Thank you for your help!
I've done more tests using the oss emulation in ALSA, and I have
encountered a problem.
In a previous mail Mark you mentioned this:

What happens if the user wants to change the master clock divider at
runtime - for example, when changing sample rates?
I had actually a crash because of this, so I will send a patch to
correct it(I simply removed it since I don't thonk it is needed).
