Why no sound?

For some reason, iChat doesn't make the "you just signed on", "recieved message", and "sent message" audio alerts. The settings were not changed, and they're where they should be. What's going on here?

Hi,
When was the last time you had the computer On and Awake overnight to run the Cron scripts ?

When I call someone using FaceTime from my mac, they can see me but not hear me. Is there something I need to do to make this happen? I also have an iPad 2 and FaceTime works great on it if I call somebody. Why no sound from my mac FaceTime using a mac pro and isight camera, mike combo.
If I use google it works. If I use Ichat, it works. If I use skype it works.

This sounds like something similar to https://discussions.apple.com/thread/3388112?start=105&tstart=0.
Try turning down the speak volume (System Preferences->Sound->Output->Output Volume) or the microphone gain (System Preferences->Sound->Input->Input Volume). Do this on both sides of the call.

Any ideas why the sound only works on about half of my apps?

The problem of tracks becoming de-linked between iTunes and the music files in your iTunes music folder happens for different reasons - this seems to come up fairly commonly in this forum.
The solution can be to locate each song in the iTunes library, as you mentioned - or, but wait, before I get to that...
trouble finding the original track in your iTunes music folder? maybe look for it under compilations, or if not using the 'group compilations preference' then look in the folder under the songs artist name, but what song artist name iTunes uses depends on what you have in the metedata tag spot for album artist or song artist. Any varyation in artist name spelling, in the menu item 'get info' metadata for any selected individual track will cause iTunes to create that as a separate artist folder in the library, even names like 'various' or any difference at all (even the word 'the' can change where in your iTunes music folder a track gets placed by iTunes). You can try to use the finder function of find file (finder munu item outside of iTunes) to locate hard to find items.
Back to how to re-link any de-linked tracks .
There may be scripts that can help re-link de-linked music files - or, at least provide you a list of such files, Scripts are easy to install and use...
at Dougs Scripts, there is one called iTunes Track CPR that might work
http://dougscripts.com/itunes/scripts/ss.php?sp=itunestrackcpr
or, if you just want a list of de-linked tracks, go to
http://dougscripts.com/itunes/
and find the script called List MIA's, this will create a text file listing all de-linked tracks
if you review the thread at

you may find more insight into dealing with this kind of issue there, although some of that thread may not apply to your case, aspects of it might help.
Good luck.

Why the sound only is reproduced by one of the headphone

Try another set to see if the headphone jack is defective.

Why would sound distort thru Apple TV

Why would sound thru an Apple TV to either my home theater or whole house audio, as well as playback from an iPad thru the home theater be outrageously distorted? Sound sources include iTunes and a plugin for Indigo 5 (home automation) and the voice Serena for announcements.
Everything was working fine until about three weeks ago, when the distortion started. For several months it had all been working great.
Any help, much appreciated.
Thanks,
Rob Z

AppleTV can output audio via HDMI cable, optical cable (if your amp has an input I'd recommend that) or analogue RCA sockets - these are a pair of red and white sockets - left channel generally goes on the white connector, right channel on the red.
There are separate RCA sockets for component video - the component term applies to video not audio so do check you're connected to the audio sockets not part audio part video.
I assume you have a lead with 2 RCA plugs at each end connecting to AppleTV and amp at the other.
By monotone do you mean sound only from one speaker or that it's the same from both i.e. mono not stereo?
I suspect you mean sound from only one speaker. If you get sound from both with other sources on the amp then that excludes an amp to speaker connection issue or a faulty channel on the amp. If this is the case then you may have connected incorrectly to AppleTV or the amp, only have a single connector on your lead or have a faulty lead. It's unlikely but the input to the amp could also be faulty so if there's a spare input try another or swap for testing purposes.
Do not connect to a phono in on the amp as it is a much more sensitive circuit and will sound loud and distorted. A CD, tuner, aux, tape in, TV or similar input should be fine.
If your sound is mono not stereo then either you have a mono setting on the amp, or have possibly encoded music as mono not stereo.

When headset is inserted, why does sound continue to come from the speaker?

When headset is inserted, why does sound continue to come from the speaker?

Sure your inserting the headset into the Headphone Out port and not the In port..?
Also what headset....?
Most PC based headset with built in mic's will not work without using a device like the Griffin iMic.

Why no sound from rear speakers (Xfi X

Vista 32bit, CMSS enabled, why no sound from rear speakers with music? XP no problem at all, only in Vista. Using latest drivers (v2.5.0004).
I realize I'm hoping against hope to get a useful answer at the Creative forums, but I do believe in miracles and the odd one happening once or twice in a lifetime, lol.

Well, I think I have an answer, from Catherina-CL's Audio in Windows Vista post. 2.The Vista audio architecture changes the way per-stream audio processing works, which required us to write new software to support this
Issues that may be encountered:
CMSS no longer works on audio streams from the OS.
Status:
Features based on Windows XP architecture must be rewritten to conform to the new Vista architecture, and we have a team of software engineers, project managers and testers dedicated to this task in order to provide our customers the same seamless audio experience under Windows Vista that they enjoyed under Windows XP. However, I found a somewhat crappy solution, at least with my old Altec Lansing 4 speaker/ subwoofer system. Unplug the surround cable from your subwoofer (unplugging it from the card itself has no effect). That at least will make all the speakers work, even if it's not true surround. Good for listening to music loud.

Why wont sound play though my TV using HDMI anymore?

Everything worked fine until the power went out one day. Now I can't get sound to play though my TV using my HDMI cable. I have tried fiddling with every setting there is to make it work on both my TV and my imac but nothing seems to work. When I open system preferences there is not any other options for output besides Internal speakers. The speakers on my TV work fine I have tested them. I've tried several different HDMI cables but nothing works. Why would everything work fine one day and then stop the next? was is because of the power outage? can I fix this myself?

You probably can't because it looks like your MacBook Pro is too old to carry audio over HDMI. You will need to run a separate audio cable from the audio out port on the MacBook Pro to the audio in port on the TV.
Check your MacBook Pro model year against the list in this Apple tech note:

Why audio sounds different in the Mountain Lion over 10.6

Hi
I just upgraded my system OS 10.6.8 to the latest 10.8.4, and I found that audio on the 10.8.4 sounds different.
I did some tests and I can say that audio when listening on the 10.8.4 has less bass content and the hi-mids are more agressive.
I running the audio studio on my Mac Pro and this was a big dissapointment for me.
Also I rendered audio file from Logic Pro 9 on the both system and they are the same, but when you listening on the 10.6.8 it sounds correct while on 10.8.4 sounds different. I have the same audio drivers from RME Fireface 800 on both systems. In tests I used identical Logic arrangement file on both systems.
I just don't like the sound on the new system at all. It is worse than it was on the 10.6.8.
I switched to the Snow Leopard again and I regret that I puchased your latest OS. Why it is done? Apple?

This may be a topic for either of these other Apple forums to discuss: Other Pro Audio, Logic Pro

Why is sound out of sync when I burn a DVD?

I finished a movie in iMovie 4 as I always have and opened iDVD from iMovie. After creating the opening title and burning the disk, I discovered that the sound was slightly out of sync with the image. It was fine in iMovie. Any ideas what went wrong?
Richard

Welcome to the forums.
There can be sync problems if the original video was
captured in Long Play mode or the camcorder's audio
quality is on the lower setting. You can search the
forum for other solutions, but one option to try is
Extracting the audio in iMovie. This will make a
copy of the original audio and put it on one of your
audio tracks (and mute the original audio). The
copied audio often will behave better.
John
Thank you, John-
Your suggestion about extracting all the audio worked. My latest DVD burn was in snyc.
I am still confused as to why such a workaround is even neccessary. I have never had this problem of out of sync audio with any other projects. Why it suddenly happened is a mystery to me. I'm very happy your suggestion worked but it is rather labor intensive if it has to be done on every project from now on.
Any ideas out there?
Thanks again.
Richard

Why the sound from Apple tv2

Why is the sound from my Apple tv2 so much louder than the sound from the tv/pvr; both are connected with optical cable to the same amplifier.
GH

Because the 2 manufacturers of the device have their own ideas of where 0db should be. Does your amplifier offer input trim? if so use it.

Why does sound fade as I play guitar?

whenever I play my guitar plugged in to garage band, on the mac, it seems to fade in sounds I play continuous notes. I also get feedback on the distorted guitars. Any ideas why these things are happening? I'm going through a Tiger Ico2- wh

Thank you Ann for answering that fast. Yes. It does look normal when paused and rendered. As soon as it is unrendered, it will go to 50 % size when I play it.
Can I change the settings somewhere for unrendered footage?

Why are Sound and Vibration Toolset examples missing?

I have installed the November Developer Suite CDs, the full Sound and Vibration Toolset and appropriate NI-DSA/NI-DAQ drivers for my PCI-4552. Why aren't all the SVTXMPs found? Specifically, Engine Run-up and Transient Analysis examples are missing from Labview->Find Examples->Browse->Toolsets and Modules->Sound and Vibration.

I think the examples are there, they've just been installed in a different path from the one the "Search Examples" app is looking for. Try:
C:\Program Files\National Instruments\LabVIEW 6.1\examples\Sound and Vibration\Transients Analysis
This should get you to the examples your looking for.
