There are two possibilities how the _drain() can be implemented:

Please, see to refine code in pcm_dmix.c. You cannot do it with your way.
The refine means that it reduces given configuration and if no valid
configuration for given parameter exists, then the result value has to be
empty (or not set).
Okay, so, where I tried to do something like (not
The API does not *need* to set the FD_CLOEXEC flag,

Hi,
Is Alsa-Dev the right place to report problems with Linux MIDI? (Such as
stuck note problems with soft synths.)
Thanks,

You can still unset the flag yourself __if you

2.4.20 - it's a heavily patched one, tho (out of gentoo's portage).
should i try a vanilla kernel?
the new code on rc7 simply tries allocation via vmalloc().
if it fails, it means that the system resource is really exhausted.
