Hi Takashi,
I enumerated all the DELL DisplayPort monitors in our lab and find only two of them being able to produce audible DisplayPort audio...
Thanks for testing!
- DELL 2408WFP
- DELL 2709W
- DELL 3008WFP no CEA extension found
Our monitor here is one of them (or relevant). I tried force_audio option, and it didn't work either.
DELL U2410 ELD reports OK but cannot hear DP sound

Do you have idea why they don't work?
BTW, can DP-audio work with these monitors on other OS...?
thanks,
Takashi
