theconnactic posted a topic in General DiscussionAfter a painful waste of all my last weekend trying to patch AppleHDA for the Via-VT1705 codec of my motherboard, with the help of Mirone, a very experienced person when patching HDA is concerned, we had to gave up: we finally hit a brick wall, where no advancement was being done. The research we made for the patch, yet ending in failure, revealed a important caveat: almost all guides for binary and DSDT patches aiming a full working AppleHDA are meant for Intel chipset motherboards (there are in fact a few resources for nVidia chipsets). We AMD users have been left at the mercy of VoodooHDA development. While VoodooHDA surely works (in fact, i have to use it to finally have onboard audio), this is far far from an optimal solution: there are lots of reports of poor quality sound, noise and system instability. VoodooHDA, if it doesn't enable our HDMI ports out of the box, won't enable it at all, and Intel users on Mountain Lion can always resort to many DSDT edition guides for HDMI fix, even without working onboard audio. That's not possible yet for us AMD users: the overwhelming majority of the DSDT patches available in the scene today doesn't blend well if our motherboards. In ATI chipset-based boards, southbridge and northbridge schemes appear in a completely different manner. With Lion, the situation is even worse: the successful DSDT patch, by itself, is not enough - AppleHDA must be properly recognizing and working with the onboard codec. But then again, many AMD-based boards, specially cheaper ones, use strange codecs, for which no support is provided. We deserve better! So i think it's time to start AppleHDA and DSDT development targeting specifically our needs. My resultant after these days of hard work and research, is attached. It still fails to enable AppleHDA sound and HDMI audio, but at least it loads the kext, and both AppleHDA (HDEF) and HDMI audio (HDAU) appear in IOReg. I made this DSDT replacing the SBAZ@14,2 entry by Toleda's HDEF DSDT patch, but keeping the original address instead of 1B. I added also the basic discrete graphics edit by Toleda, and renamed another SBAZ entry to HDEF. Then Apianti of projectosx cleaned it from warning and remarks. Mirone also made some edited DSDTs, trying to help me to have native audio, but since his DSDTs didn't perform quite well, i decided to attach my own: DSDT.zip Mirone also made various binpatched kexts for my Via-VT1705 codec. Here's some links, if you want to play with them (all credits go straight to him, if some of them succeeds to give audio as is: he worked alone, and working hard, to "boldly go where no man has gone before"): http://cl.ly/1w0n2D3M1Y0A http://www.sendspace.com/file/nh8oc8 http://www.sendspace.com/file/7ji0tz http://www.sendspace.com/file/vvdzfj - his DSDTs are also attached in these links.

Let's start? Notice that it's not expected that any of this files works at all: they're meant only as starting ground for R&D, and as guidelines for what to try (or not to try). Many thanks to Mirone, Toleda and Apianti. Best regards!
