In the tree unstable (~x86), there is alsa-lib-1.0.25, but alsa-utils is still at 1.0.24. alsamixer from 1.0.24 segfaults for me with alsa-lib-1.0.25. If I bump alsa-utils manually to 1.0.25, alsamixer works again. Reproducible: Always Steps to Reproduce: 1. run alsamixer from alsa-utils-1.0.24 and alsa-lib-1.0.25 2. watch it segfault 3.
