Hi folks, Just tried to install alsa 1.0.23 on top of Debian Squeeze (kernel 2.6.32) to get things like snd-aloop. However it seems that snd-ice1712 cannot be built. The acinclude.m4 file says that the driver depends on CONFIG_BITREVERSE, which is set in the running kernel's config. Not sure where to go from here... Peter.
