I still don't know whether your issues is with pcm0 (snd_ich) _or_ pcm1 (snd_uaudio, hacked? What kind of hack?) _or_ _both_ . If you insist on not using (or even _trying_) the binary modules, look for the patchset in the above directory. Disable acpi_throttle (read, "acpi_throttle", nothing to with powerd or est or speedstep) if that matters. -- Ariff Abdullah FreeBSD ...
