I'm happy for a concern to be raised.

Can you clarify, which environment variable?

I wasn't aware it was possible to override asoundrc with an environment 
variable, until I looked up just now and found ALSA_CONFIG_PATH in the 
code.

Though I do have vague recollection of trying this some years ago. I think 
perhaps I ad issues using it to read other config files. I will re-visit 
when I have time.

FYI To solve my development work, I have:

  ~/.asoundrc      --  my personal settings
  ~/.asoundrc-xxx  --  host specific settings

and I must read both, in that order.
