Help! SUBWOOFER is QUIET after Resetting PRAM

Hi, I have 2 desktop speakers with a big subwoofer. Well after I reset my PRAM I noticed my desktop speakers work but the subwoofer is very quite and it doesn't have the deep bass it did before. Does tresetting the PRAM do something to the audio settings. I believe I read that somewhere and how can I fix it?
Thanks
According to this articel the PRAM does affect the speaker volume. I went into "Preferences" and my desktop speakers work, but the Subwoofer is not working properly. It was eorking fine before I reset the PRAM. Is there a setting or a file I need to replace etc?

Noticed another problem. After I reset my PRAM my subwoofer no longer works as it did before I reset my PRAM and when I power up my Mac Pro Tower it stars and then when it's starting it chimes and does another "restart".
Before I reset my PRAM it would just start up once and not restart. What's going On? And what is NVAM? Do I need to reset that too?
Please help.

External Display resolution problem after resetting PRAM

Gello, I've got Fujitsu-Siemens P19-2 monitor hooked up to my MbookPro and after resetting PRAM the correct display resolution disappeared from the "Displays" menu in System PReferences.
So did the refresh rate option...
What do I do?
I really need to change the refresh rate and the resolution, but the refresh rate button is grey and unclickable, and the resolution simply isn't there (I need 1280x1024).
REsetting PRAM and SMC didn't help.

After a couple of resets everything went back to normal

Can't boot after resetting PRAM??

Before attempting to install Leopard, I upgraded my non-leopard compatible 1.2 GHz processor to a 1.8 GHz leopard compatible one. I also doubled my RAM from 512 to 1024 MB. I then installed leopard but upon restart it continually shut down. Holding down the "c" button at startup, I was able to boot from the leopard disc. I could then even start the computer from my old Panther startup volume. I used 'Disk Utility', ran 'disk repair' and reinstalled Leopard. The same problem persisted.
In another forum someone suggested resetting the PRAM as a next step. This I did but now I'm really freaking out because my computer is totally nonresponsive. My computer starts, I no longer hear that wonderful symphonic major chord, the Apple logo appears (with no circular loading bar), and there it remains frozen. I can no longer boot from the Leopard disc or any other disc (TechTool Pro, DiskWarrior). What should I try now?

There are several things you can do.
If you can’t start up after resetting PRAM
If you have a redundant array of independent disks (RAID) scheme set up, your computer may not start up if you reset parameter random-access memory (PRAM) when you restart.
If this happens, hold down the Option key while you restart your computer, and select your startup disk when you see the prompt.
f a message says “type ‘mac-boot’ and press return”
If the message “type ‘mac-boot’ and press return” appears when you try to start up your computer, some of your computer’s internal settings need to be reset.
NOTE: It may be helpful to print these instructions before you begin.
Or, try these suggestions:
■ Shut down your computer. Turn the computer back on and immediately hold down Command-Option-P-R, continuing to press until you hear the startup sound for the second time. This resets the computer’s parameter random-access memory (PRAM).
IMPORTANT: Resetting PRAM may change some system settings and preferences. Use System Preferences to restore your settings.
And finally
Restart with the X key
Hold down the X key and choose Apple menu > Restart. This may force the computer to start up using your Mac OS X system.
If the computer starts up, release the X key. Choose Apple menu> System Preferences, and then click Startup Disk. Make sure that the disk containing Mac OS X is selected.
Restart with the Option key
If you are unable to start up using the X key, choose Apple menu > Restart and immediately hold down the Option key.
When icons start to appear in the center of the screen, release the Option key. Select the disk that contains Mac OS X, and then click the forward arrow to continue starting up.
■ If resetting PRAM doesn’t solve the problem, reset non-volatile random access memory (NVRAM). When the “To continue booting ...” message appears, type “reset-nvram” and press Return. Then type “reset-all” and press Return.

Sound still bad after resetting PRAM

Yesterday the sound on my laptop speakers began sounding really bad (almost like it's crackling?) and after resetting the PRAM and resetting the audio through a command on Terminal, it still sounded bad. It made me think it was a problem with the speakers themselves but now that I'm using my headphones it's still pretty bad. What do I do? Is there a way to fix this without having to take it in for repairs?

That's good : these articles explain in more detail.

Temps rising again after resetting PRAM; SMC Version: 1.4f10

After running the firmware update, I was happy to see my MB running very coolly this morning (35 C.). After resetting my PRAM per AC's instructions for a display issue, I noticed my machine running in the high 50s/low 60s once again--same as before the firmware update.
Is this still in the normal range, or is there something else going on here?
Thanks in advance.

Thanks Eric. Actually, I'm not plugged into a display just yet. Just seemed strange the temps went up 20-30 degree C. Perhaps it was the time of day and duration of operation that accounts for the change.

Bluetooth not available even after resetting pram and smc!

Hi, my bluetooth on mbpro is not working now, i've tried resetting pram and smc but it is still the same ! could it be a hardware problem?

Try doing a Safe Boot and then reboot normally...

If you are still having Fan Issues... you could try another SMC...
Just a thought...

After a PRAM reset my MBP 1,1 display is split into 4 parts each displaying the same image. What is causing this and how can I fix it?

After resetting the PRAM/NVRAM (control, option, P, R) on my Macbook Pro 1,1 (2007) running 10.6.8 The screen is now split into 4 parts, each displaying the same thing. The screen immediately appears this way at the first grey screen, however if I do another NVRAM reset, upon restart after the second startup chime, the screen is normal but once it gets to a certain point around thetime the cog stops spinning, the screen flickers, turns blue and splits into four again.
Another thing is when I tried using the Apple Hardware Test I couldn't read the instructions as the resolution was too small, but once I restarted and change my display resolution in System Preferences, the resolution was readable in AHT. I assumed the System Settings were loading when the OS had booted and that AHT runs without any of these settings (if that makes sense?)
I've not used any third party utilites and everything working fine except for some battery issues which are gone now (the reason I tried the PRAM reset)
Any help would be much appreciated

HT1379 Holding down cmd-option-p-r opens utilities instead of resetting pram on iMac. Can anyone help?

Hi!
As seen on another discussion I am not the only one that experiences slower inter tenet after upgraded to Lion. https://discussions.apple.com/thread/3228040?start=0&tstart=0
Some suggested that resetting PRAM is the solution, so following the apple support instructions http://support.apple.com/kb/ht1379 I tried to hold cmd-option-P-R keys while starting my iMac. This should just reset the PRAM and restart the computer. Instead, it opens Mac OSX Utilities, so I have to say that promblem(s) not solved....
Could anyone help?
Thanks!

As X423424X said you need to hold them down during/after the boot chime/startup sound. Chances are you've got a wireless keyboard, the Bluetooth module on the iMac activates only after/during the chime.

Mac do not startup after reset of pram

My mac won't startup after I reset the pram. I had to reset my pram because I was trying to fix my probem. I cannot connect to the wifi because it said no airport card installed. Help!

Do an SMC reset, then report back if that doesn't get it going:
Shut down the computer.
Unplug the computer's power cord.
Wait fifteen seconds.
Attach the computer's power cord.
Wait five seconds, then press the power button to turn on the computer.

After being connected to a charging source overnight try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

TS2094 After resetting the pram, the screen only shows a folder with a question mark inside. What does this mean?

I followed the initial steps in this post and reset pram. After restarting, the screen just shows a folder with a question mark. What does this mean?

Thanks Niel, I tried using Option and nothing happened so I next tried inserting the Leopard disc and rebooting while holding C. Nothing happened until the disc was ejected and then the folder with question mark reappeared. I inserted the disc again and at this point and it booted OSX. I tried to acess disc utility to repair but my harddrive wasn't listed, only the CD drive and the OS disc. Does this mean I'm lost everything?

Reset PRAM after Yosemite?

When is it advised/necessary to reset PRAM? This was suggested as a cure to massive iMac (2010) blinking/flickering that occurred after Yosemite installation, but I am afraid to perform a drastic move without getting green light from the experts. BTW, are there other ways to cure this absolutely annoying pixel flickering? Any chance that Apple will take care of it soon? Is it a Yosemite bug, or just a message from my not-that-old iMac begging for replacement?

I am afraid to perform a drastic move
Very simple and not considered drastic, try it and see if there is an improvement.
Try resetting NVRAM/PRAM http://support.apple.com/kb/ht1379
Information stored in NVRAM / PRAM includes:
    ▪    Speaker volume
    ▪    Screen resolution
    ▪    Startup disk selection
    ▪    Recent kernel panic information, if any
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.
Your computer's PRAM and the NVRAM are reset to the default values. The clock settings may be reset to a default date on some models.
<If your computer is Open Firmware-based (Power PC) >
Resetting NVRAM via Open Firmware A number of users report that resetting NVRAM resolves wake-from-sleep issues.
In order to perform this process, hold down the Command, Option, O and F keys at startup. When the prompt appears, type:
* reset-nvram (then press return)
* reset-all (then press return)
Contents of PRAM on earlier Macs
Some earlier Macs store these settings in PRAM:
    ▪    Status of AppleTalk
    ▪    Serial Port Configuration and Port definition
    ▪    Alarm clock setting
    ▪    Application font
    ▪    Serial printer location
    ▪    Autokey rate
    ▪    Autokey delay
    ▪    Speaker volume
    ▪    Attention (beep) sound
    ▪    Double-click time
    ▪    Caret blink time (insertion point rate)
    ▪    Mouse scaling (mouse speed)
    ▪    Startup disk
    ▪    Menu blink count
    ▪    Monitor depth
    ▪    32-bit addressing
    ▪    Virtual memory
    ▪    RAM disk
    ▪    Disk cache
