Recently installed an update and discovered that Flash no longer played sound in my browsers on the Intel based MacBook Pro from Apple.
No idea why. Sound works elsewhere, including the browser for non-Flash (e.g., Quicktime) content.
Found the fix online: Open GarageBand, play a note or two on the keyboard, and quit. Whatever cleanup GarageBand does, fixes the sound problem — you don’t even have to close the browser.
Worked for me!
Thanks so much for the info! Works on the Macbook as well.
Thanks! Worked perfectly.
Also works for PowerBook!
Worked on an iMac G5 too. Excellent tip.
