Sound effects missing in Lion

That's very strange. So you can't get any of the SFX to work or just trash? I've found that with Mountain Lion some of the other SFX stop working when the trash sound stops now. Unplugging the speakers and plugging them back in gets everything working again for me though. It's happened about four times in the last month now. Just weird.

Oh, FWIW if you were thinking about it, I'd stay away from upgrading to Mountain Lion for now. It may or may not affect your MBP, but a number of folks have experienced a serious battery drain/health problem after upgrading. It's had a very bad impact on my late 2010 MacBook Air. It certainly doesn't happen to all, but enough that I'd wait until it's been sorted out. More here.

Sorry, I meant to say Mountain Lion in my original post and I just realized this is posted in the Lion discussions. D'oh. Apparently also an issue in Lion as well as Mountain Lion. And yes - all sound effects, not just trash. They all went silent. It's very odd. I'm just glad the headphones "cure" worked.

Ahhh...got it. Still wondering what causes this. It's not critical, but it is annoying. Perhaps someone will figure it out one day.

Enjoy your new MBP!

I just stumbled again over a funny thing that I want to share:

When I plug in the earphones, I can hear all those sounds come through one after the other. This seems to me as if the sounds had been suppressed and sat there waiting to come out the very moment I plug in the earphones.

Btw, I have recently done a clean install of Mountain Lion on my iMac (early 2008) - and this phenomenon still persists. Seems to be a hardware issue rather than software.

Yes, as mentioned earlier, I and others here have experienced the same thing. We have the same machine and I've run it w/o the speakers attached and it never happens. But it continues to do so even through Mountain Lion 10.8.2 when I have speakers or headphones connected. It's pretty sporadic but in my case it seems to happen after I've visited some websites and running audio and/or video files (using Safari). No idea why though. So agreed...it must be some sort of hardware issue. Just weird.

Hi there... I have the same issus until I reboot. I have not tried plugging and unplugging headphones to see if that makes it work again.

There gotta be a workaround or something ....

Thanks

Sorry.... My issue is on the MacBook Pro w/retina

Hi Rich. AFAIK this odd behavior is still a mystery. FWIW my iMac (OS X 10.8.2) hasn't had the issue for several months now. Unplugging the external speakers for a moment, letting the "pent up" sound effects play (on top of each other) through the built-in speakers and plugging the external speakers back in always resolved it in the past though. Weird.
