The problem is quite simple: this USB card does not support DMA transfers (yes, seems impossible but that's what it is), so a support for this sound card is difficult to obtain working on the snd-usb-audio module, Takashi told me to use an intermediate buffer, but I really don't know how to do it. Should I copy data from the buffer (playback) on usb transfer completition callbacks? But in such case isn't it the same to just copy data into the urb's transfer buffer?
I tried to avoid using this buffer and what I obtain is something that resembles what the card should be playing but with huge noise.
Please help!
