVE-2019-8355.
It's caused by lsx_strdup() being called with a NULL pointer
from src/sox.c line 2370
```
norm_level = lsx_strdup(optstate.arg);

Your file is actually an Opus file in an Ogg container. Unfortunately
Debian (and hence Ubuntu) compiles the Opus format handler if
libopusfile-dev in installed but fails to create a libsox-fmt-opus
package from it.
The required patch to the debian source package is at
