I tested the patch today on Archlinux and I can confirm that it is working.

I am able to play DSD files up to DSD256, the maximum supported by the sound card.

I only compiled the snd_usb_audio module with the patch and replaced the stock one.

DSD playback was confirmed by the green LED on the soundcard and by

checking /proc/asound (altset 3 is used during DSD playback).
