Something wron in sound under linux emulation under recent current

[Vladimir Grebenschikov]

Hi

After upgrade to recent current (previous was in February 2007).

I have notice that heroes3 (linux game) stop working, after some
investigation I've found that it blocks on start just after opening
sound device (truss output below).

If I start it with disabled sound - it works as expected.

It works fine several months ago.

Other Linux sound software looks ok (skype).

$ truss /usr/local/games/Heroes3.Linux/heroes3 -l

And then it sleeps forever here.

Any hints ?
