OK - it's a total shame no-ones got a clue about this. Since April, you've probably done something - like get another soudcard or replace the laptop or something, however, you didn't say so here so I'll have a shot if you like:
There is a hint that the soundcard driver may not be functioning properly or may need something else.

Talks about IRQ's. IRQ 11 is normally used for SCSI host adapters and, of course, pci cards. There's no real problem there. You could try assigning your different pci devices to different (otherwise unassigned) IRQ's to see what happens. This has been known to help.

This thread follows a discussion about the cs4281 driver - how it may need a patch. You could try recompiling the module and again looking for the soundcard.
However, it is likely that your soundcard is uckfayed! On old machines, the possibility of hardware failure should be considered. It seems unlikely that the drivers in windows and linux should both fail in the same way.
You can look up possible replacements via online stores and check them out against the HCL listing here (top of this page, click the menue headed "HCL" and follow your nose
)
You can also search "soundcard" in the laptop & handheld forum for discussions - you're looking for cards that are working after 3-4 posts (since this suggests user rather than hardware trouble). Or you can search for those cards you like...
Why you may not have received a reply...
Well, if you go look at the very first message in the first thread you will see a bit about how to post questions in this forum. Compare what they say with your listing - you actually compare well against other posts on this board however, so this cannot be the whole story. You did, for eg, supply dmesg and lspci output
It could have been because nobody could see a solution other than to replace the soundcard and this already had a standard answer (via HCL) - though I think this may be a bit callouse.
Though you did shoot yourself in the foot a bit by posting to your own thread before anyone else... this removes you from the "zero replies" list - a vital part of getting replies. Once you're off this list, the only way anyone will know about you is if, like me, they stumble upon your post in a search. OTOH: the longer you are on the zero messages the more likely someone will reply out of curiosity
(Something like £3 (bout 4-5 euros) ).
