Subject:   sound on Intel D815EEA motherboard
Message-ID:  <80709.987326458@thrush.ravenbrook.com>

I have an Intel D815EEA motherboard <URL:
http://developer.intel.com/design/motherbd/ea/ea_inst.htm>.  This has
one built-in audio system (ICH2) and another optional one
(SoundBlaster).  I have the version without the SoundBlaster.

I want to get the audio working; it's not currently supported in
-CURRENT or -STABLE.  The chip is called the ICH2, PCI vendor ID 8086,
device ID 2445.  At boot time the PCI probe sees the device but can't
identify it.  According to Intel it's AC97 compatible.  I have the
Linux driver code for it (i810_audio.c).

I'm prepared to put in some coding time.  Is anyone else already
working on this driver, or shall I start from scratch?  If I should
start from scratch, presumably I should clone one of the existing AC97
PCI drivers, such as es137x.c or cs4281.c.  Can anyone with experience
of the sound drivers advise me here?  Is this even the right mailing
list?
