The difference is this mechanism puts the file under your control at ~/.envy24control/profiles.conf and allows you to set eight different profiles: allowing you to save or restore up to eight different "asound.state"-like configurations per card. The different profiles are most useful for storing routings set in "Patchbay/Router" panel, as well as "Hardware Settings" panel clock rate, or external SPDIF/wordclock sync. On cards with switchable spdif/optical ins (Terratec/Terrasoniq), you can persist this extra level of "routing" -- which is useful for "matrix routing" between two digitally-interconnected and sync'd computers. ( I use profiles named: 44dmix-to-1&2&spdif, 48dmix-to-1&2&spdif, spdmix-to-1&2&spdif, 44all-outs-pcm, 48all-outs-pcm, spdif-all-outs-pcm, 96dmix-to-1&2&spdif and 96all-outs-pcm. ). When you have a combination of settings in envy24control that you want to return to, just go to the "Profiles" panel, enter the name of the profile into the first free text field (initially these will be numbered "1" through "8"). After entering a descriptive name, click "Save active profile." To restore a given profile, just click on the "button" area surrounding the text field, or even click within the text field. You'll notice the selected profile "button" indicates activation via coloration. After changing profiles, go to, for example, Patchbay/Router or "Hardware Settings" panels,and note that the previously saved state was restored. Note that significant amounts of setting data gets saved in these files: -rw-r--r-- 1 npm npm 115253 2010-08-07 23:10 profiles.conf For comparison: -rw-r--r--. 1 root root 128079 2010-08-07 18:15 /etc/asound.state (That's for a system with two envy24-based cards installed, thus size is large, causing "save" to produce a brief but noticeable pause in the metering on a slower system or "ondemand" throttled system). Niels http://nielsmayer.com PS: speaking of envy24 anybody know whether this will work in standard alsa/linux: http://www.lionstracs.com/store/msaudio-board-envy24-p-122.html and are those i2s connectors, or ttl-level spdif? i guess if it's i2s you have to get: http://www.lionstracs.com/store/mixer-board-p-210.html (which looks pretty cool, esp w/ the onboard dream-based hardware synth w/ large sample ROM).
