Audio cuts out (mDP - HDMI) when entering clamshell mode

Hi - my MBA is late 2012 (8 GB, 2 GHz i7, 10.7.4). When I hook it up to the LED TV (a Toshiba 40L2200U) using a Folsom miniDisplayPort to HDMI cable (no separate adaptors, it's a 6' cable with mDP at one end and hdmi at the other) it works fine - audio is transmitted and it comes through the TV speakers. But when I close the lid and try to continue watching with the laptop in clamshell mode (a magic trackpad is around that is paired to it), video continues just fine but the audio cuts out.
Annoyingly, when I open the lid back up the audio still doesn't work. I have to futz around a while before it comes back (restart any programs with audio output, unplug the cable and plug it back in again, move the audio output in system preferences to core audio and back again to the TV etc.)
Does anyone know what's up with this? I don't think it can be the cable's fault--clearly it's able to transmit audio along with the video, and nothing changes about the cable when I close the lid.
Could anyone with a similar setup (MBA/Lion -> TV via HDMI adaptor) let me know if you are able to enter clamshell mode without losing audio over hdmi?

In 'alsamixer' I have a setting called ''Headphone Jack Sense' which if enabled mutes the speaker when a headphone jack is inserted.
What's the output of
amixer get 'Headphone Jack Sense'

Audio cuts out over hdmi

My current setup is a 2010 mac mini running OS X 10.7 with audio and video going through a HDMI cable to a onkyo receiver which then passes sound to my home theater speakers and HD TV. Every now and then, the audio will cut out for about 4-5 seconds but the video will be fine. When the audio cuts out, the status display on the receiver will show "no signal". This never happened when it was running OS X 10.6. Has anyone else experienced this problem? Any suggestions for a fix would be greatly appreciated.

Hello dmurfett,
Welcome to the HP Forums!
I see you have some issue with sound cutting out at higher levels. Can you please confirm if this is happening with the notebook speakers and headphones, or if it's only one of them.
Just to make sure the correct driver is installed and not the Windows driver, uninstall the audio drivers and reinstall using one of these downloads:
Windows 7 64-bit - IDT High Definition (HD) Audio Driver
Windows 8 64-bit - IDT Audio Driver
You can also try this:
1. Open Control Panel and click Hardware and Sound.
2. Click Sound.
3. While on the Playback tab double click on Speakers to open the Properties window.
4. Go to the Advanced tab and click the Default Quality drop-down.
5. Select the highest quality output (the highest Hz setting), and click Apply.
6. Click OK, and test this setting.
If this doesn't work, try the following:
1. Open Control Panel and click Hardware and Sound.
2. Click Sound.
3. Click on the Recording tab, and double click Stereo Mix to open the Properties window.
4. Go to the Advanced tab and click the Default Quality drop-down.
5. Select the highest quality output (the highest Hz setting), and click Apply.
6. Click OK, and test this setting.

Why is my audio cutting out in iMovie when I do green screen?

I am creating a newscast in iMovie using green screen. As I get farther into the movie, the audio cuts out of the scene. Why is this happening?

The audio from both background and green screen foreground clips should play simultaneously but you should be able to adjust the tracks individually.

Apple TV audio cuts out when its the output device

Guys,
I have a 2011 iMac and select AppleTV in my output devices, play some tunes from iTunes or Spotify, and it will play for a while but it will eventually start cutting out and eventually drop completely. Instead of rebooting, I have to run the command
sudo kill `ps -ax | grep 'coreaudiod' | grep 'sbin' |awk '{print $1}'`
to restart the core audio service.
Is this an AppleTV issue or a router issue? My AppleTV is plugged into my Asus router via ethernet. My iMac uses wireless as well as my iPhone and iPad. The issue is still present when using airplay with my wireless devices. The audio will start sounding glitch-y, then completely cut out. Annoying when trying to enjoy music on the porch.
Appreciate any input!

Also, I had never seen iTunes show this orange status color in iTunes...

Midi Audio Cuts out when Playback tracks are triggered.

Hi,
I am having an issue where if I open Mainstage 2 and begin playing a Midi Sequence through a 3rd party Plug-in, the audio cuts out from the plug-in when I trigger my group of Playback tracks for the first time and only restarts when a new note is played. This is particularly a problem because the sound is arpegiated and continuous. 9 out of 10 times if I do it again right afterwards it will be fine without any issues at all. There was a time during rehearsal when it absolutely would not work, but I think a restart fixed it. CPU usage and memory usage do not seem to be the problem.
So my question is, is it normal for it to do that on the first time? Is there any reason why it would not absolutely work that time during rehearsal. And lastly, is there anyway to make it just work every time!
I have tried reading up on this, and from what I understand, putting each playback track on a separate patch might help. My issue with that is I have already designed a layout that fits everything on one screen in one patch. I don't want to be switching screens during a song to adjust levels for the playback tracks. I have One Vocal, One Midi Synth, 8 playback tracks, and 3 Aux strips.
I am new to mainstage and might not completely understand how to make a set work with patches, but from what I understand if I put the playback tracks on different patches I can't control everything from one screen.
Any thoughts, insights, or advice is greatly appreciated.

Logic has that issue at times as well- where the first notes of a midi passage may not play. I believe the timing is such that the note starts are actually slightly before the first beat. Check your starting notes to make sure that they are really starting on the first beat and not slightly before.

Audio cutting out when using D2 external Firewire Drive

Hi,
I have just upgraded to Logic Studio, using the following setup:
Macbook Pro
Motu 828
AMT 8
Logic Studio
D2 Lacie 500GB Firewire Drive
As the MacBook's internal hard drive is not sufficient to record and playpack efficiently, I was advised to get an external Firewire Drive. Given that I have very little space on my laptop - (am running windows on a partition also) I am trying to save my logic files to the external HD. When creating tracks specifically using Audio Instruments, the playpack keeps cutting out.
I am connecting the HD via usb 2. I am also having to freeze the tracks in order to record more layers. There is lots of clipping and latency. I thought by using the external, this problem would be resolved.
The HD is not playing back the tracks fast enough, and keeps cutting the audio out. The audio cuts out everytime the blue light on the drive flashes.
I cannot save the files to the MackBook HD as there is notenough space.
Is there something very wrong with my setup?
any advice would be really appreciated.
ps. I am a bit of a newbie
thank you in advance.

Connect it via firewire 800. USB2 is not good for audio or video streaming.
I have 3 D2's connected to my mac pro, works like a charm.
good luck.

Audio cuts out at slide transitions when played on TV

The audio on the DVD is my own narration, nothing downloaded from iTunes--and it works fine both in the iDVD viewer and DVD player on my computer. But in the DVD player attached to my TV, the audio cuts out at each slide transition, which are dissolves.
The image files are relatively small, and there are only 25 slides. I burned the DVD at 4x rather than maximum speed to enhance quality. In preferences, I have "best quality" rather than "best performance" checked for the encoder settings.
Please let me know if you have any ideas for a fix.

Is the audio embedded in the video or did you do a voice over?
If it is embedded in the video, you might try extracting the video and then adding the transitions.

My streaming video audio will cut out for several seconds at a time then return to normal again. I can, when the audio cuts out, turn up the manual volume on my surround sound to hear however when audio returns, I get blasted until I turn down the surround sound again. High CPU utilization *may* be a contributor to this problem - currently averaging about 95%.
What can I do to correct this problem?

Hi MDS,
Here are the possible HP products for a Touchsmart 9100. Both models do not list Win 7 Home Premium as an HP supported operating system. Did you upgrade from Vista to Win 7 or did you perform a clean install of Win 7 Home Premium?
Both models also reflect this updated driver version (6.0.1.5932) for Realtek High Def Audio. You have driver version (6.0.1.7076) installed on your PC.
You could try installing the version per the above link if you have Win 7 Pro 32 bit or 64 bit installed.
Try checking your file system by opening an administrative command prompt and entering the following: sfc /scannow
You may have to schedule this task to run at the next boot. Please reboot your system to run the task.
Do you know which process is consuming all of your PC's CPU time?

Sony STR-DN1040 audio cuts out briefly, frequently

Audio on my new Sony STR-DN1040 cuts out whan SAT/CATV is the source. This happens frequently (every 30 seconds to a minute, unpredictably), though it is only for a fraction of a second each time.
When the audio cuts out, the following items on the front display panel of the receiver all flash off momentarily:
A.P.M.Dolby Digital SymbolD.L.L.
When I reconnect the cable box directly to the TV instead of the receiver (same HDMI cable), the audio issue goes away. I have tried resetting/clearing the receiver. Any thoughts/suggestions?

Thanks again for your suggestions! They are much appreciated.
I have noticed that the problem is apparent on some TV channels more than others. Some channels seem to cause the audio drop and other channels don't.
I have now tried attaching my Blu-Ray player to the SAT/CATV port using the same HDMI cable. The problem was not apparent (but I haven't noticed the issue with the Blu-Ray source previously, so perhaps that helps rule out the SAT/CATV port).
I also tried attaching the cable box/PVR to the BD port and the problem was still present (as mentioned earlier, mostly present on certain channels).
The software is up to date as of last week (ver. s9327.1074.0).
I also tried powering off and disconnecting everything, then reconnecting and powering everything on in the described order. The issue is still present, regardless of the HDMI input port that I use. As mentioned before, this happens only when I route the SAT/CATV signal through the receiver. When I bypass the receiver, by connecting the cable box/PVR directly to the TV, the audio does not cut out on the usual affected channels.

Audio cuts out at times for a few seconds with VOD

While watching VOD the audio will cut out at times when the program is playing. I have reset the boxes, and router with no change. I have read on a post that someone had pixilation issues and the Verizon techs hooked up a cat5e from the ONT directly into the router, which solved her issues. Is this something I can do, and will it help my issues?
Thanks, Charlie

Today I tried to find the answer to my question, again... And tot my surprise I found it!! When I played music with winamp I saw in the systemtray that the Creative volumecontrol actually did mute the sound automatically for a few seconds. The reason for this I don't know. In de surround mixer I clicked standard. Music is playing ok now., no more interupptions. Seems to me something is wrong with the Creative software.....

Audio cuts out for a few seconds

Hi,
I'm not sure if anyone is experiencing this but it happens to me all the time and it's so so annoying.
When playingback the timeline on CS6 the audio cuts out at random places and then it comes back, then it goes again for a few seconds then back again,..while video keeps on playing.....this is just random and it can happen as soon as you press play or after a few seconds and it happens when audio is stereo, mono, mp3,wav,aif, you name it.
Also, it happens regardless of playback quality or timeline render status (red, yellow or green). My computer is quite fast + 24gb RAM so I dont think the PC is a problem, It also happens on a different computer within our studio.
Needless to say that editing under these circumstances is becoming impossible/frustrating and I'm even considering finding other software to edit with! I've found others with this same problem at cretive cow http://forums.creativecow.net/thread/3/935424
If anyone from Adobe reads this, please help!!!
thanks in advance

Unfortunately there's no fix for this problem that plagues Classic since release. Considering that a new generation appeared I guess we have no reason to expect a fix anymore.
I also have the problem and it makes the iPod Classic less desirable to be used as a music player than a generic $10 (no name) usb stick.

Audio cut out and midi miss sync

Lately I have been getting audio cut out, and the missing, 'error while trying to sync audio and midi'.
I thought it was that I had too many instances of virtual instruments. So I mixed the song down. Imported that into a NEW song, with only one audio track, and then proceeded to try to do an organ overdub...Well Logic still drops out and gives me the message, even though there is NO midi information in this file...
Then I noticed that even AIF or mp3 files, didn't play properly from the desktop preview mode. They stop too. Activity monitor doesn't seem to be showing anything overworking..
Disk Warrior fixed some volume errors,
Anyone have any ideas to try?

I'm using a motu828. I disconnected the firewire connection, and ran audio from the headphone jack to the motu, and VOILA, no problems... Last year, I went thru two motu units, not really sure if they are the issue.
I think it might be LOGIC's firewire circuitry. Apple techs couldn't find the issue, I had the G5 motherboard replaced. Another factor was I had 3 Lacie firewire drives (2 firewire 800, 1 400) I have had 4 Lacie drives die on me in the last 3 years. They are the only firewire drives I have, so I don't know if the fault lies with them, or the again Apples firewire circuitry, stressing the drives out???
I also put a firewire 800 card in my system.
I have now switched to an external ESATA raid setup. No more firewire drives. So far so good. Since I had the whole motherboard replaced, I don't know what that means in terms of MOTU connected via firewire..
For now, I'm running audio out of headphone jack, using all virtual instruments, so I know it will sound better when I get firewire audio up and running, but I got tired of it cutting out every 3 - 30 minutes. I'm thinking about the apogee duet unit. But again if it's connected via firewire, I don't know where that leaves me..
My G5 is three and half years old, perhaps it's tired and wants to be retired....
The dark part of me wonders, if Apple computers don't start crapping out after three years of heavy use, or is it that technology, software, updates, push the hardware beyond it's capacity after a few years.

After recent upgrade to Yosemite on Macbook air bluetooth audio cuts out and associated video stops with audio. Likewise with airplay and Apple TV. I have deleted all my saved wifi connections and restarted numerous times. I do not expect a resolutio

After recent upgrade to Yosemite on Macbook air bluetooth audio cuts out and associated video stops with audio. Likewise with airplay and Apple TV. I have deleted all my saved wifi connections and restarted numerous times. I do not expect a resolution from the community, but hope to get the attention of Apple engineers. If you are having same problems or have a miracle cure I am all ears.

May start my own thread, but I'm having similar issues.
I've been using an old iMac (running 10.7.5) and Apple TV for years with no issues. Last week I bought a new Macbook Pro running Yosemite and have had audio issues multiple times. The weird thing is that sometimes it works flawlessly, other times (like now) I spend half an hour just trying to get a song to play.
My issues are: When I got to "computers" in Apple TV to stream my music, my music is sometimes chopper or intermittent, and I seen to know when it's going to happen based on the status wheel just before it plays. When I choose a song, the status wheel will spin for an unusually long time, usually an indicator that the audio is either not going to work, or stutter.
When it does finally pull up a song, the playhead sits at the beginning of the song for a good 3-5 seconds before actually playing. Then, when it starts playing, it's all downhill. It will play a few seconds, drop out, play a few more seconds, drop out, and then ultimately the playhead will keep moving across the song as if it's playing, but there's no audio.
Again, this is a new phenomenon never experienced by me. I've tried everything I could think of, some of them all at once:
• restart Apple TV
• restart Macbook Pro
• quite iTunes/open
• turn off Home Sharing on iTunes then reconnect it
• unplugging and cycling both my modem and router
None of these have alleviated the problem.
The odd thing is, like this morning, the audio started up perfectly and never gave me any issues. It wasn't until later in the day that it started. Perhaps after the macbook pro had been put to sleep? Not sure.
Regardless, this is an annoying trait, one that's new to me and my system (as stated, worked flawlessly until my new purchase), and is 100% limited to either a) the macbook pro b) Yosemite or c) both of them.

Why does my facetime audio cut out?

When I am facetiming with mac laptops running snow leapord after a period of time, the audio cuts out.
What causes this and how to prevent it? It is very annoying.
They can hear me but the audio from them is mute.

If the iPod plays fine after you start the car, then most likely its fine and normal. If it doesn't, try contacting your dealer.

Audio cuts out most of the way through an iDVD image

We created a Quicktime file using Final Cut Express HD 3.5, and imported the Quicktime fill into iDVD 6 (all patches have been applied to iDVD and to Quicktime, and Quicktime has been upgraded to Pro version). The iDVD preview shows that all audio is present all the way through the end of the video(about 1 hour and 5 minutes), which means that the Quicktime file has all the audio present.
However, after creating a DVD disk image with iDVD 6, the audio cuts out completely about 55 minutes into the video. The spot where the audio cuts out is not near any chapter marker nor near any transition of any kind in the Final Cut editor session.
By the way, I am creating the image on an external Firewire drive with 112 Gbyte free, although we also tried the internal hard drive which has about 20Gbyte free.
How can I figure out how to get all the audio onto the image created by iDVD?

I believe I've found the cause of the problem! Within Final Cut Express, I found a system setting for output buffer size, set by default to 2Gbyte. I also found that the default 'Convert to Quicktime' setting is for Internet Fast Start. I increased the buffer size from 2Gbyte to 3Gbyte and unchecked Internet Fast Start, and I have no more audio drop out!
I think that iDVD has a bug when multiple file segments are linked together in the Quicktime file (because of the smaller FCE output buffer size). Note that the iDVD preview did not experience the problem, so that part of the iDVD app seems to handle multiple file segments correctly, whereas the part that processes the file segments while creating the DVD image seems to have the bug. Increasing the buffer size masked the iDVD bug.
So if anybody from Apple is listening, please fix your iDVD bug please!
Concerning the ZR85, I do re-use tapes quite a lot and have never experienced problems. I do clean the ZR85 heads periodically. However, I shall consider using new tapes more often.
