Lion Sound Issue measured.

Hello
I have bought new MB Pro 13" /Lion 10.7.3/ few weeks ago.I am sound engineer and i decided to use digital output to connect notebok to my studio setup.
I noticed that sound is ugly, scooped and undetailed. I`ve been trying different soundcards but it didn`t change quality of sound.
I decided to measure what exactly is coming out from MB audio card. I used pink noise and SatLive measuring software. In the window, pink noise should be completely flat, as You can see it is far from flat, has scooped hi-mids and huge bump in highs. This is completely useless in pro world and even my girlfriend can listen difference between my MB and Her /the same model but older OSX/.
I am dissapointed, tried every tip I found online...any ideas?
Bart

Ok, this is the answer:
I erased OS partition and and instaled Lion one more time. Sound is clean.

Lion Sound Issues

I am having problems with my headphone jack sound output, it is distorting and clipping since upgrading to 10.7
I have checked other places, and they recommend Audio Midi set to 32Bit, but I do not have this option available, and have tried all the available variants, please can someone help me with this rather annoying issue.
Thanks
Darren

I am having the same analog sound issues with both standard audio out and headphone out. And like you I have 16-24 bit but no 32 bit Audio Midi option.

Thunderbolt Sound Issues?

Is anyone else having problems with the Thunderbolt Display and sounds. Mine works fine unless I am transferring a lot of data to my Thunderbolt drive through the monitor. When I do that, it becomes totally unusable. It almost seems like a bandwidth issue on the interface.
I am running data to a Promise Pegasus R6 (12TB) unit.
I have the same sound issues when I play any music or movie. If the data isn't running it's fine.
I am totally up to date (patchwise) on the latest 17" mbp running lion.
Any ideas how to fix this?
Thx

droids use batterys..
I don't know what issues you are having with voice though sorry

Sound Power Measurement with 4472

Is onboard DSP a must for any Sound Power Measurement?
I know that NI-Sound Power Plus works only with 455x.
Is it simply because NI has not yet written a software for Sound Power Measurement using 4472 or is it technically NOT possibly to do Sound Power Measurment using 4472?

1. The 6036E is a "sweet" card for high-speed, high-accuracy DAQ on the PCMCIA bus. Even at 10-times oversampling you can achieve 15-20 kHz of response with nice line resolution in the FFT. My experience with the PCMCIA bus has shown a wild variation in DAQ bandwidth (IBM/Compaq...the PITS -- Dell...the best ; and , no I do not work for Dell). For signal conditioning, I use SCXI (so I can not comment on the use of the other components). If you can live with interchannel skew, the set up looks quite promising. Our DAQ requirements demand the use of simultaneous sample-and-hold (SCXI 1140) for either two-channel hot-film measurements or multiple sound pressure measurements with precise cross-correlation (to eliminate wave reflections and e
chos within the test article). Our microphones were developed by NASA for use in VERY HIGH temperature environments, so our signal conditioning ahead of the 1140 is made from custom devices.
2. It is important to note that any toolkit add-on to LabVIEW "could" be written by the end user using the very same subVIs distributed with the Full Development System. Sound power is merely a term used to describe a particular mathematical method involved in transforming the acquired sound data from the real domain to the frequency domain. The mathematical methods have been used for many decades. I use my own custom code originally developed in FORTRAN, converted to C++, and now embedded in a code interface node (CIN). The issue to resolve comes down to a) do you have the in-house capability to write and support detailed code development, or, b) do you purchase the toolkits and thereby achieve the capability very quickly. Although the toolkits are expensive, the burdened cost of, say, 1
additional highly-skilled employee could cost 20 times as much.

HP Envy 4-1215dx Sound Issues

Hi, I own an HP Envy 4-1215dx. It's a great unit overall, but I am having problems with the audio on it. From the day I took it out of the box it will randomly spew out quick bursts of buzzing/crackling/digital noise whenever I try and play some sort of media, it will appear to have stopped for a while but then start doing it again, it is quite intermitten. It does it with sound from the internet such as youtube, playing MP3's, and even in Games. It is extremely irritating and I need to find a solution. I have already uninstalled and reinstalled the audio drivers and have had no luck. Doing a quick google search, I found out that there are several other people with the same problem, yet the only answer they get back is to reinstall the drivers. I have done this already and it does not fix the problem. Any help would be appreciated.
Thanks!

Hello Livingedge,
I understand that the driver is an older version. This is the version that is available for your specific product on the HP Driver & Software page. I have been able to locate a driver that is also IDT, but the release date is 2013-09-30. I have included that driver here for you 'IDT High-Definition (HD) Audio Driver'.
If this driver fails to resolve the sound issue, I would keep an eye on the 'HP Driver & Software' page. This is where if and any updates are available, will be provided here.
Thank you.

I just restored my 13" MBP i5 at the apple store to the newest version of Lion after issues with a previous Time Machine backup from Snow Leopard- this time I created a new account and just ported files and folders, and now MS Office doesn't work. Help?

I just restored my 13" MBP i5 at the apple store to the newest version of Lion after issues with a previous Time Machine backup from Snow Leopard- this time I created a new account and just ported files and folders, and now MS Office doesn't work.
^^ that's the main problem. Here's the full history.
I bought a new 13" i5 MBP, early 2011 edition. I had an old white Macbook 2.14 ghz core2duo on Snow Leopard. I attempted to port over my time machine backup, but encountered problems in that my User was inaccessible from the new computer after the import finished, and I had to go in and change the root password, etc, and for some reason or another, I couldn't install any programs at all from that administrator's account. By "couldn't" I mean I could install them, but upon installation they would never boot. So, I took it to the apple store and did a clean install from the most up to date Lion OSX. Then, I created a brand new admin account, instead of trying to import the old one, and things seemed great. Then, I just imported my old files from the TM backup, but not any system settings, permissions, or user data. Just my Docs, pics, vids, apps, and itunes stuff.
Here's where things get weird again. I imported this stuff under the name "old", but all of these folders have a red negative sign on them, marking them as restricted. So, from my main admin account, I cannot even peruse these folders. Since I didn't import user data, I can't sign in to the "old" account to change permissions. I already tried to change the permissions from system preferences, but that didn't change anything. And now, for whatever reason, of all the apps that were imported then, MS Office is the only set of apps that does not work. When I click on it, it just says there was a problem and asks if I'd like to send a report to apple. I tried reinstalling it to no avail. I'm an English student, so i really need access to Word. Can anyone help? The Apple store is a major detour for me and would like to fix this issue myself.

Most likely you have Office 2004 which are PPC-only applications and will not work in Lion. Upgrade to Office 2011. Other alternatives are:
Apple's iWork suite (Pages, Numbers, and Keynote.)
Open Office (Office 2007-like suite compatible with OS X.)
NeoOffice (similar to Open Office.)
LibreOffice (a new direction for the Open Office suite.)

Strange sound issue on iPad2

my mom is having odd sound issues on her iPad 2 that i was able to somewhat fix. and it goes from fixed back to broken o.O
i thought it was interesting and worth mentioning, in case this happens to anyone else.
her iPad 2 is up to date on the latest iOS (5.0.1) and the issue occured while she was watching a video in YouTube. sound is totally off in all apps. in Settings>General under 'use side switch to' it is set to 'mute'. when going to Settings>General>Sounds the volume control for ringers will work and cause the ringtone to play, so it seems the speaker itself is fine. however it will only work there and for that short time. afterward sound will continue to remain off. the volume control on the side of the unit will bring up the on screen speaker icon, except it doesnt show the bar that usually goes up and down with the volume. and sometimes at the top of the grey box it will say 'sound effects'. ive also tried switching the mute on and off which changes nothing.
the one thing ive found that changes anything is the multi tasking bar volume control (double clicking the home button and then sliding all the way to the left, where it shows a screen orientation lock, brightness slider and a volume control bar). now the volume control bar is unfilled and doesnt show the dot that you can slide up and down to change the volume. however when i plug the iPad 2 into a computer (any computer seems to cause this) the volume control bar will suddenly fill and the dot will appear. now suddenly sound works in all apps and will change with the side control again as normal.
now heres where it gets even weirder!!!
sometimes when unplugging the iPad 2, after a short while volume will slowly fade out and be unresponsive again. the side buttons stop working and the volume control in the multi tasking bar will be unfilled and unresponsive. repeatedly plugging it in, going back to the multi tasking bar volume control and unplugging will eventually bring volume back. a couple times ive gotten volume to stay on and the volume bar to stay responsive by unplugging it while im in the multi tasking bar. but sometimes this is not the case.
for the record, ive tried 'turning it off and on again' and resetting all settings and erasing all content and settings (both with starting up from a back up on iCloud and PC, and starting up as a new iPad). ive used two different laptops, one with Windows Vista and one with Windows 7. the iPad is synced with one laptop but aside from using iTunes to back it up and for charging, ive not made any changes to the iPad using these devices. during the entire duration of my attempts to fix it, the iPad has been on no lower than 80% power. ive also called Apple and discussed this with an Apple Care representative. who suggested all the same things id already done, and walked me through all the fixes to make sure i didnt skip anything.
hopefully and most probable is that its just an issue with iOS 5.0.1. i also have an iPad 2 thats up to date with 5.0.1 and ive not had this issue, YET.
i just thought it would be beneficial to the community to share this issue and get word out that this is happening. i would like to hear everyones thoughts on this issue and if this has happened to anyone else. the Apple Representative that i spoke to had not heard of or had to deal with this issue so it sounds like its rather new or rare. though she did mention that this is not normal behavior for the device and might be a software issue.
id like to conclude with my love for Apple, and how user friendly iDevices are in general. ive had iPods from the very first generation and all of them still work (though the older ones cant be updated past a certain iOS). the few issues ive ever had were easily fixed with a visit to the Apple Store or searching on the Apple Support Communities. so as with before, i will remain positive and look forward to a bug fix in the next update.
-thanks in advanced for reading, and any comments

Have you got notifications muted ? Only notifications (including games) get muted, so the iPod and Videos apps, and headphones, still get sound.
Depending on what you've got Settings > General > Use Side Switch To set to (mute or rotation lock), then you can mute notifications by the switch on the right hand side of the iPad, or via the taskbar : double-click the home button; slide from the left; and it's the icon far left; press home again to exit the taskbar. The function that isn't on the side switch is set via the taskbar instead : http://support.apple.com/kb/HT4085

Sound issue on iphone 4 - 7.1.1

My mom has an iphone 4 that was handed down to her from my sister. After one of the ios updates...can't remember which one...the phone stopped giving audible notifications for text messages. As I have tried to troubleshoot this issue I have discovered the other following problems:
The phone will not play music on any speaker. I was trying to connect the phone via bluetooth to a speaker bar and when I tried to play pandora, I got nothing. I then disconnected the bluetooth to see if I would get sound out of the phone's speaker and got nothing. I attempted to play a downloaded song and got nothing.
I then tried to see if I could find other issues and I did. When I go into settings>sounds>ringtones I can switch ringtones and hear the ringtone sample. When I go into settings>sounds>text tone, I can select any tone in the list and all I get is a vibration, no sound at all from any of them.
I also found that when pressing the volume up and down buttons on the side of the phone do not produce the pop up box that shows volume going up and down
I believe these three problems to be related as some kind of systematic software bug. Can anyone confirm this or offer a possible solution. Keep in mind the phone does make sounds when someone calls also from the speaker phone. The only non-sound issues are text notifications and playing music. I find this to be a rather important problem because the phone can really no longer be used as a phone since my mom continually misses text messages because she does not get an audible notification.

Hello hiknmt06,
You may need to restart or reset the device.

Windows Vista major sound issues

On my 2 month old Unibody Macbook, I'm experiencing severe sound issues with bootcamp 2.1 in windows vista. While playing games such as Halo 2 or Fallout 3, which the macbook graphically handles exceptionally well for a laptop, the sound crackles and often disappears! To get the sound back I have to reboot my macbook. Help, this is extremely annoying, and apple won't do a thing about it!!! Please help!

Sound issues with MacBook Pro

I am experiencing sound issues with my MacBook Pro. I am using a headset and when I am on a skype calsl I have a hard time hearing the other person, the sound is coming in and out and sounds digitized. This issue only started recently, the sound had been working fine for years before this issue.

I do not use Skype, but may be information from the below linked article helpful.

Sound issues in iOS6

I'm having random sound issues since upgrading iPhone to iOS6. For instance, after using iMessage I will sleep the phone without exiting iMessage. 5 mins later I will have messages sent to me but there were no sound notifications indicating such. Only if I exit iMessage prior to sleeping the phone will I hear notifications of new texts or iMessages. Also, random sounds like the swoosh when sending an email will mute randomly. I have to shut the phone off and restart before it works again. Why is this happening?

If you have a iMessage open and into a message, normally it will not sound. I think it is because you already have it open and in it. That is what I have noticed.

What is a packet problem? I'm having sound issues.

I'm at my wit's end. I am having sound issues. I've run diagnostic tests and everything comes back as OK, but it's not OK! Something somewhere is messed up and I can't figure it out.
I have been to the help rooms on paltlak and opened up support tickets and everything they told me to try has not helped. They suggested I change the sound tuning on my chat program, change exceptions on my firewall, uninstall and reinstall chat program, uninstall and install earlier version, download drivers for sound card, and etc. Nothing is helping this problem.
Someone mentioned that it may be router problems or packet problems. I'm not sure what that means, and that is why I'm on this forum asking for help. I have no other sound problems on my computer. My music and videos play fine. It's just when I'm in a voice enabled chat, do I experience these problems, or if I'm on a website that has videos, the video will not load all the way, so I only get 30 seconds of a video. Does anyone know what could be causing this?
I have used this chat service for over 5 years and up until a week or so ago, it worked fine. I did a complete reformat of my computer in hopes that it would help, but I'm still having the same problems. I lose sound within 5 seconds of entering the chat room. Then it takes between 3-5 minutes before I hear sound again, but then I only hear it for a few seconds. Then it goes away for another few minutes. Repeat. Over and over again.
I'm running Windows Vista on an Acer Aspire 380 with wireless cable modem. I keep losing sound in any voice/sound enabled chat and on any site that has videos. I have 1gig of ram, 300 gb hard drive, 32 bit operating system, 2 processor cores, directx version 9, realtek sound card. Everything is up to date, and firmware is up to date. My speed test is: download: 6.162 mbps and upload: 926 kbps.
When I do the ipconfig/all, it shows
Tunnel adapter local aera connection* 6: Media State: Media disconnected
description: teredo tunneling pseudo-interface
dhcp enabled: no
autoconfiguration enabled: yes
I don't know if this has anything to do with my sound issues on the chat program or not. ??
Also shows:
node type: hybrid
dhcp enabled: yes
autoconfiguration enabled: yes
default gateway: 192.168.1.1
dhcp server: 192.168.1.1
netbios over tcpip: enabled
If by chance it is a packet problem, how do I fix that?

Hi. Thanks for the quick reply. Yes, it just started recently and after not being able to fix the problem, I completely reformatted my computer and started with a fresh slate, but still having the same problems. The videos will not continue to load. They get less than half way and then just totally stop loading, therefore I only get to view the video up to the point where it stops loading. I just took your advice and I disconnected the router and connected my computer directly to the modem and my sound issues were fixed. I went into the voice chat and had sound for over 10 minutes (and then I disconnected) instead of the usual 5 seconds that it'd been. So is it the linksys that is causing this? If so, how can I fix it? Thank-you. Message Edited by nightrider7000 on 01-22-2008 11:34 AM

Macbook sound issue after standby

Hello,
Bit random issue here..
This is not consistence but it is totally random. Randomly when i open the macbook lid when it comes out off standby by i hear a weird "ripping" sound issue i think its coming from left hand speaker or side. Im assuming its the speaker.
Its hard to explain its starts with a weird fuzzyness and then it turns into a rip type sound and stops.
It last about 2 seconds and is random and only happens after putting up lid.
Is this normal? any ideas?
thanks

Upgrade kernel to 3.1.5 still not fix the sound issue
On 12/14, I upgraded imagemagick, pcre, texinfo, virtualbox-modules, wxgtk with `pacman -Syu`,
after reboot, the sound comes back, everything works fine just like before
But on 12/16, I lost the sound again, only found these line in kernel.org
Dec 16 09:28:29 localhost kernel: [75508.452468] ice1724: Too long irq loop, status = 0xff
Dec 16 09:28:29 localhost kernel: [75508.452468] ice1724: Disabling MPU_TX
no matter how I tried to reproduce the upgrade on 12/14, still unable to fix the
issue, and those warning didn't show up again, I also boot into live USB to check
if this is hardware problem, but sound works normal in live USB
it's so weird...

GTA San Andreas is working fine, now since 2 days i have Battelfield 2 and there is an enourmous sound issue...you play the game a bit..all of a sudden(before fluent gameplay,no problem)sounds start to stuck alot when you listen to the guy talking to its like hes talking in slow motion and the whole sound starts to get grazy...and the performance drops then down to a level where the game is just not playable...me friend has this game 2 and gues what he has the same problem and last guess...he has an audigy 2...suprised?
If anyone knows this problem and know how to fix it pls let me know...
and i would like to hear from creative a statement if this is their fault or ea's?
All other games run supreme,i mean that in the soundish way.
thx in advance

I had the same problem with the radio in my game. Turn it from hardware to software mode in the audio options. You'll still get good sound, but it might run a bit slower, as it uses more memory.
