Yesterday I could play music and actually hear something, but as of today, my MacBook Pro speakers aren't producing any sound at all.
Here is what I tried:
- rebooting (a cold reboot too) several times
- internal/external speakers
- PRAM reset
- Reinstall iTunes
- Using headphones
There is no red light in the headphone jack.
The only thing I did was updating my iTunes to the new 10.5.3 version. But I doubt this is the cause because other programs aren't reproducing any sound too. So, no sound at all on my MacBook Pro (mid 2011). Any idea or hits to get the sound back?
And to make it even more weird, the mail-app is making sound when sending and receiving mails. But iTunes, QuickTime, VLC, Safari,... These apps aren't making any sound at all!
