Helo muki, Couple of question (sorry if they seems dumb) a. Did you checked the master volume in the tablet? ( canola cannot sets the master volume device, and if the volume is zero or sometimes if the volume in the media player is zero this can influentiate canola) so make sure both volumes are in maximum b. Did you reboot the system (without being plugged on power) before installing ( just to make sure all the services are started correctly) if it was first time installing canola... theres no need to do so. UPNP : is already in final testing, it's a third party pluggin that we are adappting to canola, we plan to release in the next big, feature based update Marcelo
