I found my alert sounds to be annoying so I turned them off using an extension called systemsquelch(?). &nbsp;I am unable to use real audio due to an error 50. &nbsp;I've gone back to my original system 7.5.5 and double checked my sound control panel following the suggestions in the appleguide. &nbsp;Still no sounds. &nbsp;when I try to adjust the volume button the menu bar flashes. &nbsp;My audio cd plays. &nbsp;Please advise.

Mac PowerPC Performa 5260.

I found my alert sounds to be annoying so I turned them off using an extension called systemsquelch(?).  I am unable to use real audio due to an error 50.  I've gone back to my original system 7.5.5 and double checked my sound control panel following the suggestions in the appleguide.  Still no sounds.  when I try to adjust the volume button the menu bar flashes.  My audio cd plays.  Please advise.

No Alert Sounds

Apple's early computers ran on a variety of operating systems, including a Pascal version and one based on CP/M, before releasing its ProDOS with the advent of its 16-bit computer. With the release of the Lisa, which had its own OS, Apple and computing entered the graphical age; it was followed by the Macintosh, which offered a series of "System" operating systems. Other Mac operating systems included PowerPC until Apple acquired NeXT and folded it into the Mac OS. Current operating systems for Apple devices are Mac OS-X and iOS.
