Andras Kenez Posted March 4, 2006 Share Posted March 4, 2006 ATI sothbridge sound did not supported yet On WindowsXP ATI use Realtek ALC 650 like VIA, and some supported Intel wich has Darwin driver.... Is it possible to rewrite AC97 source to support ATI south bridge ?

Andras Kenez Posted March 6, 2006 Author Share Posted March 6, 2006 I found Linux ATI, VIA AC97 source....... http://www.linux-m32r.org/lxr/http/source/sound/pci/ Link to comment https://www.insanelymac.com/forum/topic/10903-ati-ac-97-sounds-sb400-effort/#findComment-70169 Share on other sites More sharing options...
hell Posted March 7, 2006 Share Posted March 7, 2006 since mac os x uses bsd kernel, I think bsd ati ac97 source is more useful http://www.openbsd.org/cgi-bin/cvsweb/src/sys/dev/pci/ Link to comment https://www.insanelymac.com/forum/topic/10903-ati-ac-97-sounds-sb400-effort/#findComment-70290 Share on other sites More sharing options...
EdFlyer Posted March 7, 2006 Share Posted March 7, 2006 I've been working on the ati sound, 43701002. So far I've gotten the chip to inizialize, but I haven't gotten past that yet. The driver loads, but doesn't connect to the sound. I"ve been modifying the AMDCS5 something driver that comes in the 10.4.3 sources, AppleAC97Sound. If you want I can post the source code that i've gotten so far, but I can't guarantee that it is correct. I am still learning what all the code does. I've been doing this by comparing the methods in the bsd driver to the mac os x driver. Hopefully I can get farther today.

EdFlyer Posted March 7, 2006 Share Posted March 7, 2006 So far I've got chip initialization, a one succesful codec read, but then a timeout. and the driver closes. Im working on the proper codec code right now.

b.megin Posted March 8, 2006 Share Posted March 8, 2006 would be great if you could fix it.. have the same audio hardware here... tried almost everything, but audio is the last thing not working at all on my acer aspire 5012 thx... d. specs: acer aspire 5012 laptop AMD64 3000+ ATI Mobility x700 (working although some mouse tearing) ATI SB400 AC97 Audio (not working yet) Bluetooth, LAN (working) - Wireless not tried yet. running OSX 10.4.5 (myzo prepatched dvd) and WinXP (w/ bootitNG as bootmanager - recommended!)

EdFlyer Posted March 9, 2006 Share Posted March 9, 2006 So far: Chip Init, it reads the 3 codecs but only attaches one. driver still crashes the System Preferences -> sound page. I think the problem is in the codec attachment. I am working through that problem right now. Hopefully once that's done I'll be able to have sound, not sure though. As far as a website, I can have a page up next week, once I get back to school. If anyone else has experience with C++ and Mac OS driver development pleae let me know if there's anyway you can help.

I had started to develop one too but I had to quit because I was too busy. Which Codec are you using? Is is the Realtek ACL250? Mine is. I have device ID 4370 also. My problem was getting the Audio Engine streams working. This is a good read: http://developer.apple.com/documentation/D..._section_1.html This is certainly a fun project with learning possibilities.

Brandon2004 Posted March 18, 2006 Share Posted March 18, 2006 Could someone please try this my os x install went down when I tried to upgrade to 10.4.5 this is a compiled kext from darwin Check the macgirl download I have the compaq v2570nr and on xp it uses the conexant codec so I think this might work if someone could give it a try Link to comment https://www.insanelymac.com/forum/topic/10903-ati-ac-97-sounds-sb400-effort/#findComment-78038 Share on other sites More sharing options...

digicide Posted March 18, 2006 Share Posted March 18, 2006 Brandon... That kext has been around since november, lots of people have tried it... I've tried it.... unfortunately the ati ac97 is different enough that it doesn't work for us. That's why Mr. EdFlyer here is working so hard trying to build one.

EdFlyer Posted March 18, 2006 Share Posted March 18, 2006 Im using the AC97Audio Framework in an attempt to get the audio to load, but the process is slow, as this is the first non-education (done in school for class) c++ project I've worked on. I just got back at college, so the development will slow down once school work picks up. I'll have a website up soon, so hopefully there can be more information sharing there. Out of curiosity, can anyone find a page with information about the sb400, like its registers and stuff; a technical document from ati. Any and all information I have will be useful in this endeavor.

EdFlyer Posted March 19, 2006 Share Posted March 19, 2006 http://www.realtek.com.tw/downloads/downlo...?keyword=ALC655 this seems to contain some information about the hardware that would be useful in implementing a driver. Scousi: can you send me the code you had done for this? Maybe I can finish it. Let me know.
