Hunch: if the meters work once, the meters work, IMHO. This is a clocking issue. Also, if talking of the level of the "Digital Mixer" meter to the left, you have to make sure that the inputs to the digital mixer are "live." However the mention of "stuck state" means the ICE1712 metering registers are putting out DC at the digital level that they were at when they lost clock. The issue is probably somewhere else. I've seen this sort of thing happen before with the ICE1712 chips when they're "locked up" waiting for clocking, perhaps because the external spdif input in "Hardware Settings"->"Master Clock"->"S/PDIF In" is selected. Even more likely, there's a lockup, because "Multi Track Rate Locking" or "Multi Track Rate Reset" are selected in "Hardware Settings". Deselect, kill any processes using the devices, and start over again. For details, see http://alsa.cybermirror.org/manuals/icensemble/envy24.pdf :-) The lockup will "stick" if the audio device is in use, for example if pulseaudio has grabbed it, or if it's still lingering around in some spinning or zombie jackd. So changing the settings in the ICE1712 control panel may not actually take effect until the device is relinquished and can be overridden out of it's locked state via the control panel. Note that this is all said as a hunch. I am not even running an OS that supports the latest GTK changes and I am a Fedora user so there's little chance I'll switch to Ubuntu without getting paid for it. So I guess I'll find out if it's related to later versions of ALSA, GTK, or Linux next time I setup a new machine.... and then I'll stick the Terratec and it's lovely enclosed Yamaha DB50XG clone (NEC XR385) into the new machine, pull down the latest mudita24 from SVN and give it a try again.
