Hi all.

I´m facing problems with 5.1 channels for my ALC888 codec.

I can configure 5.1 channel cause my system recognizes my 6 ports, I can set it to 5.1 and test all the speakers individualy, but when playing files from any player, it gets only 2 speakers working and in the test section all speakers works nice.

What am I doing wrong????
Is there something I should change???

Here are the links for images of my system config for 5.1 channel using Audio MIDI Setup.

You probably aren't playing that has a 5.1 source. Try a DVD with Dolby Digital 5.1 audio. Make sure to configure your DVD player properly. There are programs for Windows to take a 2-channel source such as mp3 music and create a 5.1 environment out of it, but I don't know about in OS X.

Quick question: can the 6 streams be interleaved live to the digital output using an aggregate device or is this only for redirecting multiple stereo streams to the analog outs?

HI. One small problem.
My channels are set in midi to 5.1. Test ok. But after playing some music or 5.1 stream, channels position will be changed.
Like: stereo will play RL RR, i restart player and plays on C LFE and next restart on FL and FR. For 5.1 order changes channels too.
Any fix for this?

ALC888 chip...

i dont use front panel connector, no pins are connected.
but in os X the sub+center jack is mute. while the rest of the connectors work ok. this leaves me with 4 channels out of 6.
is there any way i can enable the headphones on the back, change jack mapping etc?


That's the same situation and board as me, I guess if you follow Taruga's guide (attached below) you can manually edit the pin assigns.


I can attest to the fact that this technique works, I subsituted the front headphone Node ID for that of the orange rear output Node ID in the info.plist for AppleHDA.kext, and using the aggregate output device guide from this thread, I now have full fantastic 5.1 Audio!!!

(gigabyte EP45-DS4P mobo, ALC889a audio)

w00t!

All thanks to consolation & the helpful info of contributors to this thread!


Thank u all!

Thanks Consolation, I finally got 5.1 sound (which I'm a fan of so much :help: ) on my Hackintosh (the last reason I still needed Vista lol)

I'm using Realtek ALC889a soundcard on EP35-DS3R motherboard, and together with kexts from this post I got it working! I'm very happy :D thanks

Great Post! :blush:

Hello, I need help setting up my ALC888 with 5.1 channels. I followed a guide for Aggregate Devices and I set all the channels to their current speaker however I'm still getting 2 channels output from aggregate device. Any suggestion ?

Hi!

My goal is not having 5.1. I have two small speakers when i'm in front of the computer, and two large speakers connected to an amplifier. What I want is to have plugged in the small speakers and the amplifier through the rca cable (white/red -> minijack) to the rear cpu panel and choose in system preferences where I want to send the signal.

Is this possible at all? I have ALC882 on my motherboard.

Thank you!

I go through the add aggregate device and test the speakers, and it recognizes all 4 of them. But when I select the aggregate device as the system default, it does not play any sound back.

Any idea what I am doing wrong?

Thanks!

Thanks this is awesome.
Using MPlayer Extended I can get my stereo music and movies to play through all speakers :(

If you want to play music/movies through all speakers, follow this tutorial:

Which channels are you using for your setup? I had to assign one to my front case headphone socket to get 6 channels. If I used just the back sockets I'd get only 4 channels.


thanks for your wonderful solution. i use ga-ma78g-ds3hp, i meet the same problem what you had mentioned above(I had to assign one to my front case headphone socket to get 6 channels. If I used just the back sockets I'd get only 4 channels.). I think if there any way to use only the back socket to get all the 6 channels instead of always unplug it from the back plug into the front hole.

anyway, your perfect work give me a big hand, thank you.

Laik, I had that problem too, I get a "solution" using Jack (just google "jack for mac"). With it you can send any input/output from system or applications to another one. This way you can get a stereo music in itunes playing on 5.1 for example, just send the out1 of iTunes to system 1,3,5 and out2 to 2,4,6. And so on for the rest of applications.

this post is worth the weight of my pc in gold

success here!
ALC889a on GA EX58 UD5
with AppleHDA.kext and HDAEnabler.kext in S/L/E.
At first I had the same problem as nat

it wont let me select 5.1. how can i make it let me select it?

but the following solved it:

-Different bit/sample rates on channels, you have to make sure that each channel in the aggregate device is set to the same sample/bit rate.

Hi all.

I have my Lion working as posted here. I didn't use kextcache flag atm, so I got the audio kexts (ALC885_889a.kext ) in ChammyVolume/E/E and i patched applehda.kext in /S/L/E

Once it was working, under MIDI setup, I made the aggregate device for using 5.1 as i did on SL.
When i use configure speakers, every single speakers works when I set the right channel.

All working good for me!! Thank you for the usefull how to!!

Cheers,
D

P.s at first i thought something wasn't working for the grey sign appearing when i strike the keyb's volume keys. After some asking around, I remembered that's normal.
I've been stupid because i didn't try at all to play some audio and that stucked me for a pair of days.

EDIT 2:

All solved. I've forgotten that was normal!!!!
Using aggregate device the volume icon, when you use keyboard's volume control keys, it's always greyed.
When I play music or something, all works fine!

I leave the post for other users who could have the same "problem".
