[BUG] 2.6.x ALSA sound is pretty broken

[BUG] 2.6.x ALSA sound is pretty broken

[Hetfield]

i've got hard problems with sound in all 2.6.x, even 2.6.7 kernels.

with 2.4.2x or windows i've got no problems, so i'm sure it's kernel and
not hardware related.

the problem is that sound jumps, flickers and isn't good when harddisk
reads lots of data (i mean not 1-2mb but 60-100mb and more)

i checked irq and there is not conflict, i setted a higher and lower
value of latency and nothing changed.

i've the same problems since 2.6.0 kernels. Vanilla and Gentoo too.
I've tried lots of solutions, like disabling preemptile kernel, adding
alsa and oss, only oss, only alsa, as module or built-in.
nothing changes.

my audio card is a Creative SB PCI128, found by linux as


0000:00:0b.0 Multimedia audio controller: Ensoniq ES1370 [AudioPCI] (rev
01)
        Subsystem: Unknown device 4942:4c4c
        Flags: bus master, slow devsel, latency 32, IRQ 10
        I/O ports at b000

while on Windows i use es1371/3 drivers.
however with 2.4.x i always used es1370 alsa module without problems.
When harddisk is sleeping sound is normally good.

Thanks for support

i forgot to say that some applications doesn't work properly

example: "beep"  when i execute beep i hear no sounds, neither from speakers (audio card)
nor from internal pc speaker.

in kde environment kconsole doesn't beep too.
mplayer seems to have some problem using the alsa output, giving strange messages.
(using oss emulation works good, with the only bad sound quality problem)

xmms with alsa plugin works good without any warning or problem.

Did you enable CONFIG_INPUT_PCSPKR?

Then it's a mlayer specific problem.

sorry i can't find it! i searched whole sound system part of menuconfig
without finding nothing similar...

i suppose so too. i'll fill an mplayer bug.
however it seems that the problem is with IDE driver, when DMA is
enabled. Can the right team investigate for that?

It's in 'Input device support/Misc' section (by mysterious reason :)

This has nothing to do with ALSA -- you are probably not loading the PC 
speaker driver.

Hello,

Do you have DMA enabled for your hard disk? hdparm -d /dev/hdx
will tel you ...

disabling DMA fixes completly the problem.
of course cpu usage is very high without it.
i can't burn cd and speed faster than 4x.

so ide-dma related seems!

It's a known problem with this hardware.
Since the ALSA code isn't change, I suspect the problem is somewhere
else, e.g. in the IDE driver code...
