Mirone Thx for your fast reply. In pc, I connect my "Martrix USB SPDIF" It will show up a new speaker output device. Also I have try connect to my friend mac book air(10.8), It also have a new device can show up in sound preferences output. I have search internet to get some infomatiaon, some people can show out a USB unkown Digital out device. I'm the first time to patch the applehda.kext, So I think it maybe something I missing to do. when i dump the codec file, I get 2 file, One is Cx20590, the other is Intel. I just have patch the cx20590 codec file, but I can't see any "Jack Type" in digital-out. When I look the Intel dump file, all the "Jack type" show in digtal-out . So I think that maybe my "pathmaps" problem. In My layout12.xml I just can see CodecID"0", Do I need to add a CodecID"3" for my Intel codec? Also some people say that, If miss output device, It may cause by wong binpatch of the kext. I just patch if use the "10ec0887" by the script than replace my codec to the file. But I don't know I do it right or wong. Hope U can teach me, how to do!! Thank you!! Codec dump .zip
