Driver for Philips Acoustic Edge (PSC 706)

Hi. Can anyone tell me if there exists a linux driver for the Philips Acoustic Edge (PSC 706) sound card? Or if someone is working on one?

If not, I'm a fairly resourceful and clever programmer. And I have the card in question. How does one get started creating drivers for hardware like this?

thanks,

Could you please supply a lspci of the sound card.

You can start of by finding out the chip on the sound card and getting the datasheets for it. If the chip supports or is supported by some current drivers, you could make the appropriate additions to the supported cards in the particular modules (add Vendor/PCI IDs) and see if it works. Otherwise you could start work on a new driver :) It might be an idea to read through a couple of drivers and see how they do things. For additional help regarding kernel hacking in general, check out www.kernelnewbies.org and the mailling list is at [email protected]

Good luck, and happy hacking :)

Thanks for your response Zwane. I did as comprehensive a lspci as I
could do and got the following results. If you can direct me to a working driver commercial or otherwise I'd be much obliged.
