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.
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?)
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!
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.
Best, Ed

I've been using a firewire presonus firepod with the freebob drivers under linux. With Ubuntu Studio and the real time kernel I can get around 2-5ms with no dropouts. It also works in OSX and windoze. The midi also works fine. The presonus has been good so far, well designed, metal case, lots of 1/4" jacks 24/96. They lie a bit on there spec sheet. They claim it's 10 in 6 out, but in reality you get 6 x 1/4" ins and 4 x 1/4" outs with a stereo digital spidif in and out ganged up on the midi breakout cable. And I think they let you replicate an output on your headphone jack, but it's not truly another out, at least as far as I've been able to tell. As far as a $325 CDN soundcard goes, it's pretty good. I also have a midisport 1x1 that works fine in ubuntu.

- Has anyone a working firewire (ieee1394) interface with their laptop
i have a macbook pro with a presonus firepod (firewire) running linux with freebob (ffado is not ready). the latency testing patch in pd gives me around 12 ms, but jdelay is 7 ms. the only annoying thing with my setup is that i have to rmmod ath_pci to avoid glitches (pretty weird).
i am waiting for the first release of ffado. maybe it will fix this problem. pat
hi patrick
I have a terratec phase X24 and the only problem I have is because of the firewire controller on my laptop (IBM X32) which seems to be crap (a Ricoh). So it is not the soundcard. I was told on the freebob list that I should buy a PCMCIA firewire card to solve this. I disabled cron and anacron (one of them was starting updatedb causing big trouble with jack) and I stop the wifi card while I use the soundcard. I also compiled freebob and jack from latest stable source. After all this it works better, jack still quits but takes couple of hours to happen.
Regarding PD I get clicks when switching desktops, I use Fluxbox on Ubuntu Studio. This does not happen with other software like Supercollider. I guess I need to play around with PD startup flags. I havent tested latency with test patch. Thanks for pointing into the ath_pci issue, I will test to see if this makes any difference.

My trick for getting updatedb turned off is to remove the 'slocate' package that it's a part of. Took me some time to figure that out.

i used "sudo sysv-rc-conf" to disable cron and anacron, as well as some other processes

FFADO is the new name for FreeBoB.
- 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!
I'd recommend to get a different Midi USB device then. (Older) M-Audio usbmidi devices were funky, better go with some Edirol or ESI/Audiotrak devices.
- USB audio interface? I know this is a long shot...ALSA has never
worked with PD on any computer I have owned.
USB audio generally works fine, but again: avoid M-Audio USB audio cards to be on the safe side. (However the the re-labelled midi controllers by Evolution/UK which M-Audio bought some time ago are well supported by Linux.)
For all things USB check www.qbik.ch for working devices. Edirol or Terratec or so are well supported and good quality.

morning Ed, morning all,

At the risk of re-iterating said optimism, I can only say that I am in fact (still) quite happy with my Edirol UA-25 (USB): 2in (symmetric) / 2out (asymmetric) + MIDI, running debian unstable with a patched 2.6 kernel on an IBM/Lenovo T42 (which I bought about a year ago after my laptop was stolen: you have my deepest most heartfelt sympathies). Good luck!
marmosets, Bryan
