Harry. Great news! Thought I had read previously they work well but worth double checking before buying. Yeah I know about the DJx, but as my desktop has been in bits for many months and not sure if/when I am likely to put it back together (build a new one) I feel it is worth having the recording capabilities on the laptop. ExpressCard slot on my laptop comes off a Texas Instruments chipset so I believe it should work very well. Regards, Dale. (PS on lists like this should I reply below so it's easier to read for people on Digest versions of the mail, rather than above like I have done? Been a while since I used many mail lists but sure I remember something about down-posting rather than up-posting...)

I've got an Indigo DJ here (that's 2 stereo outputs, one headphones level w vol control, the other line). If you don't need inputs perhaps that's a good choice? As far as support goes, assuming your PCMCIA slot is good, it works *extremely* well. I'm running 5 ms with it, on a moderate laptop and assuming your JACK graph isn't too heavy it won't xrun at all. Very happy with it. Slight drawback is that one needs the "echomixer" (part of alsa) to control the volume, as it provides 8 virtual outputs. But the echomixer is a good tool, and if you don't need to reconfigure it, it keeps its settings from last use. I picked mine up 2nd hand for a great price, perhaps worth checking out the 2nd hand market?My advice: buy it. They're great :) -Harry

Keep in mind I have the "DJ" not the "DJx", so I'm using the PCMCIA, not the ExpressCard. The ALSA matrix has no mention of the DJx.. so I can't confirm. http://www.alsa-project.org/main/index.php/Matrix:Vendor-Echo_Corporation Their Developers section with the generic driver only mentions PCI/PCMCIA not PCIe/ExpressCard too and was last updated before the X series of cards were release. Googling I can find a couple of people asking the same question but not the answer... EG. http://www.linuxmusicians.com/viewtopic.php?f=6&t=7216&p=21260 and searching for either djx or iox brings that thread as only result. OK links saying it should work as long as you install alsa-firmware as the binaries have been included in there so it should be good :-) And even that may be old, getting confused but everything points towards the positive, which is good. Dale.
