Hi: I have sound support built in to the kernel, so this seems not to matter. I would guess that if your kernel is compiling properly then the includes must be OK. As far as your user vs. root problem goes, remember the sound devices were recreated with sndevices, so it's quite possible that user and group details or permissions may have changed. Make sure that your user account has access to the devices. I'd suggest making them group read/writeable and put yourself in that group. As for unmuting, remember you need to both unmute and set volumes for both the master volume and one other source (e.g. pcm). The need for this should be pretty obvious.
