Hi Jaroslav!
thanks for quick reply and hints!
I finally understand the inverted POLLIN/POLLOUT in dmix. As a quick
check I added writedev to fds set and it worked, now I'll able to
write a patch using poll and demangling revents...
First level documentation on www.alsa-project.org says that you may
use select or poll as you need, should be this corrected?
Thank you again!
Nicola
