No sound in os 9.2.2

Question

Hallo everybody,
I have exactly the same problem as "elzef" from France, post: Nov 19, 2005, 12:53PM. I have also tried everything I know to find a solution like zapping the pram, nvram, clean installation on another partition, but in vain. I searched the web extensively and what I gathered is that I must have the exact os 9.2.2 edition that came with the computers like mine(is it right?), because I bought the computer secondhand and this was missing. So I tried to find and buy the disc(s) (ebay and mac software stores), also in vain.
My boot rom is: 4.4.8f2 and maybe it has lost its validation(trying various os 9 editions) but if so how does the computer work ok with os x 10.3.9?
I would be grateful for any help.
My email is: [email protected]
Thank you,
Yannis.

Answer 1

1)Sound is ok when I boot to os x and working either
in os x or in its classic mode.
3)In both above cases I do hear the normal startup
bong.
Ok, that eliminates a problem with the speakers, wiring, or other hardware.
2)When I boot direct to os 9.2.2 I have no sound
regardless of application (neither system platinum
sounds you set from Appearance Control panel)
And since sound works fine in X, but not 9, that narrows it to a device driver or control panel setting.
4)When I open the Sound Control panel in case (2) and
press "input" it displays the message: "The settings
for the sound input source cannot be adjusted because
the device is in use by another application", but I
have checked both foreground and background for
running applications and nothing is on.
4)When I try Quicktime 6.0.3 the message is that I
can't hear the audio of the file because there is no
audio device. Tried other Quicktime versions, the
same.
See what I said about the 3rd party sound card below
9.2.2 installation because on my two installations (one >localized and one international-different hd partitions, os >x another)
As long as they are on different partitions, this should not be a problem.
I used restore and install grey disks and
used also the downloadable upgrades from Apple's site
you mention.
Not a problem there - that's how it should be done
and muting is off. I will check for the spring
contact but I think that something like this would
also affect the sound in os x or no?
No, if sound works in X, then this is not the source of the problem
borrowed a sound card, installed it for a check and
it is recognized ok in os 9.2.2 and os x, so it seems
that os 9.2.2 does not see the machine's own sound
device only.
borrowed a sound card....if the card is still installed, or needed some sort of driver installed, then it's driver could be what is interfering. Remove te card if you haven't already done so, then boot to 9 while holding down the shift key This will turn off all extensions.
If you have sound then, then your problem is an extension conflict, which is easily resolved (but a tedious process)
Alternately, instead of hoilding down shift, hold the spacebar until extensions manager appears, and select Mac OS 9 only. This will turn off all non-apple extensions and device drivers. Close the extension manager. Booting will continue.
Test for sound
Thank you for your effort,
You're quite welcome
