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

[Peter P GMX]

Thanks Giovanni,

I think there may be the problem, that I have 2 sound devices now:
- Dummy PCM (hw0:0) (this is from debian install)
- Dummy PCM Default Audio device (defauzlt: CARD=Dummy) (this is new
since I compiled alsa newly)

I tried both, but both do not work. How do I get rid of the old alsa device?
By the way: I uninstalled Alsa before I installed the new driver
(apt-get remove alsa-utils alsa-base).

Best regards
Peter
