You can pre-allocate the 2735 PCM buffers by loading snd-page-alloc module 2658 PCM buffers by loading snd-page-alloc module and write commands to its 2736 proc file in prior, for example, in the early 2659 proc file in prior, for example, in the early boot stage like 2737 ``/etc/init.d/*.local`` scripts. 2660 ``/etc/init.d/*.local`` scripts. 2738 2661 2739 Reading the proc file /proc/drivers/snd-page- 2662 Reading the proc file /proc/drivers/snd-page-alloc shows the current 2740 usage of page allocation.
