How does your patch solve this?

I don’t think anything like that is needed: $ALSA_PLUGINS_DIR is read by
alsa-lib, which allows it to find ALSA plug-ins, even those installed in
the user environment.  That’s all we need, right?

(It’s the same pattern as $AC_LOCAL_PATH, $LOCALE_ARCHIVE, etc.)

On IRC I was talking about fixing ‘alsamixer’, ‘amixer’, etc. so that
they too would honor $ALSA_PLUGINS_DIR.  I don’t understand why they
don’t currently.

Thanks,
Ludo’.
