(5.1 player)? Playback of anything, including timidity and MP3 seems stuttery and hesitant. It's hard to put into words, but it's similar to the effect you would get when playing back a stream and the input can't keep up with playback. I've removed all the debugging entries from my kernel config, but nothing seems to help. System: Gigabyte GA-K8VT800 Pro socket 754, Via KT800 chipset, onboard sound disabled. AMD Athlon 64 Newcastle 3000+ CPU 1GB DDR 400 Radeon 9200SE AGP 8X SB Live!

Although this is an amd64 machine, I'm running i386 as some ports I need do not work on amd64. The card itself is on an IRQ of its own in a slot which does not share a PCI interrupt with anything else. It worked fine on 5.4-RELEASE. I'm simply trying to decide whether to file a PR or not and suggestions on gathering relevant information to do so would be appreciated. -- Matt Dawson. matt@mattsnetwork.co.uk MD2657-RIPE OpenNIC M_D9
