I usually like to think that I'm not here to be expert, but to rise
experts. So, please, keep
questions coming.

What you would do in local.conf is:

PACKAGECONFIG_pn-sox = "alsa"
PACKAGECONFIG_pn-sox += "wavpack"

in case you want to add alsa AND wavpack (I really have no idea if
this selection makes sense together)


But, from sox_14.4.0.bb file you can see:


PACKAGECONFIG ??= "${@base_contains('DISTRO_FEATURES', 'pulseaudio',
'pulseaudio', '', d)} \
                   ${@base_contains('DISTRO_FEATURES', 'alsa', 'alsa', '', d)} \
                   magic \
"

So, PACKAGECONFIG will be automatica filled (if you don't on
local.conf) based on DISTRO_FEATURES.

At least for pulseaudio, and alsa support.

So, I think it makes sense to you avoid pulseaudio, remove it from
DISTRO_FEATURES. But it will affect your whole system.
