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 Jan 27 15:28:41 skype kernel: [ 3984.318403] snd-dummy skypiax driver, /usr/src/alsa-driver-1.0.20/drivers/../alsa-kernel/drivers/dummy.c:920 working on a machine with 250HZ kernel Jan 27 15:28:50 skype kernel: [ 3994.795786] process `skype' is using obsolete setsockopt SO_BSDCOMPAT Jan 27 15:28:56 skype kernel: [ 4005.289907] __ratelimit: 490 messages suppressed Jan 27 15:29:01 skype kernel: [ 4012.458310] process `skype' is using obsolete setsockopt SO_BSDCOMPAT Jan 27 15:29:01 skype kernel: [ 4013.326290] __ratelimit: 499 messages suppressed 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
