Execution of unit test independent from actual sound device is one of
my intention for the tests, and actually the they performs. Executables
of the test include duplicated code of axfer for this intention. Please
refer to 'axfer/test/Makefile.am'.

The alsa-utils uses GNU Automake to implement test. As long as I know,
any Makefile generated by GNU Automake doesn't run test unless
'check' target is given explicitly.
https://www.gnu.org/software/automake/manual/html_node/Tests.html

Thereore, it depends on yout configuration of debhelper to execute the
tests in building time of deb package. Please recheck your 'debian/rules'
and adds appropriate directives to suppress execution of test for axfer
(perhaps, 'override_dh_auto_test'). For example:

```
override_dh_auto_test:
        true
```

For your information, alsa-utils includes no other test programs.
