[Pkg-alsa-devel] Bug#913706: libasound2: Using a BOSS BR-800 results into a segfault in libasound2

The output is:

ii  alsa-firmware-loaders 1.1.3-1 amd64        ALSA software loaders for 
specific hardware
ii  alsa-tools 1.1.3-1 amd64        Console based ALSA utilities for 
specific hardware
ii  alsa-utils 1.1.7-1 amd64        Utilities for configuring and using ALSA

plugins
ii  libsox-fmt-alsa:amd64 14.4.2-3 amd64        SoX alsa format I/O library

But I also tried the current masterbranches by building them myself and 
installing them via make install (not sure if that properly worked)
