Hey guys,

My HP Presario B1800 notebook is bultin ICH6 AC97, but no sound. Kernel load the AC97 driver and I can change the output volume well. Everything is good, but no sound!.... sad.gif

I found an intresting file 'com.apple.audio.DeviceSettings.plist' in /Library/Preferences folder. Anyone can post this file to me? I think ICH6 and working version is best. I try to replace it with a 'working version'. See what would happen; here is mine:

Yes, I tried. I only got '2ch-16ch' option. At Configure Speakers, only 'stereo' channel 1, 2. no channel 3 and 4. Too bad! But thanks anyway.

Still hope someone can post your working om.apple.audio.DeviceSettings.plist file to me..... biggrin.gif

By the way, I can not change the master volume slider within 'Audio MIDI Setup'. It's disabled. Anyone got the same problem?

I have the exact same problem and have been pulling my hair out for a week about it. I too have a card that shows up under the ICH6 section. I don't think any of us who have these cards have had any luck. *shrug*

Mine works. It won't output sound via the internal speakers, but at least it works w/headphones. "SoundMax" or whatever on a Compaq DC7100 SFF (915G chipset).

Hmm.. more luck that I have with it. Mine does not work out of the headphone jack either..

In the Sound is it listed as Line Out for you or does it actually say Headphones?

My mic works though. I recorded through it then played it back on a different machine and it worked. I wonder where it is routing my audio out to.

I'm on a Gateway M250X laptop.

It says line out...or it might have just had speakers. But when I test a screen pops up where you click on each speaker to make static and both sides worked.

In the midi panel, I remember one of the PCM options had 2 I could pick from, and one of them enabled sound whereas the other didn't. Not at work now so I can't take a look at the screen, though.
