Howdy, I'm having trouble getting sound to work with FreeBSD 4.8 on a Compaq Presario 2500 (specifically a 2529CL). Has anyone had any luck with this laptop? According to the service manual both audio and modem functions are handled by this chip: Conexant Smart AMC CX20468-21. A number of other HP/Compaq laptops use this same chip as well (**I've appended a list below). The fact that audio is handled by the same chip as the (win) modem doesn't bode well. In hopes that this chip's audio functions somehow (independent of the modem functionality) emulate Soundblaster hardware (or Neomagic, etc) I've tried pretty everything I can think of, including: * loading (via /boot/loader.conf): pcm, sbc, neomagic, ess * building a kernel with 'options PCI_ENABLE_IO_MODES' * building a kernel with 'options PNPBIOS' All indications are that this is in vain. Here's some links: * Product site for Conexant chip -- http://www.conexant.com/products/entry.jsp?id=159 * Company that has linux drivers for some Conexant audio/modem chips -- http://www.linuxant.com/drivers/ I'm now struggling to cope with the realization that my new (okay... refurbished) 2.5Ghz laptop might not be able to play my mp3's !! (grrrr) Thanks for any and all help! Charles **List of other HP/Compaq latops using the Conexant Smart AMC CX20468-21 audio/modem chip.
