Basic questions about latency and integrated peripherals...

Okay. To start with, I discovered upon installing UbuntuStudio that the on-board integrated graphics in my Dell Studio 540 were unsupported. That's fine, because I actually have an nVidia graphics card that I was using anyway. Fair enough. Now for the weird and probably unsettling question: Is it possible to use both the on-board graphics and the on-board audio (the outputs that came with the computer from the factory) at all with 64Studio or UbuntuStudio? And what kind of audio latency can I expect to get from the integrated audio? Right now, I have an m-audio Delta 24/96. It is a good, solid PCI card that delivers about 5ms of latency at around 256 buffers. That isn't bad, and mostly because I have a quad-core Intel processor. But I want to know whether I can get similar performance out of the integrated Intel audio chipset. The other problem is that the m-audio doesn't seem to work with Linux. That doesn't surprise me, but it creates problems for me. I am pretty sure that the on-board audio will work, but I have no way to test it right now, because I would need to find drivers for my Novation ReMOTE, and I would have to find some suitable sequencing software to test things. (By the way -- when I refer to latency I'm really talking about the amount of time that it takes between my pressing a key on the keyboard and being able to hear an instrument -- say, like playing Omnisphere...) I get off on trying to maximize the polyphony while getting ridiculously low latency. I'm looking for the best way to achieve this, and I'm constantly amazed at how little thought this has been given to by the software companies -- in particular those who develop for Windoze. I mean, come ON! Why can't we just get awesome performance out of machines that are so bloody POWERFUL?! (And no, not trying to post flame bait here... just having some fun is all...) :) I know -- you're probably laughing hysterically... as in -- "you want WHAT?!" But a guy can dream. And the reason why I would want this? Simple: I'm a prospective developer, and I'm looking to cut out the middle-man, so to speak... or the MIDIman in this case (sorry if this humor is too obtuse...) :) TWM

I have used Delta 24/96 with 64 Studio, works beautifully and out-of-the-box. I have not tried it with 3.0beta though. Can you see it (ice1712) when you hit "lsmod | grep snd" in terminal?

on board audio would be

on board audio would be trash compared to the m/audio. The Card you have is here http://www.alsa-project.org/main/index.php/Matrix:Vendor-MAudio ? if so its supported by alsa so its a set up problem. Narrow down what you want to do into separate bits, get the audio sorted then the midi. Hope I don't sound like I am teaching granny to suck eggs. Very new myself and am noticing that there's a lot of threads going in about 20 directions at once - hard to follow, especially when there's scripting being bounced around. hope somebody chimes in with the missing info for you asap iain
