Lion to Snow Leopard missing audio during video chat

Hello,
After upgrading one of my MacBook Pros to Lion, I've been encountering a consistent problem when attempting to engage in a video chat with my parents who are using a MacBook that is still running Snow Leopard.
Prior to the Lion upgrade, video chats worked flawlessly, but after the Lion upgrade, the audio coming from the Snow Leopard machine is completely gone. Video alone works fine in both directions, and the Snow Leopard client is receiving audio from the Lion client, but the Lion client is not receiving any audio from the Snow Leopard client according to the iChat connection doctor.
Not a missing update/firmware issue-
Both machines have all the latest OS updates applied.
Not a hardware deficiency issue-
Both machines were able to engage in flawless video chats using iChat prior to one machine being upgraded to Lion.
Not a bandwidth issue-
MacBook Pro (Lion) is hard wired to an ethernet connection which ties into a fiber optic connection 100Mbit/100Mbit (down/up).
MacBook (Snow Leopard) is hard wired to an ethernet connection tied into a AT&T Uverse connection 24Mbit/3Mbit (down/up).
As a troublshooting step, each machine was tested with iChat bandwidth limitation set to 500k, 1Mbit, and 2Mbit.
Not a ports issue-
As a troublshooting step, both machines were placed into each respective LAN/WAN DMZ.
Not a firewall issue-
Both machines are not running with a firewall enabled.
Not a network configuration issue-
Video chat continues to work flawlessly between Snow Leopard only clients from the same networks over the Internet (tested with additional Snow Leopard clients on my end that have yet to be upgraded to Lion).
Not a microphone or sound configuration issue
First thing checked, double checked, and checked again.
After checking the connection doctor within iChat during one of the problematic video chats, it reveals that "audio quality" from the Snow Leopard client is always 0%.
Has anyone else encountered this problem? Moreover, is there a solution?
BTW, Facetime video calls between all clients work fine, but we all hate Facetime and prefer to continue using iChat.
Any help would be sincerely appreciated.
Thank you.

Hi,
SoundFLower is an Add-on to the System that then appears in the System Preferences > Sound pane as well as being an App.
It allows the Mic (or input device) to be used by two apps at once.
It can also take the output of one app and get in to another.
Sound.
IN certain versions of iChat and with certain Headsets you can have issues if the iChat is set "first" the the System Preferences are set Second.
In both iChat and System Preferences > Sound > Input chose any other device/input other that the propsed headset.
The chose the Headset's mic for the System Preferences
Now set the mic for iChat
Repeat for System Preferences > Sound > Output and the Headphone side.
What is Arriving
Whilst a chat is going on open the Connection Doctor (Video Menu)
On the Stats tab/button you will get a live read out of Bitrate and Framerate and a visual representation of the incoming Video and Audio feed.
Bit rate will vary based on what you pay for and what the Bandwidth Settings is. (you can change it "Live" during a chat and see the Buffering change the rate slowly).
The Framerate should be at least 15fps
Intels can be higher whit 30fps being the top rate.
The Visual bars should be green and 100%
They may vary if your service varies to much.
Buffering
Any Internet service will vary.
iChat has buffering mechanism to cope with this
Earlier versions of iChat were limited by the Quicktime Streaming setting that used to be in System Preferences (Up until Leopard).
Now iChat and Messages can make use of All your bandwidth.
The Buffering will drop frames in an effort to keep up if someone is sending more data than you can handle.
There comes a point when it judges it will lose sense of the Audio due the number of dropped frames and it will cut the Audio.
If the Audio bar is showing nothing then check the Bitrate.
Let me know what you see.
Comparisons with you other computer would be useful.

Help - no audio during video chat

During video chats with another mac user, we both have video and can see each other, but neither of us has any audio. When we do just an audio chat, we can both hear each other without a problem.
This happens on my MBP with 10.6 and iChat 5.0.1 and on my PBG4 with 10.5 and iChat 4.0.8. The other computer is an iMac with 10.4 and iChat 3.1.9.
Any suggestions?

Hi,
So this is Linksys Modem that can Route with a Airport in Bridge Mode ?
Good.
IS it using UPnP (in the Administration tab) ?
If it is then Port Forwarding, Port Triggering and DMZ should be Off in Gaming and Applications.
In Security tab (if it has one) the Firewall should be disabled (If it has a setting) as this interferes with iChat.
The Bit about "Responding to Anonymous Requests (pings) should also be set to Allow them (ichat Sends a Ping).
I have had a Netgear DG634G and currently a Sagem 2504 Fast Modem that both Report "Port Restricted". It is not a deal breaker.
More interesting is that you see no incoming Audio.
Get the Buddy to check his System Preferences > Sound > Input tab has the volume high enough and the device here and in iChat > Preferences > Video Section match in the Microphone drop down.
He/she should also check the Video Menu and that Microphone Enabled is ticked.
If those things are in place then try the Bandwidth in iChat at 500kbps
(Try it at both ends, then use the Connection Doctor > Statistics to change one end at a time to higher settings - wait for the Bit rate to settle).
The Bit rates you are seeing look OK (As does the other info)
The Bit rates at the Buddies end should have got a Message from iChat that the Connection is too low (Below 50kbps) for a Video chat.
Are you sure these are from the same Conversation ?
If the Buddy is on Leopard or Below they should go to System Preferences > Quicktime > Streaming and change the setting to 1.5Mbps to get iChat to "see" as much as is practical of the internet speed.
It is almost as if they and doing a Download at the same time (Or another computer is taking all the Bandwidth)
What Internet Upload and Download Speeds are they paying for ?
What are they actually getting ?
Click the yellow star And the Start Test box.
If you are connecting in Video chat with th VPN active I don't think this is an issue (unless it is using up lots of Bandwidth - you results suggest not).
The issue seems to be at the odd results your Buddy is getting.

No audio during video chat

after upgrading to leopard, i can no longer hear who i'm video chatting to, and they can't hear me. If we switch to an audio talk only (ie no video), the audio works fine in both directions.....
any ideas please

I had this with someone trying to connect to me recently.
It turned out they were on a Wireless connection from their House to the Internet.
These type of Modems and those for Satellite connections often have a latency that means their connections start slowly and speed up to the quoted/paid for speed.
iChat needs to start a lot faster than this.
It may have something to do with iChat now using one port for all video and Audio data both In and Out.
If the Connection Doctor shows a lack of Audio in the % bar then that is the Incomming feed.

I had Leopard on may Mac. I upgraded to Mountain Lion using Snow Leopard. I can't use my video with Mountain Lion. Can I load Snow Leopard on an external hard drive so I can use it with my camera?

I had Leopard on may Mac. I upgraded to Mountain Lion using Snow Leopard. I can't use my video with Mountain Lion. Can I load Snow Leopard on an external hard drive so I can use it with my camera?

First, you cannot do this if you have a Boot Camp partition.
Second: Create a new partition.
1. Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
After the main menu appears select Disk Utility and click on the Continue button. Select the hard drive's main entry then click on the Partition tab in the DU main window.
2. You should see the graphical sizing window showing the existing partitions. A portion may appear as a blue rectangle representing the used space on a partition.
3. In the lower right corner of the sizing rectangle for each partition is a resizing gadget. Select it with the mouse and move the bottom of the rectangle upwards until you have reduced the existing partition enough to create the desired new volume's size. The space below the resized partition will appear gray. Click on the Apply button and wait until the process has completed. (Note: You can only make a partition smaller in order to create new free space.)
4. Click on the [+] button below the sizing window to add a new partition in the gray space you freed up. Give the new volume a name, if you wish, then click on the Apply button. Wait until the process has completed.
You should now have a new volume on the drive.
It would be wise to have a backup of your current system as resizing is not necessarily free of risk for data loss. Your drive must have sufficient contiguous free space for this process to work.
Third: Install Snow Leopard.
Boot from your Snow Leopard DVD. Follow instructions for installation being sure that before you actually install Snow Leopard you have selected the new partition as your target destination.
Booting From An OS X Installer Disc
1. Insert OS X Installer Disc into the optical drive.
2. Restart the computer.
3. Immediately after the chime press and hold down the "C" key.
4. Release the key when the spinning gear below the dark gray Apple logo
appears.
5. Wait for installer to finish loading.

Ichat no audio on video chat with snow leopard

Hello,
I am having an issue where there is only one way audio when doing a video chat with those using snow leopard. If I start the video chat, the other person can hear me and I cant hear them. If they start the chat I can then hear them but they can not hear me. This was not a problem prior to upgrading to snow leopard (both of us). I can video chat fine with those who have not upgraded to snow leopard.
Audio chats alone work fine with these people.
I have tried changing bandwidth settings in ichat on both ends, enable 32 bit mode, checked the sound preferences, etc and nothing helps. We are not running any third party apps that have been mentioned to interfere with ichat.
I would greatly appreciate any suggestions..
Thanks.

Hi,
Also cap iChat in iChat > Preferences > Video Section > Bandwidth Drop down to 500kbps
There is some evidence that it is the iChat Buffering.
iChat tries to buffer the Video to match changes in the Internet Speed.
Now that iChat 5 "sees" the whole of your Internet Connection (or your Buddies if they are on Snow Leopard) there can be bigger differences with a 1% slow down.
There may also be a larger difference in what your Buddy can now stream to to you as iChat is Processor/Bandwidth dependant on how big and how many frames a sec are sent/Received. (your Buddy, or your to your Buddy, may well be able to overwhelm the other).

Exporting OS X Mail from Mountain Lion to Snow Leopard

After upgrading to Mountain Lion, I partitioned my iMac HD to have two partitions: Macintosh HD has Mountain Lion; I reinstalled Snow Leopard on Macintosh HD 2. Best part: you can access your user-created files from EITHER disk partition. But not so OS X Mail. I wanted to revert to Snow Leopard, since I don't like the iOS-like Mountain Lion (swipe THIS!), but Mail was a problem since all my Snow Leopard Mail was successfully migrated over to Mountain Lion during upgrade. But I think I found a way to Export Mail from ML to (a clean install of) SL.
Try this:
1. Open Mail in ML. For each folder you wish to have back in SL, Export it to your ML Desktop as an .mbox file. Depending on the folder size, this can take from a few seconds to several minutes. You'll see an .mbox icon for the particular folder on your Desktop. If the word "partial" appears between the folder name and the .mbox suffix, wait a few moments for the Export to complete, at which time the word "partial" will disappear. E.g., for a folder named "Mary", if it's a huge one, the icon will first appear as "Mary.partial.mbox"; when the Export is done, you'll see "Mary.mbox".
2. When you've Exported all your desired folders as above, you can exit ML and re-start your Mac in SL. Open Mail in Snow Leopard, and once again, for each file you just Exported in ML to the Desktop there, select "Import Data From Apple Mail" and choose the folder from the Desktop in ML to which your mboxes were Exported. When the Import starts, you can see via a progress bar how far along it is. When done, you'll see a new folder in your SL Mail called "Import"; click on it to reveal the folder you just Imported!
3. Then drag the folder you just Imported out of the Import folder to "On My Mac" in SL Mail; you can then delete the Import folder.
4. Repeat until all your folders are where you want them (in SL).
5. When you have time, go back into ML and clear all those .mbox files from your Desktop.
There MAY be an easier way, but this is what worked for me.

The iOS view vs classic view in Mail is not the problem; I've already configured for classic view.
Mountain Lion itself is.
My short list (to date) of crappy Mountain Lion behavior; items marked with a double asterisk (**)represent the worst of Mountain Lion for me.
** No up/down arrows in scroll bar slider;
Expose` not as easy to navigate as in Snow Leopard;
Mail does not request passwords for either receive or send;
No "Save Draft" icon in Mail compose window (workaround: use command-s);
"Save As" selection missing in most app menus;
No separate Search window in Safari (workaround: use Firefox or Opera);
** Can't export Mail from Mountain Lion into Snow Leopard if downgrading (I compiled this list before I stumbled on the method in this thread, but I'd prefer to effect this with Unix symbolic links);
iWork 09 seems to have "circled the wagons" re compatibility with MS Office or LibreOffice (workaround: just use Libreoffice);

I have a Mac Pro with four hard drives. I currently have Lion installed on one hard drive. I want to have the option to boot from either Lion or Snow Leopard. How can I do this?

I have a Mac Pro with four hard drives. I currently have Lion installed on one hard drive. I want to have the option to boot from either Lion or Snow Leopard. How can I do this?

It's best to install Snow Leopard on one of the three remain drives without an Operating System.
You can then install the applications you need from the original media. Create a User Account using Setup Assistant.
Do you want to migrate User Accounts from the OSX LIon boot drive, or are you keeping the User Accounts separate?
Dual-booting just requires holding the option key during startup and selecting either Lion or Snow Leopard.

Is it possible to install Lion on the second hard disk on my Mini (2010) Snow Leopard Server, and switch between Lion and Snow Leopard? I like those voices Lion has in speech.

When baltwosaid NO emphatically, that was described as CORRECT ANSWER. Ditto in the caeses of the radically different answers from Camelotand Matt Clifton
Could it be that CORRECT ANSWER needs better defining by Apple?
That apart, yes, switching might involve rebooting. About the voices, well, I was the other day adding voice to a commentary in a video I was working on. There's only American English accent in SL — Lion I believe has British ones as well.
Why not, I wondered, try to install Lion purely for academic interest, maybe with an SD card (Sandisk Ultra II, 16GB) as Tom Nelson says is possible at http://macs.about.com/od/macoperatingsystems/ss/Perform-A-Clean-Install-Of-Os-X- Lion-On-Your-Mac.htm

Lion to Snow Leopard using Time Capsule

Hello folks. Despite all the perks of Lion, I have too many programs that arn't compatible with Lion. I don't think the downgrade from Lion to Snow Leopard was addressed IF also using Time Capsule in other threads. I'm no expert so I wanted to get details instead of piecing together random tibbits. But if I happen to miss that thread, please let me know. Thanks!

Downgrade Lion to Leopard and upgrade Leopard Lion without Snow Leopard CD

Hey guys,
Can I upgrade from Leopard to Lion without the Snow Leopard CD? I lost it.. And I want Lion or Snow Leopard back due to an image on my Time Capsule that Leopard doens't see.
I ran under Lion but wasn't happy with some of the features. I decided that I wanted to downgrade to either Leopard or Snow Leopard.
I made a back up on my Time Capsule. After it said Last back up 1 min ago I inserted my original CD (Leopard) since I couldn't find the Snow Leopard CD. I completed the reinstallation of MAC OS X and it ran super smoothly. Now Leopard didn't recognize my image (ofcourse since it was Lion) and all the work was done for nothing..
Now I really want to get back on Snow Leopard or Lion so I can reinstate my image and thus all programs and files that I now miss...
Problem: I don't have the Snow Leopard CD..... I can't download Snow Leopard and I can't download Lion because I don't have Snow Leopard... But I paid for both and I don't really want to buy both again just because I made a tiny mistake.
Any of you guys know how I can fix this??
I am now running version MAC OS X 10.5.8 and I'm getting a little annoyed! Lion was AWESOME compared to this version
Cheers!!
Max

Downgrade Lion to Snow Leopard
1. Boot from your Snow Leopard Installer Disc. After the installer loads select your language and click on the Continue button. When the menu bar appears select Disk Utility from the Utilities menu.
2. After DU loads select your hard drive (this is the entry with the mfgr.'s ID and size) from the left side list. Note the SMART status of the drive in DU's status area. If it does not say "Verified" then the drive is failing or has failed and will need replacing. SMART info will not be reported on external drives. Otherwise, click on the Partition tab in the DU main window.
3. Under the Volume Scheme heading set the number of partitions from the drop down menu to one. Set the format type to Mac OS Extended (Journaled.) Click on the Options button, set the partition scheme to GUID then click on the OK button. Click on the Partition button and wait until the process has completed.
4. Quit DU and return to the installer. Install Snow Leopard.
This will erase the whole drive so be sure to backup your files if you don't have a backup already. If you have performed a TM backup using Lion be aware that you cannot restore from that backup in Snow Leopard (see below.) I suggest you make a separate backup using Carbon Copy Cloner 3.4.1.
If you have Snow Leopard Time Machine backups, do a full system restore per #14 in Time Machine - Frequently Asked Questions. If you have subsequent backups from Lion, you can restore newer items selectively, via the "Star Wars" display, per #15 there, but be careful; some Snow Leopard apps may not work with the Lion files.
I would assume the above may work to downgrade to Leopard by using the Leopard DVD instead of the Snow Leopard one.
If you purchased Snow Leopard then you should have the DVD. If not, then you might call AppleCare about a replacement or simply repurchase it.

CAn I run Lion and snow leopard on the same computer with different sign-ins?

Alternatively, partition your internal HD and dual-boot it. Do note that you have to reboot to switch back and forth. You can't do it by logging out and back in.

IMac 2011 Lion to Snow Leopard if needed?

Hi all.
I've posted in another discussion about my gradual move over from PC to Mac and the possibility of dual booting but this thought occurred to me. I'm now looking at getting an iMac after using a borrowed mini for a few weeks but finding that multiple monitors/keyboards etc are getting in the way. Plus I need the floorspace the PC is taking up so KVMs and the like aren't really an option.
Anyway, I don't know where Apple are up to at the minute with their hardware/software combinations but if I were to buy a new 27" iMac tomorrow (I'm not: not THAT soon anyway) would it come with Snow Leopard and Snow Leopard installation discs? Would it have Lion preinstalled? If it DID would it come with any discs at all? I believe the recovery partition would handle that part of things (dead HDD notwithstanding) so my suspicion is that no recovery media would be included.
Now, what if I REALLY didn't like Lion or found it had too many problems with my other hardware (I currently have a Lacie NAS drive for example!!) is there any way I could replace Lion with Snow Leopard? Would a retail boxed version, which I think is 10.6.3 have the necessary drivers or at least adequate ones to boot and run Software Update? Would the install disc that came with the MacMini work? My first thought is no it wouldn't. Am I right in thinking the installation discs that ship with a machine are model specific? Would an iMac preinstalled with Lion even be capable of downgrading (we can discuss whether Snow Leopard is a downgrade or not another time)
Anyway, all suggestions welcome as long as they are clean.
Edit before posting: Having said all that if the rotten AppleTV/iTunes keeps losing Home Share connection and kicking me out after 10 minutes of watching a movie then I might just stay a PC user and sell the Apple stuff that isn't working to some unsuspecting numpty. Might just go over to THAT discussion in a minute and add my voice to the ones having issues.......

I suspect the person buying your equipment would be no more a numpty than the original purchaser. Ive been using Lion for some time now and it has frankly no more problems than any other newly introduced software/operating system.
I went through the Windows/PC to Apple a few years ago after much deliberation (and time wasting) I am glad I did it and would not go back. Hving said that I still have a Dell XPS Laptop that is purely used to run Quicken (Windows 7) and nothing else. I could do this with Paralells or bootcamp, but at the moment I see no point. Make the jump to Apple you will probably not regret it. Your wallet might.
My Apple TV works perfectly unless my wireless network is playing up and I suspect Apple cannot do much about that.

Dual boot drive - Mountain Lion and Snow Leopard - Correct order to load software /apps?

Hi
I want to create a dual boot drive for Mountain Lion and Snow Leopard as some of my hardware (is not supported in Mountain Lion).
I am happy how to do this, I just want to know if there is a correct way to install software and apps.
My plan was to do a clean install of both using two partitions, the larger going to ML and smaller one for SL. I was going to install SL from the DVD and then after updating from 10.6. to 10.6.8 and download ML from the app store and install on the larger partition.
Do I install all the software I use like Final Cut, Aperture, iLife (for Garageband) etc on the ML or SL partition or on both. Also, is there a better way / practise of the order software updates / apps and boxed software should be installed when doing a clean machine install.
Thanks in advance.
Matt

Thanks mende1
So, if I have software I need to use on both ML and SL - for example Final Cut as I have a Canopus AVDC box which is not supported in ML but only SL, do I need to install the same software in both OS?
I usually open apps using spotlight and didn't know if it would software / apps would open if already installed on the other partition?
Thanks again
Matt

Running Lion and Snow Leopard on the same MacBook Pro

So here's the thing .....apparently Lion won't run Photoshop and Illustrator CS2 (which I'm quite happy with and not about to shell out silly amounts of money to Adobe for even CS3) and apparently there may be (and I stress may be) problems with Word 2008 (likewise money to Microsoft for Word 2011).
I think, and probably won't know till I've installed it, that I'd like to try Lion on my Macbook Pro but keep Snow Leopard as a separate OS to run Photoshop, Illustrator and if necessary Word until I can afford to pay Adobe (& possibly Microsoft though I can't really see what improvements they can make to Word 2008) the large amounts of money they seem to think they deserve for an upgrade.
Does anybody out there know if it is possible to run both Lion and Snow Leopard on the same machine and if it is how do I do it?
Thanks for taking the time to read this.

I upgraded to mountain lion from snow leopard, now my photo studio software is no longer supported by powerpc. Does anyone know of a fix so my photostudio will work?

I upgraded to mountain lion from snow leopard, but now some of my applications do not work, most specifically I would like to use my photo studio, but now it tells me that powerpc is no longer supported. Does anyone have any fixes to this problem? I would really like to continue to use software that I already have! Thank you for your help!

PPC software will not work in Mountain Lion because there is no longer any Rosetta emulator. You will only be able to run your older software by creating another partition on your hard drive on which you can install Snow Leopard. It need not be a large partition since you can still keep your files and programs on the main partition. You could also install Snow Leopard on an external drive from which to boot the computer.
To resize the drive do the following:
1. Restart the computer and after the chime press and hold down the COMMAND and R keys until the menu screen appears. Alternatively, restart the computer and after the chime press and hold down the OPTION key until the boot manager screen appears. Select the Recovery HD and click on the downward pointing arrow button.
After the main menu appears select Disk Utility and click on the Continue button. Select the hard drive's main entry then click on the Partition tab in the DU main window.
2. You should see the graphical sizing window showing the existing partitions. A portion may appear as a blue rectangle representing the used space on a partition.
3. In the lower right corner of the sizing rectangle for each partition is a resizing gadget. Select it with the mouse and move the bottom of the rectangle upwards until you have reduced the existing partition enough to create the desired new volume's size. The space below the resized partition will appear gray. Click on the Apply button and wait until the process has completed. (Note: You can only make a partition smaller in order to create new free space.)
4. Click on the [+] button below the sizing window to add a new partition in the gray space you freed up. Give the new volume a name, if you wish, then click on the Apply button. Wait until the process has completed.
You should now have a new volume on the drive.
It would be wise to have a backup of your current system as resizing is not necessarily free of risk for data loss. Your drive must have sufficient contiguous free space for this process to work.
After you create the new partition boot the computer from your Snow Leopard DVD and install Snow Leopard onto the new partition.
