I have all three, and soon four ( just won http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=290470230872 Terratec EWS88D ADAT/SPDIF card for $19.99!) ice1712-based cards all of which have excellent digital I/O sections. The digital I/O and ability to use the onboard mixer to send audio to/from external effects makes it easy to get a "digital channel" insert wherever you need it, or get SPDIF from a sampler, or audio from my other computer (i've jury rigged a sort-of digital matrix router out of radio-shack passive video switches)... anyways the SPDIF or AES/EBU digital I/O works well and its integration and routing flexibility is one of the strong points of the sound card. With the DAT recorder, just be sure to have the card running at 48K, or even better, set it up to get sync from the spdif input. This looks like http://code.google.com/p/mudita24/issues/detail?id=2 . This is an Audiophile 2496 handling bug in Mudita24, but it should work fine even with the error message displayed. Unfortunately, it also means the Audiophile 2496 doesn't support the "delta input status". However, if this value can't be retrieved, it doesn't mean your card doesn't have a working digital input. For one, unless the card happens to be running at more or less the same frequency as the digital input you won't see any signal on the input. Such non-locked "free wheeling" synchronization is far from ideal, but in practice, I don't hear any desyncing or noise when doing this with M-audio "Delta" cards (not sure about how Audiophile 2496 performs in this context). These allow digital inputs to be active from an externally clocked source, even while the card is internally clocked -- as long as the rates are the same. Other cards, like the terratec dmx6fire, won't see any input from SPDIF unless the card is eternally clocked sync'd from SPDIF. It is possible the Audiophile 2496 acts more like the dmx6fire and requires the card be externally clocked if the digital input is being used. I agree that this would be a good feature -- some kind of compact mode, perhaps just showing the meters, as well as a more interactive mode with sliders and buttons. (Pls make a feature request at http://code.google.com/p/mudita24/issues/entry .) Tim E. Real made a patch to mudita24 that uses different sliders for the mixer, and thus the mixer meters and sliders can be resized. Unfortunately, it can't be made much shorter than 385 pixels. Perhaps Tim can tell us whether his rework of the sliders have the potential of displaying any smaller than that. However, the minimum sizing might still be determined by the layout of the "profiles" or "patchbay/router" panels, both of which are quite tall. Patchbay/router could potentially be shrunk a bit by getting rid of extra vertical whitespace in the larger sized "digital mix" and "pcm out" rows and just use the horizontal-separators to make them visually distinctive. If you want to try out TIm's changes, the patch is here ... http://lalists.stanford.edu/lad/2010/08/0059.html ; I'm awaiting the rest of Tim's changes and then hope to release mudita1.04 when they're ready. (Tim, status??) -- Niels http://nielsmayer.com PS: My response/accept of http://code.google.com/p/mudita24/issues/detail?id=2#c1 ////////////////// Looks like I made a mistake in adding the Audiophile 2496 to the set of M-Audio cards that support the "Delta IEC958 input status" display. Which means this field will not be displayed at all once the issue is fixed, when using an Audiophile 2496. The cards that will support this feature will then be if ((card_eeprom.subvendor == ICE1712_SUBDEVICE_DELTA1010 || card_eeprom.subvendor == ICE1712_SUBDEVICE_DELTA1010LT || card_eeprom.subvendor == ICE1712_SUBDEVICE_DELTA66 || card_eeprom.subvendor == ICE1712_SUBDEVICE_DELTADIO2496 || card_eeprom.subvendor == ICE1712_SUBDEVICE_DELTA410)) Note that this value can be tested with amixer -c M66 cget iface=MIXER,name='Delta IEC958 Input Status' numid=50,iface=MIXER,name='Delta IEC958 Input Status' ; type=BOOLEAN,access=r-------,values=1 : values=off Hopefully ICE1712_SUBDEVICE_DELTADIO2496 and ICE1712_SUBDEVICE_DELTA410 as "Delta" cards, will support this supposedly delta-specific feature. I do not have those cards to test against, and they're probably quite rare and hard to find. //////////////////// PPS: If anybody has a Delta410 or DeltaDio2496, please send me the output of "amixer cget iface=MIXER,name='Delta IEC958 Input Status'"
