Description of problem:
I have an ES1988 Allegro-1 card built into my laptop. When I run
sndconfig, it says it found a PCI card and identifies it, then it
says the card is supported, but mine is disabled. It recommends
setting 'PNP OS' to 'No' in the BIOS. My BIOS doesn't give me that
option. At the ESS website, they say their cards are all SB
compatable, but I don't know how to tell sndconfig to use the SB
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. run sndconfig
Actual Results: It gave the messages as described above.
Expected Results: It would install the right modules, give a good message,
Can you post the output of lspci -vn?
I have another notebook with the ES1988 Allegro-1 with the exact same problem.
HP Pavillion n5470 Notebook
(very similar notebook)

Your device is not enabled. You need to frob the BIOS or machine somehow so it has
an IRQ assigned to it. (If you look at the lspci output, the device has IRQ 0
assigned to it...)
We do not have the BIOS options to a disable Plug and Play OS, or to manually
assign resources to devices. We need a pure software work-around for this
problem, or else sound will not be working on many of these notebooks.
Can you at least tell me where to find a mailing list, sites or developers of
Linux sound drivers? It is currently IMPOSSIBLE to use this sound device on
these many new notebook computers due to the lack of the BIOS option to enable
(disable Plug and Play)
kernel drivers would be at firstname.lastname@example.org, or
You *may* try enabling ACPI in your kernel, but I don't think the ACPI
configuration infrastructure is complete enough for this yet.
