PowerBook G4 Dual-Layer SuperDrive: Audio looping/echo problem (#2)
PowerBook G4 Dual-Layer SuperDrive: Audio looping/echo problem (#2)
We previously reported on an audio looping/echo problem that is affecting every PowerBook G4 (Double-Layer SD), 15" and 17". The problem causes audio to intermittently stutter, echo, or skip backwards.
As noted in prior coverage, Apple posted a Knowledge Base article addressing the issue, offering the kludgy and often ineffective workaround of running only one audio application at a time.
Previously reported workarounds involve turning off AirPort and deleting the iTunes Helper Login Item.
Readers now offer some additional attempts at solutions.
Turning input volume off MacFixIt reader Vic writes:
"I had good results zeroing the volume of the selected input device (internal microphone) in Sound / Prefpanes."
Stopping then restarting media Another reader writes:
"I have a 3-month old PowerBook Dual-Layer SuperDrive and have experienced this in iMovie during playback. If I stop the movie I am working on and then start again, the problem goes away. It doesn't happen at the same place in the movie when replaying the movie."
