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

[Peter P GMX]

I have mod_skypiax working nicely so far with 2 Skype channels. Thanks
to all contributors, excellent work!

In order to have more than 8 channels working, I have followed the
instructions in
http://wiki.freeswitch.org/wiki/Skypiax_Skype_Endpoint_and_Trunk
and compiled alsa-driver-1.0.20 with the modified dummy.c file. (System
ist Debian 5.0R3)
It compiled well however when I start snd-dummy I only have
one-way-audio and my logs show

If I reinstall alsa from deb everything sworks fine again (of course
with the current limitations).

First question: Has anybody had this issue before? How can I solve this?

Second question:
As I do not need 64 channels or more: how do I manage, that Skype
instances 9..15 use a second instance of snd-dummy as addressed in the wiki?

Best regards
Peter
