Well, this isn't the mailing list. That would be here
, and I suggest sending an email there (the devs don't usually check the forum). That said, I'm sure this forum will be happy to help too...
As for the ids, the trick is that hdaudio_codecids.h has the "codec_desc_t codecs" array used to identify the codec. Pci ids will require changing oss_hdaudio.c and
the ".devices" file (the latter is all too easy to miss). If you could attach your modification perhaps we could look at them too... Also I suggest posting to the sourceforge list as well.
