8500 Sound |

Sound doesn't seem to work with OS X (10.2). It works fine in OS 9, but sound playback is either choppy and unlistenable or (more often) non existant. I have a Sonnet 700mhz G4 upgrade installed, and the system is fast and stable otherwise. Any ideas on this? |

I go 8500 RCA out to an old Commodore 64 monitor and use the volume control on the 64 to increase volume. I have been using the 64 monitor for years as a second monitor - since it is a special hi-res NTSC. Thats how I fixed the sound prob. |

I had the same question a few threads ago. As of right now, I am saving my pennies for the M-Audio card. I also hear rumblings about drivers for the SoundBlaster Audigy in Panther, but who knows if that will show up or not. I use an Audigy on my PeeCee and I love what it can do since most of the processing is done on card, freeing up the processor and pci bus for other things, critical for our old world machines. In the meantime, external speakers, and OS9 for recording, with NO sleep...... |

This is my problem with the sound on my 8500, Sonnet G4 800mhz, 640meg, Radeon 7000. OS 9 All configurations: perfect sound. OS X.2 G4+on-board video+(1)monitor (No PCI cards): no volume control, otherwise perfect sound. OS X.2 G4+Radeon+(1)monitor: No volume control, stuttering and finally permanent loss of sound. (PCI issue) OS X.2 G4+on-board video+Radeon+(2)monitors: No volume control, stuttering and finally permanent loss of sound if crossing back and forth between monitors. OS X.2 Radeon+on-board+ExtremePCI+(2)monitors: No volume control, otherwise prefect sound, just don't change screen resolution (this sometimes happens when a monitor is put in sleep mode) I also tried some other PCI cards and found that high levels of data traffic kills the sound. Seems to be an issue with the speed and width of the PCI bus on these machines and the the way OSX expects the base hardware to function. Any attempt to unload the sound KEXTs and re-load them (hopping to reset the settings) causes a kernel panic. An earlier post of mine referred to ExtremePCI changing PCI settings, but after closely examining the source code I discovered that I was wrong. All that it is is an apple script that changes some coregraphics.framework settings. These settings off-load much of the graphics drawing (Quartz Extreme) to the video card thereby greatly reducing the amount of data on the PCI bus. Any Comments? Suggestions? |

I've been struggling with no 10.x sound forever with my 8500/Sonnet G4-400/ATA- 100/40G HD & now I have no more loss of sound since my speakers were connected to the iMic plugged into a USB card (running 10.2.6). |

Sound works on my 8500, input and output. It has a Sonnet G4 800MHz, a little less than 800MB of RAM, Znyx 100base-T ethernet, Adaptec DuoConnect USB/FW, and Radeon 7000 graphics card. My drives are either SCA or 68-pin SCSI, and I have a Pioneer DVD-115 w/ IDE-to-SCSI adapter. Only problems with sound are: master volume doesn't work; if I put my display to sleep while sound is being used, it gets cut off. Workarounds are I connect external speakers to my sound out port and click on mute within OS X. Muting sound doesn't have my system's startup sound play at its maximum. I never put my display to sleep. |

I can confirm having the same sound problems starting with 10.2.3 (or 10.2.4 ... don't remember) with a PowerLogix Z-Force and an OWC CPU. No ATA/IDE drive at all, so I suspect that this is not the real problem (PCI cards could be, following other posters) and, in my case the sound problem worsens with a G4 CPU : sound stutters immediately, as opposed to after some hours with the G3. Since it appeared after a Jaguar update, may be our MacOSX guru could do something about it in the next version of XPostFacto (hint .. hint), but i'd like to see this correlated by other posters (which exact update broke the sound output?).

I also have a Sonnet (400 MHz G4) and my iMic won't work for output. Installing the external speakers to the Mac headphone jack (PowerMac 7300) works fine as long as I use the volume control on the external speakers. |

This topic seems to have become perrenial. Nothing I have seen suggested in this forum has yet resulted in consistent, dependable sound playback. Switching to earlier .kexts, using iMic, enabling PCI Extreme (although that did help a bit). Nada. I don't use ATA/IDE drives so that's not it. My sound problems started with later versions of Jaguar (10.2.3 or 4 +). OS 9 & QT both seem to be implicated. One thing I'd be curious to know: is this just a problem with Sonnet cards? Maybe it's just my imagination but it always seems to be people with Sonnet upgrades that are inquiring about this. Sure wish the Forum was searchable. (But that's another post.) It's not mission critical for me, just annoying. Still, hope shines eternal, maybe Panther will fix it.... |

For the above reason and the fact that I have many bad experiences with ATA/IDE drives, I have stayed all SCSI but do have to use external speakers to have volume control, since there is little or no support for the Old World Machine sound chip set in X Hope that helps Jim |

People w/ IDE HDs tend to have this problem on these Old World PCI Macs. |
