lsof says that metacity has opened the libcanberra[-gtk] library: metacity 18592 brian mem REG 252,2 13772 282544 /usr/lib/libcanberra-gtk.so.0.1.1 metacity 18592 brian mem REG 252,2 59036 279588 /usr/lib/libcanberra.so.0.1.7 metacity 18592 brian mem REG 252,2 13776 317538 /usr/lib/libcanberra-0.15/libcanberra-alsa.so Ah ha. But somebody said "backend" That above looks like metacity/libcanberra are using an ALSA "backend". Let's see what kind of pulse alternative there is... Yup... Just installed "libcanberra-pulse". Let's see how that changes the "user experience". :-) Hrm. A number of apps are using libcanberra and might benefit from being restarted to use the pulse backend: gnome-set 18571 brian mem REG 252,2 13776 317538 /usr/lib/libcanberra-0.15/libcanberra-alsa.so metacity 18592 brian mem REG 252,2 13776 317538 /usr/lib/libcanberra-0.15/libcanberra-alsa.so gnome-vol 18646 brian mem REG 252,2 13776 317538 /usr/lib/libcanberra-0.15/libcanberra-alsa.so Sweet. Restarting metacity seems to have gotten things in better shape: metacity 18945 brian mem REG 252,2 26156 311402 /usr/lib/libcanberra-0.15/libcanberra-pulse.so And even sweeter now... metacity "bell" volume is following the "System Sounds" setting. Nice. Thanx for all the pointers! b.
