Re: Re: Laptop and sound card for ubuntu studio
Thanks All! This thread has just the kind of info I need and will help me make a short list.I plan to use Pure Data to do effects on my guitar (in particular a kind of live granulation patch I'm quite pleased with) which is why low latency would be good. At some stage I'll be recording that using about 4 tracks simultaneously so the lappy will need some power (plus in Windows I need to do some heavy lifting for work). I've got a Zalman laptop cooler which I'd recommend if anyone has overheating problems. Keeps it quieter as well. Cheers!

I suppose with the 750i there will be more since it is quality hardware, but someone I talked to was unsure whether it would have good linux support. Anyhow.. It seems to be that the best choice is not to get the Core 2 Duo's but the i7, as it supports hyper-threading, evidently according to the wikipedia article on the i7, the Core Duo doesn't support hyper-threading.. Maybe that's just the core duo and not the core 2 duo, nope the core 2 duo doesn't, says it is a descendent of the Pentium 3 architecture. The Pentium Extreme is the one I'm building, is overclockable to 4.2 Ghz. Also said the Pentium Extreme has 31 stages in it's execution pipeline, but that the branch prediction penalty is greater with this many stages, but that the internal ALU's run twice as fast as the clock cycle to make up for it. All I know, from my discussions with my brother who's done work in things like fault tollerant systems, you need a high degree of branch prediction for linux because of the greater amount of indirection. I also read that part of the problem with the netburst is that it makes other operations go slower, and references to bit-shifting operations were given. If it has hardwired floating and integer operations, I don't know how much better it would be to have bit shifting operations since they are only going to improve multiplications and divisions by multiples of 2. I think a shared cache would be better than a divided cache, but it's a cheap chip, cost me 99 dollars at tiger direct. A Core 2 Duo would probably run me more and i7's that compare to the Pentium Extreme in having hyper threading, go from 200 to 1000 dollars. I'd rather get the best of the last line, than wait for the best of the next.

A lot has changed in the years since the P4, and for the better. Netburst is dead, hurray. The PIC has been replaced by the APIC. If you care look them up in wikipedia, the point is that a modern machine will not look like the above, and this is not only to be expected, but is a good thing. -- Ubuntu-Studio-users mailing listUbuntu-Studio-users@lists.ubuntu.comModify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users -- Ubuntu-Studio-users mailing list Ubuntu-Studio-users@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users

Re: Stability problems with 9.04 64bit quad core
Did you get the 64-bit kernel? Cause I'm not sure the 32-bit kernel can address more than 4 gigs.

I have a Dell Studio desktop, Core 2 quad 2.33, 6gigs DDR2. I was running the same setup on 8.10 with only minor problems. I get xruns, jackd crashes, ardour crashes with the vanila kernel, and most recently my entire computer becomes unresponsive with the real time kernel. Also system monitor says I only have 3.1Gib of ram and 3.1Gib of swap. Also your swap needs to be at least 1.5 times your real memory. So you have 6 gigs of ram, you need a swap of 9 or 10 gigs. It probably scaled your memory down because you didn't allocate enough swap, the swap is part of the virtual memory, and the more swap you have, the more virtual memory you will have. Like if you have 10 gigs, you will have 6 gigs real, and 4 gigs virtual. That's what permits you to work on large images in GIMP and juggle bunches of programs. It's not so good for audio applications though. You probably can turn it off. There is also a way to make it so that swapping of pages out to the storage, happenbs less frequently. But I forget where that information is in the configuration files. -- Ubuntu-Studio-users mailing list Ubuntu-Studio-users@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users
Re: Stability problems with 9.04 64bit quad core
Also I heard 8.10 is the version of Ubuntu that had the multi-core realtime kernel issues.. I've heard the best are 8.04 or 9.04.. Skip 8.10.. 8.04 for Ubuntu Studio is said to be more stable, but it works fine in 9.04 .. You might want to check your /proc/interrupts to see if you have multiple things sharing the same interrupt, like if your hard drive is sharing an interrupt with your sound card, that's probably what is causing a conflict, the swap is inadequate and so the hard drive is busy swapping memory and jack is unable to manage the sound card. I'm just guessing.. instability problems? Do I need to go back to 8.10? I haven't been able to duplicate the crashes as they seem unpredictable. I can sometimes get it to crash by scrolling/resizing. Maybe its the video chipset, I have the intel GMA 4500HD chipset. -- Ubuntu-Studio-users mailing list Ubuntu-Studio-users@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users
Re: Stability problems with 9.04 64bit quad core
If it is an interrupt problem, you'll have to move your sound card to another slot.. Or if the sound is on your motherboard, buy another card and use that instead of the motherboard. Also I think the 64-bit kernel is the other problem. I think I read somewhere that Linux doesn't permit you to use the full 4 gigs of ram, that you get something less than 4 gigs cause the rest of the address space is used for addressing devices. I had to disable my onboard sound card and put a soundblaster card where my firewire card was cause the firewire card had it's own interrupt, and my NVidia card was sharing an interrupt with my motherboard's sound. -- Ubuntu-Studio-users mailing list Ubuntu-Studio-users@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users

I think I read I mean to say that the 64-bit kernel is the solution to your memory addressing. If your swap is adequate for the amount of real memory you have, then it's likely the kernel is not a 64-bit kernel, and that's why it's not addressing enough of the memory. And the size of the memory could be less than 4 gigs due to some sort of addressing needs outside of memory addressibility. If it is that your swap is 3.1 gigs, then that's the problem. But make sure you have the 64-bit kernel and enough swap. -- Ubuntu-Studio-users mailing list Ubuntu-Studio-users@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-studio-users

I continue to try, but the card still does not work via USB in Linux. any help is much appreciated Maybe this is true?

Re: Usb Fast Track Maudio
Hello, If your system see it, it should work ! I am pretty sure you have checked but anyway: I also use the M- audio Fast Track usb with Ubuntu and the Gnome desktop ( not ubuntu studio but i am sure it makes no difference). So did you change the sound properties and select the usb device for playing and recording sounds ? It works perfect on my computer. I use this card for quite a long time because the computer native sound card is awfull when i want to play music...
