From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:0.9.2) Gecko/20010725 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 drivers. Version-Release number of selected component (if applicable): How reproducible: Always 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, and exit. Additional info:
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 http://notebooks.hp-at-home.com/products/notebooks/specifications.php? modelNumber=n5470 http://www.douglasstewart.com/n5470.html (very similar notebook) http://www.deater.net/john/PavilionN5430.html

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 the device. (disable Plug and Play)
kernel drivers would be at linux-kernel@vger.kernel.org, or linux-sound@vger.kernel.org. You *may* try enabling ACPI in your kernel, but I don't think the ACPI configuration infrastructure is complete enough for this yet.
