Sound Output Problems

hey folks,
I'm here sitting on my Macbook Pro using Skype talking to my parents on the other side of the world, and out of nowhere, using a headset connected to a USB iMic and line static type noise started on my headphone. The input works fine, recordings and live audio chats work fine for input.
Now when I unplug the iMic and use the Macbook Pro internal in/out. Again the input works fine, but I normally have my laptop on mute, and when I unmute the sound or just press the F4 key once to raise the volume, up comes a load POP! and there is no volume whatsoever. It's silent until I mute it again when comes another load POP!.
Funny when using the iMic it sounds like a ground loop or some other noise. But I can still get audio. But when using internal is just pops and I get nothing.
Any hints or ways I might figure this out? I'm going to try booting into a live cd or something to see if the same problem exists.

Thanks iVmichael,
That probably would have worked. But before doing that I booted into Ubuntu 8.10 live cd (which worked really well BTW, video, sound, wifi, bluetooth, etc.)
And after rebooting back into Mac OS X the sound works fine.
So the pram reset might have worked as well.
Thanks!

Sound outputting problem

Hi All,
I am having continuous problem solving the following sound issue:
When burnt both video and audio files, having used Compressor and Toast Titanium 9, the video plays fine however my sound plays only in two channels.
The sound was designed and edited in Soundtrack pro application. The output setting selected in Compressor is: 5.1 Surround Quicktime, 96.000 kHz.
There is also this warning box coming up, when changing the sequence setting audio output to surround, saying:
' The current audio device does not support the number of outputs set in the sequence settings audio outputs tab.'
Any help/advice will highly be appreciated.
Stephen

Hi Stephen,
First, I'm assuming you are using the optical out of your mac to go to the BDV. With it plugged into your mac goto your system prefs and in the Sound>Output>Devices select Line Out Digital.
In FCP goto Audio Video Settings>A/V Devices>Playback Output>Audio and select 'Built-in Output'. Now click the options button next to the selector. Set number of Channels to 6 and sample rate to 96000.
Now goto your sequence settings (Cmd-0) and under the Audio Outputs Tab click the selector that says 'Load Audio Output Preset' and select 5.1 and click OK
Back on the timeline right/ctrl-click the lock symbol on each track from 3-6 and select the following:
3: 3 (Ctr)
4: 4 (Sub)
5: 5&6 (rear L)
6: 5&6 (rear R)
1 and 2 will already be setup for Front L&R
That's it for FCP 5.1 support
In Toast you must set the audio output to Dolby Digital. PCM only supports Stereo on Bluray and DVDs. Just customize the settings in Toast. Click the customize button, then under encoding select Custom and choose Dobly Digital under Audio.
That should be you good to go
All the best

HP ENVY 17 microphone and sound output problems

Hey i have a HP ENVY 17, and i have been having some problems with the microphone, sound outputs and the sound in general. The microphone output haven't been working ever since i got the notebook in November. at first i thought it was problems with the settings, either on the computer or on Skype, which i used for communication. I tried with other Voice Chat programs such as Mumble, Ventrilo and TeamSpeak - neither worked. I got a friend over who knows a little bit about computers, and the only thing he could think of was that the microphone output was non working. I am using Steelseries 7H headset. Now i have to use the integrated microphone which often gives background or typing noise.
Lately i am only hearing sound on the right ear, i have checked my headphones with an iPod, so i know there is nothing wrong with them.
The third problem occurs when i turn the volume over 20% on the computer. It starts to make a background noise, almost like a waterfall, both with headset and without.
Another little problem i have is nothing to do with sound, but since I'm posting this already, i thought i could atleast ask. When i play games the top left side of the computer, right over the fan can get hot while the fan is working on hardmode. If i play really graphic-focused games, like Crysis 2, it gets super hot(i burn my hand if i hold it over the fan). Is this just because it's a laptop and the games demands too much? Or is it dust in the fan or something? And what can i do about it? That last question counts for all the problems
Thank you on beforehand
- Kirrod

I still need help, if there are anyone here who thinks they have any kind of solution to my problem. Like; how do i get it repaired? Send it to HP? How long will it take?
Im sorry if my english is not so good, it's my second language. It might be called microphone input, and not output. The place you put in the microphone cable.
Please help!

Mac Mini Singel Core Sound Output problem

Mac Mini is connected to a amplifier, the sound-output is put on 100% this works perfect, but after shutdown the soound-output is set to 50% is it possible to set this always on 100 % ?
thanks

Is the mini connected via the standard analog 1/8" audio jack or via a digital cable?
You could try resetting PRAM from this Apple doco:
Resetting PRAM and NVRAM
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.

HDMI sound output problem with gtx670

Hello again!
I have recently purchased a brand new Samsung TA550 LED monitor to use with my Mac Pro desktop. My Pro posesses a GTX 670 graphics card with (obviously) an HDMI output channel. The thing is, when i plug the hdmi cable on the card and on the monitor and configure the monitor for the appropriate video settings, there is no audio. Then I go to the system preferences ----- sound------ output, and there are no options for hdmi or my tv/monitor.
Does anyone know whats goin on?
Thanks

It is flashed? or it is a straight PC card. And while there is support (you probably want to check other threads and sites and wait a day to upgrade to 10.8.3) some PC cards will not act and behave the same as say under Windows.
I would contact MacVidCards (ebay and MacRumors forum) and see if he can flash it or knows more.

Has anyone else had optical sound output problems since the last Apple software update?

I have just read an article about this problem and it seems that there is an issue with the last software update from Apple which has caused problems with the optical sound driver.
My optical output stopped working a couple of weeks back which would probably coincide with the last update that was installed. Still have a red light at the end of the cable but no sound is transmitted.

here's a thread with a possible solution.
https://community.verizonwireless.com/thread/790883
if clearing the system cache doesn't work, a factory reset should (just back up anything you don't want to lose).

MagicJack and Sound Output Problems

I have an interesting issue occurring on my Mac Mini. I am running 10.6.2 with all available updates and have a magicjack connected. I am also using a toslink adapter to my bose system for digital audio out.
Here's my problem:
When I go to System Preferences and select Audio there are 2 choices for output; Digital Output and USB Internet Phone by Tigerjet (magicjack). I, of course, have it set to Digital Output and things work great until Time Machine connects to my external HDD I have connected to my AEBS. When it makes the disk available and starts to backup, my selection of Digital Output changes to USB Tigerjet and my audio stops working. No matter what I do I can't change it back without unmounting the magicjack and quitting all apps that are using sound. I have to physically unplug the magicjack first, then I can go back and change it to Digital Output and my sounds works but the next time I plug the magicjack back in and time machine wants to run it all happens over again.
Anyone have any ideas? I use the magicjack as my home phone so I can't just leave it unplugged.
Thanks

Tried that, thought it worked, but when I played a movie it changed back to USB TigerJet. Thanks for the permissions tip though. I apparently had 100's of files with wrong permissions.

Sound output device problem since 10.6.2 upgrade...

wHey, I've had a look through some other forums and have found solutions and so on to this problem, which is basically this:
Since the 10.6.2 Upgrade my sound output device changed from 'Headphones' to 'Soundflower (2ch)'...The three options are as follows on Sound preferences through System Prefs...
Headphones
Sondflower (2ch)
Soundflower (16ch)
I use external speakers, so headphones is important to me, but everytime I change it back to headphones, the next time I restart the computer it switches back to Soundflower (2ch) ... It's only on my user account as all other accounts are fine, I've reinstalled OS X already, and have even since this problem started, bought a new iMac (no, not just cause of the problem lol)... Done a timemachine restore, yet the same is happening on the new iMac, and it's driving me nuts... I've called Apple Support they suggested reinstalling OS X, I've done just that, but it's still doing it... There must be something I have installed...Any help?
I'm hoping someone has some sort of Terminal code to switch it to set to 'Headphones' as DEFAULT Output, as there is no such way to do it on Sound preferences.
Any help greatly appreciated, thanks

Refer to Apple - Support - Discussions - System does not store my sound preferences or Apple - Support - Discussions - Sound preferences sometimes messed up after boot for removing Soundflower from your Mac.
However, AFAIK, there is no way to make 'Headphones' the default sound output device, since the switch among built-in audio, headphones, (& optical output on Macs with a dual purpose optical/analog output jack) is controlled by what you do or don't insert into that jack.

USB (Mega stick), sound output and PS2 problems

==USB problem==
The MSI MEGA STICK do not work with the MSI K7N2 Delta ILSR.
When you plug it, its recognized, you can write on the MEGA STICK, delete files but cannot READ from MEGA STICK. It freezes while display "reading". I have tried on lots of PCs. Only my MSI motherboard do not work properly. The same problem with my 2 MEGA STICK. And i had tried Windows XP and Linux. Same problem. Others USB devices works fine. Even card readers...
==PS2==
My optical wireless mouse do not works properly. When i turns on the computer, it works ok. If i restart, do not work. Restart again, works. And go on... Only this mouse. Others MB works fine.
==Sound Output==
And also with my sound output. The eletrical one (coaxial).
It do not work with my 5.1 home system. It works fine with my old SB Live. It gets worse when i use my tv output from my Radeon 9100. It only works SOMETIMES when the tv output is not plugged in.
Thanks to all that could help me.

Mega stick.
have you updated the firmware ?
No. It Freezes before being able to update. Also the update do not tell about solving this problem
"Firmware version: 2.05
Update items
1. Improve delete MP3 and voice files function.
2. Fix device will restart while forward/backward Voice file."
you do know that windows xp does not come with usb2 drivers.
sp1 does and you have to install them yourself.
go to device manager and delete all usb entries and reboot and windows will install the usb2 drivers next time you boot.
if you get a slipstreamed version of xp you dont need to do this as it installed usb2 drivers rightaway.
slipstream means a xp disc with sp1 on it.
My XP cd is already SP1. Also tried on BIOS to use only USB 1.1V
PS2.
tried to use the other ps2 contact ?
No. Could i use the keyboard PS2 to plug the mouse?
SOUND.
this is not my area but it could be a good idea to post what the equipment is.
have you tried the latest drivers from http://www.nvidia.com ?[/quote]
Its a brazilian brend. You wont know. CCE. Its works fine with DVDs, my old SB Live! and others. Only with my K7N2 do not work properly. Its an AC3 decoder. The problem gets worse when i use the Radeon 9100 tv out.
Look like the problem on this thread.
https://forum-en.msi.com/index.php?threadid=29572&sid=&hilightuser=26427
This is my old thread. Never solved. :-(
https://forum-en.msi.com/index.php?sid=&postid=319195#post319195
When i updated the BIOS, it got even worse. Not even with the tv output unplugged it never worked anymore...
Its very disapointed to buy an expensive MB and realized that it do not work properly...
Thanks yo your help.

Problem with mac's sound output

Recently, I have upgrade my mac to Yosemite. And then the problem comes along. I found that my mac always didn't output any sounds. After some searching, I found that in the sound panel of system preference, the sound output device always automatically changes to "Soundflower(64ch)". If I change it to "Internal Speaker", then the sound comes out. How the output device "Soundflower(2ch)" and "Soundflower(64ch)" come from? And why the sound output device automatically changes to "Soundflower(64ch)" every time when I plug in an earphone or restart my mac?

Try this, go to Users/Library/Preferences folder. navigate down to com.apple.systemsound.plist. Remove it from the folder to the desktop.
Now go to System Preferences/ Sound and input the preferences you want for your sound output and input etc. This creates a new .plist in your Users Library
Preference folder. Now either logout and then login or restart the computer. These new settings should now hold. If they do and you are happy then you can trash the older .plist file.
Good luck.

Having problems choosing sound output through HDMI to my television, any one any ideas?

Though listed in the sounds options, I can't seem to choose a sound output to my TV through HDMI. I have sound output to headphones via the headphone socket or usb, but when I highlight to the HDMI TV option it justs returns to the top of the list, any ideas anyone?

About alsa dmix, and for the record:
On an Intel(R) Core(TM)2 Duo CPU E7500 @ 2.93GHz, the following are my finding about
quality/cpu when mixing two streams at 44khz:
a snippet from my .asoundrc
#converter "samplerate_best" # perfect: 16%cpu, maybe overkill
#converter "samplerate_medium" # almost perfect: 6%cpu
#converter "samplerate" # good: 4%cpu, definitely usable
#converter "samplerate_linear" # bad: 2%cpu, way better than default wine resampler
#converter "samplerate_order" # very bad: 2%cpu, like the default wine resampler
Here is the reference topic: https://bbs.archlinux.org/viewtopic.php?pid=942724
I may be wrong, but in an opensource world (code reusing), i really doubt pulseaudio could lead to better quality/cpuuse tradeoff.
Pulseaudio, being just another layer atop of alsa, could only lead to higher cpu usage.

Can not change sound output. Help Please

Well, i've been digging all the forums lately in web. my problem is, i can't change my 'system' sound output to my sound card which is Native Instruments Audio8 Dj.
Let me explain my problem decently. I do the usual procedure, system preferences > sound > n then select the output. but nothing happens. it is always set on internal speakers or headphone or whatever plugged in to the *Built-in Output*. I try switching from audio-midi setup n that doesn't work as well. The system perfectly recognizes the sound card, i can get output from sound card with applications which have their own output settings. But i cant change the system output. I have the latest version of soundflower loaded(this might be causing the problem who knows), i used many soundcards before(or maybe even ex-drivers?) n they used to work until i updated to snow leopard. I also tried trashing the files in macintosh hd > library > preferences > audio >>
and those files *did not regenerate* after restart(like 10 times), so i had to copy them from my imac.(hehe). i tried resetting pram or nvram.(didn't do any good too)And also i tried trashing soundpref.plist which didn't do me any good neither. Now i need that sound card to give me my system output. I don't need drivers of any other ex-sound cards or whatever. My drivers are up to date. And im pretty sure this ain't an hardware fail.
So, any ideas? Thx.

I am having the exact same problem. I have spoken with Apple Care and they are having my case reviewed by "Engineers," apparently. Its very frustrating as I cannot listen to iTunes or any of my video games through my really nice monitor speakers. FYI, I had this problem without installing Sound Flower, since then I have installed it in the hopes that having something different to select it might work but no changes. If I hear any good news from Apple I will be back to let you know. This seems to be a very rare problem as I have only found one other post about this issue.

Hi legendary92,
Welcome to the HP Support Forums, I hope you enjoy your experience! To help you get the most out of the HP Forums I would like to direct your attention to the HP Forums Guide First Time Here? Learn How to Post and More.
I saw your post regarding the motherboard problems. If the HP service centre has told you that audio port is damaged you will have to replace the motherboard if you want sound. Page 75 of the Maintenance and Service Guide will show you how to replace it. The part number for your motherboard or system board as they are called in notebooks is 683031-501. You can order the part from HP PartsSurfer just search for the part number.

No sound output to TV using Apple dock - video is fine

I'm baffled. I have a new 80GB iPod Classic, a brand new Apple dock, and Apple A/V Component cable. When I watch a video or photo slideshow, everything works great. However, when I want to listen to my iPod's music through my TV's speakers, using the same setup, there is NO sound output to the TV at all. Why would the audio play when watching photos or video, but no sound when all I want is music? Please help!

I haven't personally had this problem, but I believe in order to hear music through your TV speakers, you have to use the headphone port instead of the AV cable.

Is there a way to force A Mini to recognize the HDMI as a sound output.

Is there a way to force the Mac mini to recognize the HDMI as a sound output? I have the HDMI going through a matrix switch and the video works fine but the audio is not recognized. My Apple TV has no problem with both audio and video through the same set up to a tv.

Some general checking:
Open System Information found in Applications->Utilities.
On the left side under hardware, click Audio. In the right
pane, Expand items if necessary to reveal the contents and
see if there is an HDMI listing. If so, click on it to get additional
info.
Also, have you connected the Mini directly to the TV? Narrows down
if it is actually the Mini or just how the Mini is working with the
switch.
Another possibility is that there is a power up sequencing issue.
Ran into a situation with my Yamaha receiver, Mini, and Samsung TV
that if things were not powered in the right sequence I could only
get two channel audio and sometimes only internal audio. With my
setup, I needed to power up the TV (waiting for it to come up completely
showing the searching for signal box), power up the Yamaha, then finally
power up the Mini. Also, after all this, if anything was switched, I would
end up having to reboot the Mini to get audio the way it should be.
