Hello,
I saw the commit in tiwai/sound. I noticed that 3900 was used for the 
boost_peak_milliamp value. I just wanted to note that as far as I can 
remember that is the value that the Windows driver uses, while the 
malformed but readable _DSD specifies 4500 (at least mine does). I don't 
know which one is correct, but 3900 is probably on the safer side I guess.
