[alsa-devel] M-Audio FTU issues

[Juan Pablo Bouza]

Yes, I know about the duplex mode kernel crash... But anyway, playback is just broken with the patch and my compilation...

Against what version of kernel 3 is the patch supposed to work?

Is there any additional kernel configuration option I should or should not use in order to make the patch work??
