AVDHC 5.1 to Stereo Sound Issue on Panasonic SD1
When I log and Transfer in FCP 6.0.1 The video turns out fine, but the Audio the right channel is WAY louder then the left channel after conversion. Other conversion programs do not seem to have this issue. Can anyone help? I am very stuck
Also should I use ProRes 4:4:2 or AIC? What is the benefits and drawbacks to each? Thank you
I have the same issue. Tested also Sony 5.1 AVCHD cams. Same issue. Same 5.1 to wrong stereo downmix from AVCHD cams in iMovie 08.
Reported and discussed with 2nd line support from Apple. Seems to be known issue. They appear to be working on solution.
A workaround: connect a mic to the cam and it starts producing stereo files. These import well.
A small mic is the ohrwurm2. Have a look on my website at Oktober Gadget: http://www.thegadgetman.nl

Strange Line In problem with my X-Fi Elite Pro. Stereo sound comes and goes
I have an X-Fi Elite Pro with latest drivers installed. Everything works fine, except for the Line In port in Entertainment mode. I have an AverMedia TV/FM card and its audio output (stereo) is plugged in my X-Fi's Line In/Mic In (PCI). The problem is that I get sound only from the right channel but not from the left one, so the sound comes out in mono. From time to time, I get to hear in stereo (both channels) but it seems a random event. This input works just fine in Game and Creation modes btw.
Stereo sound from this particular input comes and goes in random order and sometimes I get about 50% on the left and 00% on the right channel. Sometimes, left channel volume fades in and out slowly. I already did some troubleshooting such as set Line in/Mic In/Digital In to "Line In/Mic In", speaker diagnostics, checked it in Game & Creation modes, turned to default values and so on but I still get this problem.
Seems pretty wired. A ghost in the machine! Creative products never seize to amaze us!Soo...your're calling me stupid? Well, perhaps your right, but then again, I might have a point!
Read my post again.
If you still think it's too low with SVM enabled and everything is turned up...then I'm affraid you're out of luck and might consider buying another speaker set, if it's a major issue to you. -
guys after a long time...i finally shifted to mac ...a long time windows user...so far the experience is been good..
ok here is my first problem with this setup
in india its a pain to get a toslink to mini adapter ...finally i found one and connected the mini end to headphone jack behind my imac...
(imac 21.5 mid june 2011) and optical end to my hometheatre ...
in audio midi setup the multichannel option is set to stereo 2ch 16 bit..
perian is installed and set to use dolby prologic..
i only get stereo sound from itunes,vlc or movist or even xbmc and boxee...tried them all configured the audio to use 5.1 but no luck,
questions
why is 5.1 greyed out ?in audio midi setup ?
i am using my mac to create multimedia content and knowing how the sounds created will be heard helps me a lot..
i have invested a lot (3 years savings in this mac) and i wouyld very much appreciate all your help..
i also purchased a griffin hdmi port which connects to my tv but the audio is still stereo..
finally got a toslink http://www.amazon.com/3-5MM-TOSLINK-FIBER-OPTIC-TOSLINK-mini-Toslink/dp/B00006LV F3 this one ...still only stereo...
any help would be greatly appreciated .....Hello John, I figured it was a signal issue. All the speakers fire and the sound is great. I was running the speakers thru a Dell PC with a Creative X-Fi Elite Pro, THX Certified, 7.1 soundcard using a fiber optic from the Mac Pro to the Z906's, it worked great until the Dell died!!! When I bought the soundcard from Creative I also bought the GigaWorks S750, THX Certified, 700 watt, 7.1 speaker system, used the speakers for 11 years and then the woofer/amp said "I QUIT" Creative quit making the speaker system and the sound card. The satellite speakers from the Creative GigaWorks speaker system still sound great (rated at 78 watt each) and are a little better speaker than the one's that came with the Z906 and the wattage from the 906 is sufficient to drive the satellites without any distortion. Thank you for addressing my issue, you confirmed what I suspected all along, just needed to hear it from someone with the same setup.
One last question, I purchased a Diamond Multimedia USB Soundcard, can't use the fiber optic(not supported by Mac) but the green, tan and black RCA's plug in and produces adequetly. When you plug your 906's into the Mac Pro using the fiber optic how do you set your speaker configuration? When I plug into the mac pro with fiber optic the 'Audio Midi Setup' does not seem to see the 5.1 configuration. Any thoughts there?

ATV2 Sound Issues - known workaround?
Hi there
I'm also having still some sound issues with my Apple TV 2 (using latest firmware and iTunes Release running on a Mac mini Server)
The ATV2 is connected by HDMI and Toslink to a DENON receiver. I do have a library of movies converted from DVD using Handbrake with standard Apple TV 2 preset. This was including a AAC Prologic Stereo downmix audio track and usually a AC-3 passthrough 5.1 suround audio track. Since the 4.4 updates i don't have Dolby Digital sound anymore and optical output is only working when disconnect HDMI.
With the older firmware 4.3 i did not had any problem!
I found this workaround to reenable Dolby Digital Sound output:
1.) Go to the audio track selection menue by pressing select button, switch to audio selection menue switch manually to the second audo track still having stereo downmix (should be the AC-3 track.
2.) Repeat procedure to switch back to the first audio track -> ATV switches AC-3 to HDMI output!
This works on all my handbrake coded movies including aac stereo and ac-3 5.1 audio tracks. It has to be repeated when changing movie.
This is clearly a newly introduced software bug, please fix it!
ThanksWell fact is, that all movies have correct sound AAC and AC-3 tracks using handbrake 0.95 standard Apple TV 2 preset. None of these movies had any issues with previous ATV2 4.3 firmware releases.
Furthermore the Issue can be corrected by simply switching audio track selector in ATV2 twice novadays!!!
While investigating the problem I had also the idea of some mistakes in the movies itself. So i used Subler and mediainfo to check the video files. Then used Quicktime, iTunes and VLC to examine content and could really not see any problem with m4v files.
VLC can correctly switch audio track because it can decode AC-3 DD 5.1 streams internally.
Quicktime locks like decoding both audio stream simultanously (has no switch to select) causes strange echo.
iTunes shows the two audio streams in menue but won't let you switch to dolby digital (greyed out) implies, that it neither can passthrough nor decode AC-3 DD 5.1 tracks.
I also saw, that with the 4.3 firmware i could have sent DD 5.1 to the optical output, even with connected HDMI cable, which is definitely not the case anymore.
Still need to be fixed! -
Random switching between mono and stereo sound on t400s

Don't pm me for help! That's what the forum is for. Also, Google's nicer than me. Ask him.This issue seems to be similar to the "T410 Extremely Annoying Audio Issues" thread, have you tried potential solutions there? (Can't summarize it because I haven't read the thread.)

Stereo mixer issue on last CC oct 2014
Hello,
last version of CC oct 2014 seems to have a stereo mixer issue.
When you apply it to an audio file, if you put keys form 100 to 0, at 0 the sound that you can hear pop up to 100, even if the key is at 0...
I add an issue report, but nobody answer.I upgrade this post with more tests i've done:
I've tried a timeline with a separated workstation, completely isolated and a local storage.
An iMac 27", core i7 and 8 GB Ram.
I've placed a timeline 1920x1080 p50 and tested with multiple Operative systems.
The Ram consumption is the same on both Mac OS 10.9.5, 10.10, and 10.10.1 while it's slightly better on 10.10.2.
Is it possible no one ever noticed this issue, or i'm missing something? -
5. Surround Sound Issue <span class="Apple-style-span">This is very odd. I've just bought a PCI express Sound Blaster X-Fi Titanium Sound Card and hooked it up to my pc. Next i got a digital cable and ran it from the xbox's Composite cable which has a socket for the Digital out and then put this into my sound card into the digital in. Next i turned on my xbox with the computer running and speakers on etc and i had full 5. surround sound for the intro xbox 360 video, now that i'm on the dashboard i have got no sound at all, and even when i went onto a game again i had no sound. Why would this be happening, every time i turn the xbox on the intro vid always has 5. from my speakers(these are running out from the sound card) and then after it always goes silent. Any ideas on what i can [email protected]
I want to share an update in case it helps anyone else.
I had downloaded and installed the Perian plug-in. (It installs in the preferences pane in the Mac's system settings.)
In previous versions of OS X, Perian was a sometimes essential to getting 5.1 surround from a Mac. I know I used it with great success in OS X 10.5 and 10.6.
However, I was having real troubles — some of them as I discussed above — with my sound preferences in 10.8.2.
After much mucking around, I stumbled upon the solution.
I removed Perian.
I know have no trouble at all. I use either Handbrake, and more recently iVi Pro, to convert movies for iTunes. With Perian removed, the only change I need to make in some movies is to select the surround sound track. Mac OS X will automatically change the settings if necessary in the MIDI player, and my Marantz NR 1603 does the rest.
If I play music, OS X changes the settings back to stereo, with no intervention.
The only setup that might be necessary for anyone else is to ensure that your MIDI player is set for your HDMI or optical audio (TOSLINK) device to use 48kHz. -
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.

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
Paper_DragonHave 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.
iPhone, iPad, iPod touch: Turning off and on (restarting) and resetting

Should the behavior continue, it may be necessary to restore your iPhone.

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!

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.

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:

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
