trace:oss of test sound using default device in winecfg

Sometime after Wine 8.11, the OSS driver sends to the device node one higher
than selected.  Whether the "System Default" or the specific node device is
picked in winecfg, the "Test Sound" goes to one higher than chosen.

In my case, the speakers are on /dev/dsp4.  In the log, that device is
considered the default devnode.  However, the devnode chosen for output is
/dev/dsp5.  If I chose /dev/dsp3 specifically, then the audio will be output
via the speakers.

It definitely looks like an off-by-one bug.

Workaround:  select lower device by number
