[Pianod] Home directory not accessible: Permission denied

[Perette Barella]

Any chance you’ve got libao configured to use Pulse Audio as an output?  Instances of that particular message suggest it’s the likely culprit.

If you are, then...
I’m guessing that the libao/PA code tries to read a config file in the home directory when the audio device is opened (not at libao initialization)… and by then pianod has already dropped root privs.

Maybe set the HOME environment variable (see Gary Koch’s post), make sure that directory is a+x so ‘nobody’ can access its files, and make sure the Pulse Audio config file (if it exists) is a+r so ‘nobody’ can read it.
