Apple Event: May 7th at 7 am PT
Hi all,
I try to run my jacks ports to my mac pro (early 2010), but since the last Lion update, I haven't any sounds from the sound ports (only the sound of my Cinedisplay works). Same things on my Bootcamp partition, no headphone sound on Windows 7.
Must I reinstall all my system ? (both OSX & Seven ?)
Note : I haven't the mac BUUUZ at the computer start 😟
Could you please help me ?
Mac Pro (Early 2009), Mac OS X (10.7.5), Quadro 4000
The physical jacks are complex little things with mechanical parts inside. Sometimes they get stuck. The best way to get them un-stuck is to insert and remove the plug while wiggling it around a dozen times.
Nop, I just try a dozen times but no change
Reset the SMC > Resetting the System Management Controller (SMC)
1. Shut down the computer.
2. Unplug the computer's power cord.
3. Wait fifteen seconds.
4. Attach the computer's power cord.
5. Wait five seconds, then press the power button to turn on the computer.
Then the PRAM > About NVRAM and PRAM
1. Shut down the computer.
2. Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
3. Turn on the computer.
4. Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
5. Hold the keys down until the computer restarts and you hear the startup sound for the second time.
6. Release the keys.
Works with me on OSX, I try under Windows seven now
Ok, the SMC + PRAM resets were backs the headphone on Windows 7 too ! 😁
WHOUHOU ! 😍
No jacks ! (headphones, MP early 2009, 10.7.5)
