Talking about USB, going lower than 64 frames/period

with no TDs queued?
Is there anything I could do about that or is this the very limit this
system can handle? No problem anyway since I barely run lower than 128
frames/period normally and even at 64 this system is pretty stable with
bigger projects. But I just like to know how low this notebook can go.
It's an AMD Ryzen 7 system so USB controllers are from AMD (USB ID's are
1d6b:0002/0003)
I've resolved this by passing implicit_fb=1 to the snd-usb-audio driver.
I can now go as low as 1ms systemic latency without choppy audio or the
logs filling up.
Best,
Jeremy
