Usually, the default alsa audio device go through pulse audio on a system using pulseaudio. Try to use "alsa:default" as the audio device in SvxLink instead of plughw. You may also have a "pulse" alsa audio device. You can list alsa audio devices using "aplay -L". If that works but is the wrong hardware device, you will need to do some Alsa config hacking. I have no idea how to set up a pulse alsa device which points to another hardware device. You'll need to google on this I guess or if someone on the list knows. A hint is that you need to set something up in the ".asoundrc" file in your home directory. 73's de SM0SVX / Tobias > > > $ rpm -qa | grep -i -e audio -e alsa | sort > > alsa-lib-1.0.22-3.el6.i686 > alsa-lib-1.0.22-3.el6.x86_64 > alsa-lib-devel-1.0.22-3.el6.x86_64 > alsa-plugins-pulseaudio-1.0.21-3.el6.x86_64 > alsa-utils-1.0.22-5.el6.x86_64 > audiofile-0.2.6-11.1.el6.x86_64 > audiofile-devel-0.2.6-11.1.el6.x86_64 > jack-audio-connection-kit-0.118.0-1.el6.x86_64 > jack-audio-connection-kit-devel-0.118.0-1.el6.x86_64 > kde-settings-pulseaudio-4.3.1-1.el6.centos.noarch > kmod-alsa-1.0.25-4.el6.elrepo.x86_64 > libcdaudio-0.99.12p2-13.el6.x86_64 > portaudio-19-20120117.el6.x86_64 > portaudio-devel-19-20120117.el6.x86_64 > pulseaudio-0.9.21-14.el6_3.x86_64 > pulseaudio-gdm-hooks-0.9.21-14.el6_3.x86_64 > pulseaudio-libs-0.9.21-14.el6_3.x86_64 > pulseaudio-libs-devel-0.9.21-14.el6_3.x86_64 > pulseaudio-libs-glib2-0.9.21-14.el6_3.x86_64 > pulseaudio-libs-zeroconf-0.9.21-14.el6_3.x86_64 > pulseaudio-module-bluetooth-0.9.21-14.el6_3.x86_64 > pulseaudio-module-gconf-0.9.21-14.el6_3.x86_64 > pulseaudio-module-x11-0.9.21-14.el6_3.x86_64 > pulseaudio-utils-0.9.21-14.el6_3.x86_64 > > > --David > > ------------------------------------------------------------------------------ > Everyone hates slow websites.
