FWIW my > > soundcard is a venerable 2496 Having been laid low by a cold, I eventually got bored and had a look at this again. I'm running only 64bit OSs on a quad core AMD. The MOBO is an Asus one with a uefi bios. I can't find anything on that bios that is relevant to irq or tweakable in any way that might benefit sound. I only have one PCI slot, and the soundcard comes out at irq20 which is below the usb irqs (interestingly the on-board sound is above usb). As a side issue I'm wondering if this fact is causing very occasional Xruns from ALSA - When I say occasional, I mean maybe once or twice in an entire afternoon session. Double-checking again. The 3.2 kernel behaviour is appalling, regardless of whether I use the vanilla one of the RT one, 3.1 is smooth as silk. -- Will J Godfrey http://www.musically.me.uk Say you have a poem and I have a tune.
