Hi,

Please does the current USB audio driver support multiple transactions per microframe (high-bandwidth mode)? I could not find it in endpoint.c but it may be there or somewhere else :-)

This should be transparent for the driver. See usb_submit_urb() function from drivers/usb/core/urb.c. It allows packets larger than 1024 for isochronous transfers over High Speed and Super Speed buses.
