iSub back in action!!

I'm not sure if this is still a issue for anyone but here it is.
Please note: that I've only tried this on a PPC running OSX 10.5.7 and "NOT" an Intel. AND Backup before you try this.

The procedure is as outlined on, "Paul Tung's" post, back on May 17, 2006.
Topic : Possible iSub Solution in Mac OS 10.4.6!!
http://discussions.apple.com/thread.jspa?threadID=485373

1) Download the following files:
a) Mac OS 10.5.3 Update or Mac OS 10.5.3 Combo Update. I used the Combo.
(Addresses an issue with stuttering video and audio playback in certain USB devices.) - I should read the "detailed information" link more often!
http://wsidecar.apple.com/cgi-bin/nph-reg3rdpty2.pl/product=19138&cat=60&platfor m=osx&method=sa/MacOSXUpdCombo10.5.3.dmg
b) Onyx
http://wsidecar.apple.com/cgi-bin/nph-reg3rdpty2.pl/product=00059&cat=15&platfor m=osx&method=sa/OnyX.dmg
c) Pacifist
http://www.charlessoft.com/Pacifist.dmg

2) Install Onyx and Pacifist programs

3) Go to: Macintosh HD (Your HD) -> System -> Library -> Extensions AND "Trash" the following file -> AppleUSBAudio.kext
and enter your admin password when prompted.

4) Open the downloaded Update. Start Pacifist, read or click OK on "First Launch Quick Start" window.
Click Open Package and then select the MacOSXUpdateCombo10.5.3.pkg (under DEVICES in Sidebar menu).

5) Once loaded, go to: System -> Library -> Extensions -> AND single click: AppleUSBAudio.kext.

6) Click the Install Button - Top left. It will ask you to install, and click install. (Make sure Allow Admin Privileges is selected).

7) Once done, quit Pacifist and start Onyx. This process will clear the "older" AppleUSBAudio.kext is out of the system.

8) In Onyx, go to Cleaning and make sure System and Kernel Caches is selected. Also, select Core Files and Temporary files too.

9) Once done, restart the computer, and go to the sound control panel and set your iSub.

Thank you PAUL TUNG! and "LONG LIVE MICHAEL JACKSON"- R.I.P

OS X 10.6 Snow Leoprd & ISUB
Summary:
The Harman Kardon iSub is not always working on Intel Macs without the use of other USB audio hardware. It is NOT working on the latest Intel Quad MAC PRO but is on a Dual G5 under OS X 10.5.8.

Steps to Reproduce:
1. Plug in iSub into any USB port.
2. Check Apple System Profiler. Device is correctly listed in Apple System Profiler, but does not work, and does not have separate volume control in the SOUND Control Panel.

Expected Results:
Expected iSub to work in conjunction with internal speakers, external USB speakers, or with external non-USB speakers, as it should.

Actual Results:
Device is listed in Apple System Profiler, but does not work, and does not have separate volume control

Regression:
This bug does not occur on PowerPC based Macs, just on Intel based Macs. Tested on a Power MAC dual g5 under OS X v10.5.8, Power Mac G4 400 Sawtooth, Power Mac G4 867, Power Mac G5 Dual 2GHz, Intel Mac Mini 1.5GHz Core Solo, Intel iMac 20" 2.0GHz Core Duo, Intel MacBook Pro 17" 2.16GHz Core Duo, Mac Pro Quad 3GHz under OS X 10.6 Snow Leopard.

Workaround not working in Snow Leopard:
Attach another USB audio device (sound card, USB headset) and select that for sound output. The iSub and it's volume control will magically appear in the sound control panel. Once you select Internal Speakers or another non-USB output, the iSub and it's volume control will disappear, and will cease outputting audio.

Initially, for bug # 4590777, Apple had listed it as a 'duplicate' bug, so there was some hope of having this fixed. As 10.4.4 was the initial OS X build that shipped on the first set of Intel Macs, maybe 10.4.5 would remedy this. Then the updates kept coming. And still, it wasn't working.

Once 10.4.9 was released, I tried the iSub again on all my Intel Macs. Again, no dice. So I sent in another bug report for Apple to fix. I was hoping this would be fixed prior to Leopard's launch. To my dismay, I received the following email from Apple.

"Hello, This is a follow-up to Bug ID# 5061928. We have received the following update regarding this bug:
<GMT14-Mar-2007 23:41:32GMT> Vanaja Pasumarthi:
Engineering has provided the following feedback regarding this issue:
Unfortunately, we have had to discontinue the support for iSub for built in audio. This is behaves (sic) as expected. Please disable iSub on yellow machines for all configurations.

We have closed this report as resolved. Thank you for taking the time to notify us of this issue.
Best Regards,

This has been an issue for quite some time. As an owner of a few Intel based Macs, I'm disappointed that Apple has decided to discontinue support for their quickly emerging platform. It sort of goes against the statement from Apple that "Everything just works." Funny how the iSub does work in Windows Vista, however.

Please post this for the other iSub owners who might as well know this now instead of waiting even longer.

An iSub owner reply on using an iMic as a workaround. (this was before OS X 10.5/Leopard was released - see top of page for notes on iSub problems in Leopard.-Mike)

"I started trying workarounds (I found one that works!)
Here the setup, done with a pair of klipsches, an iMic and the iSub. First plug your iMic into your USB port on your Tower or USB Hub, Then plug your speakers in to speaker icon side of the iMic then plug in your iMic into another USB port or your USB hub. Check your Sound Preferences and you will have both of the Klispches and the iSub working!
(he later wrote)
I'm using the imic to insure I can use both my klipsch speakers at the same time I'm using the isub not one or the other. Adding another usb device only gives you the option on an intel mac to use your internal speaker on your tower and an isub. By pluging my speakers into the imic I have the ability to use and control the volume for both my external speakers and the isub.
-George H."

The isub issue is not fixed as of OS X 10.6 and the workaround does not seem to work either. Bob.

It is hard to compare the lack of driver support with anything from before the computer age but there would seem to be no question that a purchase represents a contract and that contract implies providing good faith updates. One might compare this to when a company must issue a hardware recall to make a device function properly. Indeed my iSub while perfectly sound mechanically is prefixally useless due to apples lack of support. Am I the only one that feels criminally ripped off. What about a class action suit.

Long story, but I got an iSub as a "gift" from Apple a few years ago. It worked great on my G4 eMac and then not so good on my G5 iMac. But when I asked two years in a row at the Apple Service Desk and also at Harman Kardon at MacWOrld in SF, no one could figure out why sometimes it would start up over modulating and as soon as I went into the Sound Control Panel it would work normally. Now with OS 10.6 and my new 21.5" iMac it does not work at all. I'm very disappointed that the engineers at Apple have not been able to get this subwoofer to work on their new OS. There must be more to it that we are not being told?
