ONKYO SE-90PCI also uses WM8716, so maybe they use the same wiring for both cards and WM8716 is the DAC used for stereo output on both cards. do you think that ONKYO will provide the wiring information for both cards if we ask them for ? because the alternative is to use digital ohmmeter to reverse engineering the wiring and it's very hard, that is why i have problems with ONKYO SE-90PCI ... I've attached EEPROM dump and patch for the dump program. Personally > I think it should be included in envy24ht(4) and users can extract > that information with sysctl(8) interface.

BTW, if we need EEPROM information to initialize the hardware why > hardcode cfg_table for each hardware model? most of the Envy24HT-based cards have not valid EEPROM data or even empty EEPROM (that contains only PCI SubVendor and SubDevice IDs), good examples for such cards, are all cards made by Terratec and Audiotrak, so their init values are hard coded in their windows drivers and in this case all EEPROM related routines in the driver are worthless. however if the card has valid eeprom data that can help to find the right wiring and also can be used to initialize the card. > >On 10/28/06, Pyun YongHyeon <pyunyh@gmail.com> wrote: > > >> > > > >> >On Sat, Oct 28, 2006 at 02:43:53AM -0500, Nikolas Britton wrote: > > >> >> Hey Konstantin, I think I found a bug in the code.
