Any ideas what's happening here? I'm trying to pop on some of the suggested and recommended packages for mplayer: alsa-utils is one of the dependencies. I get:

Unpacking alsa-utils (from .../alsa-utils_0.9.8-1_i386.deb) ...
dpkg: error processing /var/cache/apt/archives/alsa-utils_0.9.8-1_i386.deb (--unpack):
trying to overwrite `/usr/bin/alsamixer', which is also in package knx-alsa
dpkg-deb: subprocess paste killed by signal (Broken pipe)
Errors were encountered while processing:
/var/cache/apt/archives/alsa-utils_0.9.8-1_i386.deb

Ideas welcomed -- does it look like I have to bin knx-alsa and rebuild it from Debian?
