It's liekly linked with the old libasound.

SALSA-lib is a source-level compatible library and it's _not_
binary-level compatible.  Thus, it's no drop-in replacement.
After installing salsa-lib (better use --enable-everything option to
make a libasound symlink), then you'll have to rebuild the other apps
linked with alsa-lib again.
