It means that the plug plugin (that the ALSA lib uses to automatically
convert between sample formats) was not able to find any combination of
format/rate/channels/access that would work with your hardware.
It is possible that some entries in the snd_pcm_hardware struct are set
in an inconsistent way. Please show the code of the driver.

No, when the plug plugin being executed means that the configuration
files for this have been found.
