Subject: [PATCH] ALSA: ctxfi: Bump playback substreams to 256
Date: Wed, 24 Aug 2011 00:48:59 +0200 [thread overview]
Message-ID: <4E542E5B.6040005@gmail.com> (raw)
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.
