[QUOTE="alexirion, post: 759021, member: 101977"] Hi! I just setup a looping test, that wakes up my computer, starts TV for some seconds and then hibernates the system. I did this to stress test if the TV card has tuner losses after resume from hibernate. Now, I have the behaviour, that sometimes HDMI sound to the connected receiver does not work. This happens about one time per 10 lifetime cycles, or so. In the faulty case, the ATI HDMI sound device is still shown as connected in the device manager, TV is playing, but the receiver don't shows any incoming data and hence is silent. If it happens, also the test sound output from Windows sound device does not work anymore. After deactivating the ATI graphic card and activating it again sound is repaired. The same, when hibernated and resumed. Does someone has similiar problems? Any workarounds, like temporary deactivating sound per script after resume from hibernate? Currently, I'm testing different older ATI driver versions. --Alex [/QUOTE]
