I tried looking at the relevant info from the corresponding kernel extensions on mac os X. The codec has "Vendor Id: 0x10ec0885" so the relevant part of the info.plist on mac os X reads MicAttributes 28 MicInfo Sampled on rising edge NodeID 39 PinConfigDefault 2426405136 Which tells me nothing. In particular I don't have a node 0x27=39 (at least not that hda-analyzer sees) so it's not surprising that if I send the corresponding verbs to set_config_default I don't get anything. Also, I don't see how setting the pinconfigdefault could affect my not having the mic working (anyway I tried setting those pinconfigdefaults that put the node as a fixed mic on all nids 0x19-0x1c to no avail) As for the sampled on rising edge, I don't know how to use this info. any ideas? Thanks, R.
