I think my problem is more basic: If I'm correct, I should see the Link light activated. It's not, and I'm pretty sure I'm missing a step or two in the configuration. I'll keep working with it.

multi processor

by alex stone

I've done a bit of googling, but can't seem to find or understand information about linux (audio and vid specific, for example writing for film) and multicore, multi processors. Example being a Mobo that supports quadcore/ 4 cpu. (Tyan) Anyone using one of these monsters for audio/video, with linux? If so, what's the performance/compatibility like? Driver/module issues, things not working, etc.. Alex.

New Linux DAW build. AMD790GX chipset working OK?

by R.Wolff

Hi there, I'd like to build a new DAW in the next 2 weeks. Budget is tight and so I have chosen the following components to buy: CPU: • AMD Athlon X2 7750 Black Edition (K10 - Kuma core), 2x 2.70GHz, boxed AD775ZWCGHBOX - €68,21 Cooler: • Arctic Cooling Freezer 64 Pro PWM - €16,65 • http://www.arctic-cooling.com/cpu2.php?idx=80&data=1&disc= Mainboard: • Asrock AOD790GX/128M AMD790GX - €84,03 • http://www.asrock.com/mb/overview.asp?Model=AOD790GX/128M Memory: • 2x2048MB Kit OCZ Platinum XTC 1066MHz CL5 - €44,87 • http://www.ocztechnology.com/products/memory/ocz_ddr2_pc2_8500_platinum_sli… Power Supply: • RASURBO GaminX & Power GAP565 - 550 Watt - €43,95 • http://www.rasurbo.de/netzteil_gap565.html Any thoughts on this? What I'd like to know the most is, how does the AMD790GX perform under Linux? Is it fully supported (chipset, graphics [very important], Which kernel would I need at least? Does anybody here use an AMD790GX board? Are you happy with it? Any known problems? I'd be really grateful for any thoughts, experience, info, whatever. Greets, Raphael ;) -- ________________________________ "A mind is like a parachute - It doesn't work if it's not open." |- - - - - - - Frank Zappa - - - - - - -|

Re: [LAU] Ardour crashing with error about not being fast enough.

by Brian Bergstrom

Okay, so after continuing my search for a solution I can across someone with a similar problem that ended up being cause by a bug in a effects plugin(freeverb). I had about 10 plugins in my project and I narrowed it down to the one causing the problem! TAP Equalizer. I don't know what the actually problem is, but it causes ardour/jack to fall apart. Upon checking out the website for TAP it looks like development has been dead since 2004 so I don't know if it will be fixed. Ardour Rocks.

Re: [LAU] using a condensator microphone live
