chrs2021 Posted June 23, 2006 Share Posted June 23, 2006 chris can you post your latest code that you compiled with? i didn't compile any code i was using Dopefishes build, and it works pretty well except the fact that it crashes when you load garageband and anything that tries using the six channel mode, also when you play your first 5-10 sound file its choppy then after its fine, i even changed the mode from 44100.00Hz to 48000 and it still ran fine. also i fail to mention that i have usb mic so i proablly didn't stress out the driver enough... other than that the driver is superb. But i still want my garage band. so if there is anyway to disable the 6ch thing pleease let me know. well for a while the 48000hz work now it KP's but for now @ 44100Hz works fine so far.

thedopefishlives Posted June 23, 2006 Share Posted June 23, 2006 Hm. Well, the 6-channel code is just as ripped out of the Linux driver as anything else, but I don't have 6-channel capability on my lappy, so I can't test it.

EdFlyer Posted June 23, 2006 Share Posted June 23, 2006 go to system preferences -> sound -> output and tell me what your name and port are  mine says name: Line Out port AC97 Audio (PCM)   i'm pretty sure hat's why I don't here sound, but I can see in the console that it is laggy and that the perform audio engine stop is getting called.

EdFlyer Posted June 23, 2006 Share Posted June 23, 2006 I have internal speakers. They are not connected to line out however. My hardware is working because I can hear the pop as the chip turns on, however, there is no sound being outputted to my speakers, headphone, or microphone ports (i checked them all just in case.) Â its odd.....i'm trying to figure out why its happening that way.

Â Ed ? Dope ? anyone Actually, I put in a lot of debugging stuff using IOLog instead of DebugLog. I'll go back and change a lot of that as soon as I can confirm that everything is working properly and I get a coupla other bugfixes done, which will probably be later today. I have a major project that has to be finished in Linux, but I'm almost done with it and will be able to answer Ed and you today.

thedopefishlives Posted June 23, 2006 Share Posted June 23, 2006 On my system, the driver exhibits some strange behavior, playing through buffers too fast (i.e. the Chipmunk Phenomenon), and also very entertaining kernel panics after a few minutes of usage. Looks like I got a lot of debugging to do.

SkylerF Posted June 23, 2006 Share Posted June 23, 2006 Just as a refresher: whats the process for installing the latest build? Link to comment https://www.insanelymac.com/forum/topic/10903-ati-ac-97-sounds-sb400-effort/page/10/#findComment-134079 Share on other sites More sharing options...
EdFlyer Posted June 23, 2006 Share Posted June 23, 2006 download the latest attatchment posted from dopefish.  extract it  go into the build/devlopment directory and drag the AppleAC97Audio.kext file to / directory (usually on the left where your hard drive icon is)  then open up a command prompt  type sudo -s type in your password, hit enter  then type cd /System/Library/Extensions/ cp -R /AppleAC97Audio.kext . chown -R root:wheel * chmod -R 755 *  and then reboot your machine  (with -v if you care to watch the verbose stuff)  And then you can test it and say what happens  kernel panic traces would be nice if you could get them (i don't remember how to get them right now [google is friend])   and that's about it.  Oh, if you type "ATI Audio SB400" in google, we're the first one to come up.

chrs2021 Posted June 24, 2006 Share Posted June 24, 2006 How do you change between 48000 Hz and 44100 Hz? In applications go to the utilities folder then double left click on audio midi setup, on the front page it allows you to tinker with audio properties. which reminds me can't the AC97 go lower than 44100Hz -16bit. cause that might have something to do with the driver...., another thing would it bepossible to have it putout to another log file besides system.log and ed i think inorder to veiw kernel panic logs you need a real mac. because the method of logging the panic involve the nvram something normal pcs don't have.
