Hello LAD, I'm working in company which is
developing a guitar pedal board
which runs Linux (arch) and my task now is to make the kernel's usb audio
driver more appropriate to our sound card. I'm kinda lost in this since i
have a brief knowledge on usb protocol so I was hoping that you could give
me some directions on how can I optimize the driver latency wise, any
tips?
The ALSA USB Audio driver is already highly optimised. If you are seeing
specific issues the alsa-devel mailing list is a better place to discuss.
Or are you looking to optimise the kernel and operating system?
FYI, other LADers have been using usb devices with 64 frames per period
which provides less than 2ms round trip latency.
