The problem is that the "pulse" user doesn't have access to the devices under /dev/snd. You need to fix that somehow. There are several ways to do that: - Create an "audio" group (if it doesn't exist yet), then do "chown root:audio /dev/snd/*", and then add the "pulse" user to the "audio" group. - Give the "pulse" user directly access to the devices: "chown pulse:pulse /dev/snd/*". - Give everyone access to the devices: "chmod a+rw /dev/snd/*". -- Tanu
