No sound 7500/G4 375 10.2.2 |

I am having a heck of a time with my beefed up 7500. I can only get sound after booting and before I run any other applications. This is true for Quick Time, iTunes, and any system sounds. Any ideas out there? Andy |

I have seen this problem on my system running the Acard ahard 66, AND on my system running an Adaptec 29160N, so it is NOT just an IDE thing. As mentioned it also appears a problem for people using "supported" hardware, so probably not just an Xpostfacto issue... I wonder if using a digital audio interface such as imic, or the Maudio audiophile card might change/fix this? Marty PS Really annoying. |

Aside from two knowen problems.. 1) The sound manager problem fixed with the sound manager update or by DLing the latest full installer of quicktime, and 2) ATA or really fast scsi cards overwhelming the PCI bus. This sound plays for a little bit and breaks up is also the first thing I'm seeing go wrong with overclocking a sonnet card (at 880mhz). The next thing is disk images failing to mount due to checksum verification (at 900mhz). Has anyone experencing this sound problem tried to back off 20 or 50 Mhz in CPU speed? |

This also fixed my problem on my 7500/G4 800 10.2.2 I tried to add an IDE hard drive using the SIIG ATA 133 (Acard in disguise)PCI card and the sound would never work. I switched to an ATTO UL2D card and two Maxtor 18G U160 drives and everything just about back to normal. Sound is still very low but adjustable in iTunes. Will be trying external powered speakers next. iTunes still stops playing at times but all over the discussion boards at Apple, everyone seems to be having these problems. I guess new hardware is not always the answer when our vintage systems still have life. |

I fixed the sound problems on my 7500 sby completely removing my ATA66 card and switching to a SCSI hard drive. Sound has been rock solid ever since. |

This is a reasonably common problem--unfortunately, I haven't seen it on any of my machines, so it is difficult to track it down. |

I have an Acard ATA 66 adapter and a PowerLogix G4/533 ZIF upgrade, running at 420MHz, due to motherboard bus speed issues. I have external Logitech Soundman speakers, which are externally powered. I can get just a tiny bit of sound for a little while, then it stops. In System Preferences, after a reboot, I can change sound alert sound choices as many as five times before sound cuts out completely. It SURE would be nice if I could get some sound - the transition would be complete. Since I got L2 cache running, my PM 7500 is twice as fast as without it, making everything *quite* usable. All I need is sound. |

Perhaps the Carbon sound manager update will help? |

I, too, am having these sound problems; the carbon sound manager update didn't seem to help. iTunes still cuts out after a few seconds. 7500/G3 450, 10.2.2, Sonnet ATA 66 card, 60G IDE hard drive. |

Quicktime 6, both the update and the one included with jag just sucks at playing sound with a low sampeling rate. 11khz, 22khz, monophonic stuff it will play badly then stop making any noise at all. When it can no longer play sound no other software can generate sound until after a reboot. Apple has put out a few knowlegebase apologies about this but don't appear to think fixing it is something worth their time. I've had the problem happen for some 44.1KHz sounds as well though they don't mention it. If we were dealing with mac OS9 I would say sound manager has problems. I don't know what the OSX equivalent is. Recent versions of Mac OS 9's sound manager have had odd troubles with G4 upgrade cards. A solution might be to upsample the system sounds or whatever you are starting out with. I tunes playes fine for me but I'm doing it from a network (itunes is on a remote SCSI mac with 10.2.2). |

On my PowerWave w/ XLR8 G3/500 running 10.2.1, iTunes will happily play audio from a streaming site, but will randomly stop when I try to play from either the internal SCSI or an external OWC FireWire drive via an MacAlly FireWire card. It acts like a buffering problem as it fails with strange audio artifacts, like playback is confused about the samples. iTunes continues to display running time and seems unaware that it's not actually playing. If I stop it and then start it again, playback will resume for a time. This is very frustrating as I'd like to use this Mac as the house jukebox using netjuke . I'd be happy to help troubleshoot and hopefully come to a solution. |

I have no ATA hardware and I get sound just fine, although the volume level seems to be pretty random. I can play iTunes just fine but I can't record. It locks up. So far, the ATA guys have problems playing music in iTunes with it locking up and the SCSI guys have problems recording, it seems. As for no sound, there is a problem with the volume control. Try attatching a stereo system to your line-level out on the back of the case if you have an AV Mac and see if you get sound out of that. That works for me. |

I have the same problem with a PM 8500. I can, as an example, listen to iTunes all day as long as there is no disk I/O activity (not even a screen saver). There are many comments about sound problems posted on this board. Perhaps if all that information were brought together we could find a solution. My current best guess is that using an ATA adapter is at fault. I have a Sonnet Tempo ATA 100 card, which otherwise works great. Other than that comment I am at a loss to make other suggestions because I am at my technical limit. I would , however, help with testing any fixes. |
