I run DVD 19 but my PC is out of action so I'm using my laptop with 17. In both cases I run out digitally to an external DAC. I was watchin a film this evening went out of the room and the sound stopped, I returned to see there was sound but it had switched over to the laptops audio. Everything else bar cyberlink 17 works fine going through the dac and external sound system. The other odd thing is 17 has now lost its volume control. I've been tow hours trying to get a fffing ticket and it willnot accept my query. What atotal waste of time some of these sofware companies are. In desperation I came here. so if anyone has any ideas I'd be grateful. I've tried the wasapi out to no avail Thanks
If your DAC cannot decode dolby or dts audio itself (has no dolby or dts decoders), deselect the dolby and dta options of your DAC in Windows sound settings > Playback devices > Properties (of your DAC) > Supported format.
Then, try the playback in powerdvd.
The dolby or dts decoders are usually in home cinema amplifier. Most of "DAC" devices don't have the decoders at all natively.
The decoder license is pricey.
