The default is to use larger intervals.
The usb-audio driver behaved in a BATCH way in the very early version, but it was improved.
The delay reporting is more precise, but the DMA position still jumps for each URB.
So we can get rid of the flag from this driver now.
How well does timer-scheduling work with large URBs?
I thought PCM runtime delay should give the accurate sample position, irrespective to URB size? It should suffice for PA to control via timer scheduling.
