The version of envy24control in latest (alsa-tools-1.0.22) works great. diffing levelmeters.c with the one in 1.0.20 shows me that the new kernel brought in a newer alsa driver, that required a a change of SND_CTL_ELEM_IFACE_MIXER to SND_CTL_ELEM_IFACE_PCM. I'll be submitting a bug to the gentoo packagers to update the alsa-tools ebuild with the latest.... It would have taken me (having never working on ALSA sources, and not knowing the history, a __long__ time to figure this out!
