[Pkg-alsa-devel] Bug#913409: libasound2: plugging in RME ADI2-DAC causes pulseaudio to crash in libasound2

[Michael Stapelberg]

The steps I used to verify the patch were:

% wget '
http://git.alsa-project.org/?p=alsa-plugins.git;a=patch;h=a4e7e1282c57a2f4e83afe9a4008042d8b4c5bb9'
-O /tmp/alsa.patch
% pk4 libasound2-plugins
% patch -p1 < /tmp/alsa.patch
% pk4-replace
