I have a Toshiba laptop system (dynabook 3380v) with integrated
Maestro 2E sound. 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. Tried kernels 2.4.{13,14,15-pre{2,3}}

Nothing immediately strikes me - could be its not got CLKRUN wired up
properly. What pci bridges does it have ?

Could you do a lspci -vv as root on that device both with AC and without?
(to see the dump of of the PM capabilities?).
Thanks,

Ok. Well if it is the CLKRUN stuff then I can give you a diff to try if you
are happy rebuilding kernels

It says in both cases that the device is in D2; ah yes, the device is not
open and the driver cuts the power on ess_release().
Are you noticing any performance degradation for any other devices?
(On a side note, it looks like the driver is manually touching a lot of
PCI config space rather than using the pci_ wrappers...)

Hehe... I just try to comlpy when others are helping me debug
my driver issues =)

Nothing glaring, but I can try to get some numbers if there's a
particular device you'd suspect.

Hard drive, video, and network (which is in the cardbus slot)
don't perform any differntly on AC vs. battery.

It does PCI power management in 2.2 as well..

Fwiw, the alsa driver for this device behaves identically to the OSS
driver in the kernel.

Another interesting finding here... whenever something else is
generating a lot of interrupts (specifically, those devices that
share IRQ 11 with the sound card), the sound actually comes out
correctly, or at least more correctly... still slow.
I noticed this at first while folding up a mozilla window in
windowmaker, I assume the X-server is interrupting on the
video card a lot there. hdparm -t /dev/hda also causes it.

Intriguing - so its as if the sound driver isnt generating interrupts
(one way to test that would be to monitor /proc/interrupts both with power
on mains and off of mains)

When playing a particular mp3 with mpg123, the rate of increase of that
field in /proc/interrupts is ~200/sec regardless of whether on AC or
battery. Of course, doing stuff to the other devices that share that
interrupt blow it up.
