[Freeswitch-users] mod_skypiax - help needed with modified snd-dummy (one way audio)

[Giovanni Maruzzelli]

I don't think you got two snd-dummy loaded (but maybe yes)
what's the output of:

aplay -l

?

If instead you are referring to the choices that skype clients offers
you in the "set audio devices" window, choose Dummy PCM (hw0:0)

Eg: not the "default", but the "hardware" one
