USB Audio Codec choppy
No regression saw here. I'm using Linux Libre kernel 3.10.1 X64.
I think it is a bad idea to connect an USB DAC through a HUB, though.
Even a mouse gets choppy from time to time in spite of being the only
thing on a HUB. The last time I did this I was still using Windows 7 and
it didn't work for

Hello Joseph,
The not-reverted debug kernel that you had just built fails to boot on my

It seems that Alan's asynchronous DAC is not the only one that worked
fine. My friend has an Arce MDAC2 which however is labeled
asynchronous, not affected by this bug. That DAC supports only two
sample rates: 44100Hz and 48000Hz at 16bit. I happen to know it use a BB

I took a look in the information of the commit that caused the regression:
