The settings of /dev/audioN (or /dev/soundN) are those of a "virtual"
device.

The output of 'audiocfg list' shows the possible settings of the
hardware instead. The data is converted on the fly from and to
the "virtual" settings.

With 'audioconfig set' you can change the hardware settings
(within the limits of what the hardware driver supports).

If hardware and "virtual" device have the same settings, there
is no conversion done.

N.B. when resampling takes place, the conversion has a rather
low quality, in particular when the signal hasn't passed a
reasonable filter. But I don't know how much that affects
your decoder.
