Hello all; I'm new to the list, and sitting playing with a pair of Edirol DA2496 cards.

These support Word Clock synchronisation, which can be done using S/PDIF, a 75 ohm coax cable on the breakout boxes, or with a internal jumper cable between the PCI cards. Unfortunately neither the driver, or Mudita24, were exposing access to the Word Clock.

I've managed to patch support into both; doing so with the 3.12.13-rt21 kernel, and mudita24-1.0.3+svn13 from the Ubuntu repositories. This is, mostly, by treating the cards the same as the Delta1010LT.

Forgive me being so rusty with C that I've not provided a patch; going to have to redo this and actually build proper diffs for it.

I do have a related query, about Xruns - when using an .asoundrc file to merge the two cards into a single virtual card - is there any way to properly suppress backend Xruns that have no impact on the actual recorded audio?
