I have had a couple of responses from people like me, no sound when another app is opened up. Is there a solution? Or are we SOL? Andy |

Ok, after a few tries and several hours of searching (How many threads -are- there?) I found that (for me at least) using a hack called "PCI Extreme 2.1" [http:// pages.cthome.net/zacks/] fixed my sound issues, however you need a (PCI || AGP) Radeon card. What it does (if you don't know) is activates Quartz Extreme for PCI and AGP vid cards. I don't know what this has to do with the sound, but it may adjust some of the PCI interupts. The best part is that PCI exteme comes with source code so one might be able to find a clue hidding in there. The author claims that the downside to this hack is that it slows down DVD play back (down to 50%) and - causes- lost audio in DVD play back. To mikem17: Get PCI extreme and give it a shot. I glanced at the source code and does do some tinkering with PCI but I don't know what yet. You will need a Radeon for the QE but might not need it to fix the sound issues. narratordan@earthlink.net |

I haven't re-read thru all the posts of this very long link. But I would like to summarize what I think is the current state of things: Problem is with 7500 and look-alikes (7300, 8500, 9500, 8600, etc.). Problem does not exist or is much milder (just stutter, sound not killed) with 10.1.5. Problem is severe with 10.2.x (cuts out completely after first stuttering audio). SCSI, motherboard SCSI or other fast controller, is not immune (far from it), but playing from IDE or Firewire seems to more easily cause the problem. Manifestation: Playing a challenging stream that causes audible breakup, causes the sound to completely get killed until reboot. Work around: Griffin iMic or other USB-based audio I/O seems to help quite a bit (but I did get the iMic to cut out once or twice). |

to narratordan: I agree with your conclusions. I can add that I tried an Adaptec 2940UW card (which works after OS X is installed) to use with an extrnal SCSI drive. As soon as I accessed the external SCSI, sound quits, just like my ATA drive on the Sonnet ATA100 card. The PCI bus is the common item. I wish I had a solution, because otherwise the 8500 is very stable. |

I've been searching for the solution to this same problem. My Mac (8500 w/ 800mhz Sonnet G4, 640Mb RAM, 3 SCSI disks; 1 for swap, ATI Radeon 7000) loses sound everytime I use it and must restart to regain audio. I have managed to track it down to a PCI issue and these are my reasons: My tests: No cards in the PCI slots, on board video, perfect audio (in/out/etc) ATI RAGE in slot (1||2||3) sound dies. ATI Radeon 7000 in slot (1||2||3) sound dies. Using two monitors, one on ATI and one on built-in, I can cause the sound to cut out and die. If -all- activity is on the monitor attatched to the built-in video, sound will continue to function, however the moment any thing is moved to the second monitor which is on an ATI (Rage or Radeon) video card, the sound will sputter and die requiring a reboot to restore. Repeated all tests in OS 9.x and OS 8.6 sound worked fantasticly, no issues. After these tests I concluded that the issue was somewhere in either the ATI cards or the OSX core audio and hardware abstraction API's. Now that I have read this thread in the forum, I feel that the issue is somewhere in the PCI routines. I'm going to search these forums some more to see if there is more on the issue. NarratorDan |

OK, the plot thickens.... I have an 8500 (820-0752-A), Sonnet ATA100 with a Western Digital 40 GB HD, 768 MB RAM, Newertech G4/400, 4 GB SCSI on the internal ribbon that has OS X 10.2.6, and a generic USB 1.0 card. I lose sound whenever I use the ATA drive. My work around is to "eject" the ATA drive at login if I want to use itunes, or anything that needs sound. The sound is excellant when using the SCSI only. I wish I had a graphics card to enable QE and see what happens. I am open to any suggestions. Regards, Mike M. |

Thanks to doug.duchene for suggesting it: enabling QE does help make the sound work better for me. (9500 / 1 GB+ / 800 MHz Sonnet G4 / Radeon 7000). Quicktime movies still kills it, but games and system sounds don't break as easily. |

TNT was also the 7500 motherboard. My 8500(604/190) runs OSX Server 10.1.5 but it has sound for sure(Also 820 0752A Motherboard). I also have a 820-0564-09TNT Val-4 PM7500 running 10.1.5 on a 180Mhz 604. I THINK it has sound all right also. But I can't test right now. I think 10.1.5 is different for sound issues anyhow. Marty |

I have 3 8500's and 4 motherboards. One of my 8500's now runs fine in both OS 9 and OS-X, no sound problems, with either a VST or Ahard ATA/66 board and an IBM IDE drive. This 8500 has a motherboard with the part number 820-0752-A. The sound stutters when I add an IDE drive in another 8500 that has a motherboard part number 820-0564-09 TNT VAL-4. Can we do a survey of old world macs with IDE drives and see if there is a correlation between motherboard part number and stuttering? |

Doug, Thanks for the information. I have followed the numerous postings that discussed the "loss of system sound" issue when using ATA hard drives. To date, I have been unable to figure out any solution. Your experience with QE comes the closest to a "cause" and "favorable effect" so far. You are probable correct to suspect a "bug" that QE gets around when enabled. I will look for a PCI QE capable graphics card since upstate NY is some distance from WA. Thanks for the help. |

Mike, Perhaps there is a bug in the OS that is only hit when Quartz Extreme is not enabled. I started PCI Extreme by running the installer and rebooting my system. I verified that it did enable Quartz Extreme by running the test application referenced in the PCI Extreme readme file. I'd suggest finding someone to borrow a supported video card from before purchasing one since its not clear what the problem is, just what fixed the problem on my machine. If you live reasonably close to the Seattle, WA area let me know. - Doug |

to doug.duchene: Can you think of a reason why using PCI Extreme helped your sound? Would it be worth upgrading a 8500 currently using onboard video to get sound to work, and achieve some faster video at the same time? |

I recently had sound working flawlessly on my 7500 with a Sonnet Tempo Trio, but managed to break it recently while upgrading to 10.2.6 along with the new Sonnet Temp Trio firmware, and attempting to use the Sonnet USB 2.0 drivers version 3.0 (because the 2.0 drivers don't support hubs). Last night I managed to get sound working again. I was able to play several songs that had been ripped from a CD using iTunes while repairing permissions on my boot drive (where the audio files live) and loading web pages into both IE and Safari (i.e. lots of IDE hard disk activity along with USB mouse and keyboard activity). The steps I took to fix my problems are: 1) Downgraded my Tempo Trio firmware to version 3.2.5 from 4.0 (This made no difference to the audio problems). 2) Installed the 3.1.2 USB 2.0 drivers from the Orange Micro web site (this improved things somewhat (and does allow my hub to work along with allowing the system to boot with the PocketMac USB driver installed). 3) Reinstalled PCI Extreme (This resolved my sound problems). Hope this helps, - Doug |

davelentz --- Which slot do you have your firewire / usb card in? I've tried the imic w/ the orange micro card, and it woks...... but when I do something that would normally cut the sound from my built in hardware, my imic sound not only drops but so does my entire usb chain. |

I was a bit premature when I said fixing it so that both Classic and OS X were using USB audio -- I'm having a spot of trouble getting Classic to utilize USB audio -- doesn't seem to recognize that it's even there, regardless of what extensions are loaded in the Classic environment (in the Real World, it works fine under OS 9.1) This smells disturbingly like a "feature" of the TruBlueEnv VM, that maybe it intercepts all Classic audio and maps it to whatever OS X is set to -- maybe it has to do with my use of 9.1 instead of pushing the OS 9 envelope to 9.2 and whatever "helpers" OS X places into the Classic environment the first time it is run. I dunno. The problem continues -- but I'm fairly confident that it has to do with Classic looking for non-USB audio and OS X using USB. |

1) abandon the builtin sound jacks, at least for output. I'm running all my output sound through a Griffin iMic, off a USB hub connected to a Radoc Firewire+USB 2 combo card. 2) IF you do as I have and are using USB audio, make ABSOLUTELY SURE that your Classic config is setup the same way as OS X. I just solved a mysterious loss of audio out when multiple apps were running -- sure enough, one of them happened to be a Classic app trying to drive sound through the builtin hardware while OS X (10.2.6) was merrily trying to run everything through USB audio. I could logout and log back in, and the sound was back, but at some point when I had several apps concurrently running (and after all, if it wasn't for that, we'd probably all be running System 6.0.8, right?), the 7500 would be struck soundless. Getting Classic and OS X in sync with how they're doing sound looks to have solved the problem. |

for me sound in through the microphone port works but the RCA jacks do not under OS-X. I am also able to do video via USB in using Interview hardware and the Interview Capture software. I have 3 8500's (I keep buying parts machines and fixing them). Two were origionally 120 MHz and one was 132 MHz. Under OS-9 two of them have audio stutters with either the VST or Acard IDE cards and the other (one of the former 120 MHz 8500S) is OK. I have not tried OS-X on the 8500 that does not stutter in OS-9 since that is my main 'puter and I should not risk messing it up. Next time I have the covers off I will check the version of the motherboards to see if there is a trend. George |

IDE seems to be the problem those that are all SCSI don't seem to have this situation. I am running an 8500 G3/500, 384 RAM, several SCSI hard drives from 9 to 47 Gig, CD, CDR and SCSI scanner (only works in 9 since I won't pay for the software to run it in X yet) along with USB 1, USB 2 and Firewire cards running 10.2.6 with no problems. Like almost everyone else with Old World machines I have to use external speakers to regulate the master volume, some programs like iTunes allow some volume control from inside the program. Oh like others I don't believe sound in works but it has never worked on this machine port was broken before I got it. Jim |

New to the forum but have been messing with OSX in an 8500 since the days of OSX beta. Should have joined long ago. Current system setup PowerMac 8500 OWC G4/450 running at 400 in an XLR8 carrier 512 Mb RAM VST IDE card (flashed for OSX) Segate 9 Gb SCSI drive (startup drive) IBM 80 Gb IDE drive TDK 401218 IDE CD burner MacOS 10.2.6 Powerlogix USB/firewire card Everything works great except for audio. Audio works great except whenever the computer hits the IDE drive the sound breaks up or quits. If the sound quits the only solution I have found is to restart the computer. This happens if I swap processors (G3/400), IDE cards (acard IDE/66), or hard drives (IBM 60 Gb or Western Digital 4 Gb) with my other 8500 that runs OS 9.1. The problem is worse with the acard IDE card. I'm slowly going back through the forum but this seems to be a common problem. I do not remember having the problem in the MacOS 10.1.5 days, the audio would occasionally stutter but would not quit. Has anyone found a solution to this yet? TIA George |

carstena, you have a Macally firewire/USB card and sound out works fine. Right? Is anyone else having this sound out problem use a Macally card, or is the problem isolated to the Sonnet USB/Firewire products? Rusty |

Dito, No sound on my PM9600 XLR8G4/450, PowerDomain 29160N SCSI with a 36.7 GB IBM7362X Formatted with HD Speedtools 3 partitions 4GB OS9.1, 4GB 9,2,2, 27+GB OX10.2.4., ATI 7000 video card and 1.5GB (12x128 non/edo memory). NOTE! Since I removed XLR8's MACh control 2.6.1 OSX which broke under Jag (Updates in the works) and installed L2CacheConfig , Jaguar has been stable for two days but has been operating using "safe boot" I think I just answered my own question. Does "Safe Boot" effect sound? |

Hi, I've got : 7500 with G3/400 and two IBM SCSI drives with adapters to the internal fast bus including also a scsi cd-rom drive. Macally firewire/usb card. OSX 10.1.5 installed with sonnets PCIX installer as I XPostFacto had problems recogninzing my cd-rom device. - Sound "OUT" works perfect with alle applications: Itunes, SparkME, Windows Media Player, Realaudio etc. - but sound "IN" dosen't work. It dosen't appear as an option at all in system settings. None of you folks here have been mentioning this issue - am I alone here? A couple states that "everything" works - but does that include sound in? |

I called Sonnet tech support. The tech said he's heard of the problem with sound on 7500's. I told him the problem, at least for me, centered around my Tango card - card installed, sound goes away - card unplugged, sound seems fine. He told me to update my cards firmware. I ran the updater-it said no update needed. If I boot in OS 9, the sound seems fine, even playing MP3's off my connected firewire drive, although i did not test for very long. |
