[pulseaudio-discuss] [PATCH 02/10] tests: Fix potential out-of-bound access violation in svolume cpu-test

[Peter Meerwald]

From: Peter Meerwald <p.meerwald at bct-electronic.com>

nsamples should be forced to be a multiple of channels; do so correctly
and don't make nsamples larger than it actually is
