- add cache_size value to snd_pcm_hardware struct - here will be stored area of buffer which might be cached in the hardware for large FIFOs including prepared USB's URBs (the upper layer should not work with this buffer area - rewind operation etc.)
I already submitted a similar patch quite ago. Actually, it exposes the delay account in snd_pcm_status() delay calculation. The delay value can be dynamically changed.
The current test patches are found on sound unstable tree topic/pcm-delay branch. git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound-unstable-2.6.git
Looks good. Could you pick these patches to your stable tree so we can stack other patches on top?
FYI, the patches appear now in topic/pcm-delay branch of sound git tree, and merged to master branch, too.
