[alsa-devel] [PATCH] aplay: increase channel limit to 256

[Tim Blechmann]

aplay is limited to 32 channels, which makes it impossible to use it for
testing devices with more channels. here we increase the limit to 256,
which should be sufficient for a virtual device made of 4 64-channel
soundcards.
