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??

Capture works perfectly fine.
Playback does not work with alsa apps or with jack.
This is my /proc/asound/cards output
0 [SB ]: HDA-Intel - HDA ATI SB HDA ATI SB at 0xf9ff4000 irq 16 1 [Ultra ]: USB-Audio - Fast Track Ultra M-Audio Fast Track Ultra at usb-0000:00:13.5-1, high speed
This is what happens when trying to playback a sound file with aplay -D plughw:Ultra /media/Edipo/Triangulo/Hadas\ por\ ahora.mp3
aplay is not capable of playing mp3 files. Try a .wav.
Also, note that the patch you tried is preliminary and not intended for productive use. It might crash your kernel.
We need some conscenus about how to decouple the USB stream from the ALSA stream internally to finish it.
