[PD] [OT] New machine - sound hardware?

Hi all,

Been off the list - overworked and ill...

So, after my laptop was stolen, I bought a new one. But really a new one, so now I have some serious problems...

Technically this does what I need in every way but sound hardware. Two instances of PD use seperate processors of the CPU, so sound and PDP can run in two PDs ;~) Well, The audio latency is 280ms and I still get dropouts. Damn you Dell ;-{

BUT - there is no PCMCIA cardbus slot. Only a new expresscard slot, which might become useful given a year or two. Of course I am hoping that there is a solution to my audio hardware problems, so I ask a few questions now.

1. Has anyone a working firewire (ieee1394) interface with their laptop that runs with low latency (<16ms, MIDI in to audio out) under Linux with PD? What is it and what driver (ffado? freeBoB?)

2. What MIDI interface under Ubuntu? I have tried and tried again to get a Midisport 2x2 working with both the source code (both versions - 0.5 and 1.2) and the Ubuntu packages - no luck!

3. USB audio interface? I know this is a long shot...ALSA has never worked with PD on any computer I have owned.

There is also the expresscard interface - for which their are only two soundcards AFAIK - Creative X-Fi (support has been dropped, and no source code available) and Universal Audio X-Pander (I can't afford it, and there's no Linux support as yet).

So, are there any really good reports of successful hardware/linux combinations? I really think we and the rest of the Linux community need to crack this. I'm not a good enough software developer to write drivers and I don't have much time right now*, but the best hardware is firewire these days, and RME don't make a PCMCIA expresscard interface.

Searching the archives lead me to few emails, one success with freeBoB and an Edirol interface was the only optimism I found. PD under Linux has become pretty much useless with this new computer - dropouts everywhere. (PS, Window$ Vista is the operating system that stops you operating, and is bad with every audio program I have found).

But as the old computers die, we'll be left with these machines with their altered hardware configuration. It's getting harder and harder to run PD on new hardware.
