This works fine and dandy when on AC power, but when on battery, the sound doesn't play properly... xmms and mpg123 show very slow (1/10 or so) progress through the file and the sound that results is a staticky approximation of the correct output. The device shares irq 11 with the i82365 cardbus bridge, the NeoMagic 256va AGP chipset and the uhci usb controller. Driver output is thus: maestro: Configuring ESS Maestro 2E fount at IO 0xEE00 IRQ 11 maestro: subvendor id: 0x00011179 maestro: PCI power management capability: 0x7622 maestro: AC97 Codec detected: v: 0x83847609 caps: 0x6940 pwr: 0xf maestro: 1 channels configured. maestro: version 0.15 time 14:51:38 Nov 15 2001 I've tried with the power management both off and on, and with apm off in the kernel altogether.
