This points to an issue with your alsa configuration/installation.

Same error as above, a problem with alsa.

Not quite sure what the error is, perhaps you need to run mpg321
verbosely.

Just shooting randomly in the dark here:
* Did you update alsa recently? Do you have old alsa pcm
configurations files from before? Maybe those files are screwing
