Hi, I have just loaded my ulead videostudio 10 plus onto my new computer and am having the exact same problem you have outlined. The sound system on my computer is the same as yours - Realtek HD Audio - sound is working fine in all other programs but no sound is coming thru in this program.
Have you managed to solve the problem or do you think the videostudio10 is just not compatible with WINDOWS 7?
If anyone can offer any help I’d be very grateful…
[QUOTE=secretcodebreaker;2180108]I just installed Ulead VideoStudio 10 SE (Corel Corp).
It seems to be working OK, except there is no sound when it plays a video clip (Edit Mode).
I’ve tested my sound system (Realtek HD Audio) and it works fine.
I’ve played the clip(s) (MPEG2) using Media Player and WinDVD Player and the sound is fine.
I tried changing the volume controls shown on the scene although the default appears to be 100% of normal.
If I had to guess, I’d say that the audio portion of the program is not outputting (connected?) to the PC sound system.
However, if I select the Audio view of the clip the red line is flat which indicates to me that the program is not decoding the audio portion of the video clip (MPEG2 file).
I don’t have a clue as to what I should do, since this is the first time I have tried to use this program.[/QUOTE]
