steps:
-Launch PD11
-Open Windows Explorer
-Select VIDEO_TS folder (or mainfolder, usually name of the film) on harddisk
-Drag on PD11
-Movie starts to play
No sound, retry, retry, other movie, same problem, no sound.

-Launch PD10
do the same as above
-movie starts to play, with sound, same movie.

Go into settings, audio, there I see (Current system setting) (x speakers).
That looked/looks fine, but .. still no sound.

From another thread (See "Re:Output: No Information") I see that users have
to select the number of speakers, i.e. change from (Current System Setting) to 2, 4 or more speakers.
I did that.
Waow, sound !!

Seems to me that this should be improved.
If there was no forum, I would never found out.

Thanks to the threadstarter!
