How Can I use All channels of ALC889a to have 5.1 surround? - Page 3

Xenophage · #21 11-06-2008, 07:27 PM

OK - I just did a test. I have a 4-channel (Quadraphonic) aggregate device defined in Audio MIDI Setup using the green and black plugs. I selected this as my default output in System Preferences. It is true that System Preferences does not show any volume slider for the aggregate device. I'm not sure why, but that hardly matters, since the volume is usually able to be controlled from the application playing the audio.

I then opened an MP3 in Quicktime Player. I then went to Windows > Show Movie Properties. In the resultant window, I selected Sound Track, and then Audio Settings, to get to the list of channel assignments.

I then plugged my earphones into the green plug, and played the file. It sounded fine. I then switched right and left channels to right surround and left surround respectively. Now I heard silence. I then plugged my phones into the black plug, and lo-and-behold, the sound was playing there, as expected.

My aggregate device works perfectly, and I now have the ability to play quadrophonic mixes (Dark Side of the Moon, here I come...). I fully expect that if I get the headphone output working, I'll have a full six channels, and can assign them properly for 5.1 output.

I'm not sure what you're doing, exactly, but I'm having success.

I didnt try quadraphonic with your kext but now I cant get workingwith your kext.

LS8V14 kext is working now but I couldnt get success with quadraphonic.

I can only get to aggregate device I just select speaker and line out put but I couldnt get sound 4 ch. only 2 ch from speaker and green one.

can you send you screenshot for aggregate device settings and sound pref.

thanks for help

can you also upload screenshot of Audio (built-in ) screen from "more info" window.

By "more info" you mean System Profiler? It says "No Built-In Audio" even though it all works anyway.

The screen shots are attached.

yes it is same with me. that's interesting, my audio (built-in) shows the details but it does not work

(((

do you know how can I debug or do something.

OK, try this. It's another version of my hacked AppleHDA kext, only instead of putting ALCInject inside, I put HDAEnabler in there. Now, not only does it work for me, but my System Profiler shows that there is audio hardware installed!

Remember to remove all other ALCInject, HDEnablers, etc... and clear the kext cache, repair permissions, and all that good stuff...

OK - I've been digging further, and I've discovered several things;

• Taruga's patcher application was made with Platypus - a script wrapper.

• It contains an ini file, which has variables pertaining to "lineout1," "lineout2," and "lineout3." #1 is set to on, whereas 2 & 3 are off.

• The 889a codec dump I found contains nodes for the orange and grey jacks.

All the data seems to be there, but running the patcher app only gives the results we've gotten so far. I tried changing the ini file to enable 2 & 3, but the patcher did nothing different. If I had any idea what the script was doing, it might be possible to force the issue, but alas I have no clue.

So, all the data and ability to get the remaining outputs working appears to be there, but it just won't work. I'd either need the source files for the patcher (and even then I have my doubts,) or for Taruga to get back in the game.

yes, you are doing something

there is interesting thing. in this time , kext loaded but the jack is not recognized.

I am sending System profiler screenshot.

I think there is a tutorial about the patching HDA.

we should look at Taruga tutorial and I had found another guy , I think in netkas forum. but I didnt understand what happens.

I will look at again and try find then I will share with you the URL of page.

Xenophage · #29 11-07-2008, 02:03 PM

Odd that your System Profiler shows two devices.

At netkas - do you mean this thread?

I've read it as well. It's definitely another clue to this whole mystery. I'm planning to play with these ideas today, as time permits, and see where they lead me.

nexusmac · #30 11-07-2008, 10:02 PM

yeah this is.

yes I se two driver, I am thinking that one of them is graphic card Audio.
because it has different pc id.

I hope you will find the solution. for these day I am busy then maybe tuesday I will be totaly free.
