DM800 HD no sound after power outage

Hi. Yesterday we had a power outage during the night and in the evening when we wanted to watch the news we recognized that there was no sound at all. I have a DM800 HD Dreambox and was anxious that the power outage destroyed the sound card or another hardware component regarding sound (cable, HDMI…). So I checked all possible connections and cables, did a reboot of the DM800 but the state remained the same. After searching a few blog entries on the net I found a recommendation to shutdown the DM800 HD and leave it away from power for approx. 5 minutes and afterwards power it up again. Know what? It worked as a charm. It seems that the box looses connection to the sound processing daemon somehow and stores that over a reboot too. Everything fine again.
