From 391e69143d0a05f960e3ab39a8c26b7b230bb8a9 Mon Sep 17 00:00:00 2001 From: Maarten Lankhorst <m.b.lankhorst@gmail.com> Date: Wed, 24 Aug 2011 00:48:59 +0200 Subject: [PATCH] ALSA: ctxfi: Bump playback substreams to 256 There are references in the code to 256 sources, so I tested it with 256 aplays, of which the first and last with real data and the rest playing /dev/zero . Also increase amount of page tables, so the default aplay size works.
