No audio output with wireless projector connection

I use EasyMP Network Projection software to connect wirelessly to a projector. Until about two weeks ago (before Yosemite OS came out) the connection stopped streaming sound through the projectors speakers. The video works but the sound only comes out of my laptops speakers (Macbook Air) and I don't see the projectors audio output show up in the sound control panel. I know the projector is not to blame because other people can use the projector and get sound out of it. I'm also getting an error upon opening the EasyMP software that says "You need to restart your computer to enable Audio Output" but restarting the computer makes no difference.
Steps taken to resolve issue:
Uninstalled and reinstalled the EasyMP software
Reset the SMC
Restarted the computer
Repaired file permissions with Disk Utility.

I have outputs 1+2 connected to a pair of Audix powered monitors. I've tested the monitors with other audio sources, and they work. Also, I'm not getting any audio from the headphone jack. This makes me think that I've either got something set incorrectly with the software, or there's something wrong with the mixer.
I also tried running Garageband with the FW-1884 and had the same problem, if that helps.

Mush/Audio Errors with MacMini (2012) connected via Firewire with Motu 828mk3

Hi,
just bought a Mac Mini (actual model) and wanted to connect my Motu 828 mk3 via Firewire for audio recording. BUT, via FW there are audio errors/mush (sounds like electrical mush) in all the audio outputs. Via USB its all o.k. ! The Motu works fine with an 2008 MacBook Pro on Firewire!
Has anyone the same problem with audio interfaces on macs using firewire, especially on the actual Mac mini? Is it a problem of the Mac (Mini) Firewire port?
The Mac Mini has installed the latest Motu drivers and the latest version of OS X Lion. The problem exists in all audio applications (Cubase, AudioDesk, Wavelab, even iTunes).
Thanks for your help/answers and best regards.

The problem stems from the Mac (in my case Mac Mini Server 2011).
Apparently, as I read in various forums looking for Mac and Logic, the new models of Mac Mini (2011) have lowered the voltage Firewire.
I have the same problem with my new Track-16.
I can only work fine with USB connection.
Either we change the computer model, or users of Mac Mini (2011) we can forget a Firewire connection powerful and efficient.
Only remains for me try to connect to an external HD Motu firewire 800 which is connected to the Mac Mini previously. I guess the external HD, to be powered via AC, will have enough voltage to the Motu.
Best regards.

Officejet Pro 8600 won't connect to wireless with Wireless extender connected

I am trying to get an Officejet Pro 8600 to connect to a wireless network, but it will not connect when my wireless network extender is connected. Once I disconnect the extender, it connects fine. Here is the setup. I have a Netgear wireless cable gateway CG3000D with a Amped Wireless Dual Band Router (R20000G) connected to the Netgear via ethernet cable. The Amped router is setup as a wireless extender, the Netgear and Amped share the same SSID. All my other devices work just fine connecting, laptops, cell phones, and IPads. When the Officejet 8600 tries to connect with the Amped connected, it tells me invalid password. Once I disconnect the Amped, the Officejet connects just fine. Any ideas how to get the Officejet to connect to the wireless with the Amped extender connected? Thanks

Are you using the same passkey on the extended network? (It is best to)
If so I would try using different SSIDs. The printer will try to connect to the network with the better signal which might change depending on wireless interference. There is no way to force the printer to connect to one network over another if the SSIDs are the same.
One other possibility. Is the passkey the same for both 2.4 and 5ghz on the Amped Dual Band router? Most routers can be set up to have different passkeys for each band. The printer is a 2.5ghz device and will need that password the same on both the Amped and Netgear routers.
Please let me know your results. Extending networks is becomming more common. Understanding how to work with them will help everyone.

Audio output with aerender

I'm encountering a strange behavior on CC's aerender that becomes different depending on the presence of ae_render_only_node.txt, even if it's not supposed to.
I've made an example project called test.aep, with a custom output module called "QTAudioOn," with "Audio Output On" to have an audio track every time something gets rendered.
test.w_node.mov is when there was ~/Documents/ae_render_only_node.txt, test.wo_node.mov is when there wasn't. In the same configuration, the yielded files came out different.
test.w_node.mov was missing an audio track, that is supposed to be silent track according to the output module configuration.
It seems test.w_node.mov was created using "Audio Output Auto" output option which was newly introduced with CC. The same process was never a problem with CS6. This problem frustrated me since we concatenate videos in order and merge the audio with other audio track programatically using MP4Box and ffmpeg. Missing audio track scrambles the result video in concatenation process.
Is there any way to fix this problem? Maybe I could make silent track using ffmpeg, but it seems too much.
Thanks.
Don.
Edit: test.aep consists of only one red solid object, nothing else.

For those who are interested, here's how to add a silent audio track to rendered video:
$ ffmpeg.exe -f lavfi -i aevalsrc=0,aconvert=s16:stereo -y -i input.mp4 -shortest -c:v copy -c:a aac -b:a 192k -ar 48000 -strict experimental output.mp4

T520 problem with Wireless Network Connection Adaptors

I was in Windows 7 Device Manager's Network Connections trying to fix a minor WIFI problem by uninstalling the drivers and then scanning for hardware changes to reinstall them. I uninstalled a driver that the scan didn't pick up to reinstall, and I didn't write down its name. Now the WIFI does not work at all. I've updated the two drivers left in Network Adapters:
Intel 82579LM Gigabit Network Connection for my ethernet
Intel Centrino Ultimate-N 6300 AGN for my WIFI
Does anyone know the name of the wireless driver I uninstalled? Does the 520 require two wireless network adaptor drivers? Can't seem to find info on it anywhere!
What I've done:
I ran Intel's PROSet/Wireless WiFi Connection Utility diagnostic tools. The hardware test fails saying "Wireles Hardware is not boudn to transport driver". The Driver Test passed saying "Driver is loaded. Netwsw00 Version: 15.4.1.1. The Radio Test failed saying "Failure geting network radio status!". After that the Scant Test, Asociation Test, Authentificaiton Test, Siganl Test and Ping Test all failed.
Installed every 64 bit LAN wireless network adaptor driver I could find in the T520 section of Lenovo's site
Any assistance appreciated. I'm a bit of a noob.
Thanks

Try scan for new devices in Device manager otherwise you likely have to reinstall the package again.

Audio Output with fullsize headphones

I don't know the specs on the audio outputs for the iMac but can it sufficiently support a Sennheiser HD555 or HD595 headphones for full audio potential? I believe those cans have a 120 ohm impedance so I'm unsure if an amp is needed.

Hi, we just plug em" in direct.. You do have Audio MIDI SetUp (Utilities) - in which you can make various input/output selections....L

Help with Video projector connection

I bought a Brookstone HDMI projector to connect to a MacBook Pro and the Belkin adapter. I get perfect video but no audio. Am I missing something?

Does the projector and/or your MBP support audio over HDMI? Some of the slightly older MBP's don't and you would need to run a cable from your audio out port to the projectors audio in.

HP 175nw Problems with Wireless Network Connection - Mac OS X 10.8.3

Please help!
I have an HP 175nw, from one day to the next it decided it was no longer going to connect to the wirless connection.
I run a Mac on 0S X 10.8.3.
I can't find the installation software (the whole software not just the driver) on the web and the CD is worthless b/c this is a Mac.
I installed the printer on my windows laptop and it works fine, it connected to the wireless network using the setting sets on my laptop, it now prints wireless no problem, but not with the Mac.
I have plugged the printer directly into the Mac but the Mac doesn't even seem to recognize it. The printer shows up on my printer list but when I try to print or scan from it the Mac says the printer is offline.
I need this printer/scanner for work desperately, Any ideas would be greatly appreciated.

Need Help: Trouble with Wireless Router Connection on MBP

Hi all. I just bought a MacBook Pro (my first Mac ever) and love, love, love it. However, one glitch is driving me crazy. I do *NOT* have an airport but I connect to my cable modem through my netgear wireless router. When my MacBook Pro goes into sleep mode, I lose the connection to the wireless router. I have to go unplug the router to reboot it for the MBP to see it again. I think it has something to do with how it is assigning the IP address. Has anyone else seen this issue? Know how to solve it? Thanks so much.

How listening audio output with console digidesign 002

i have conncected the fcp5 with the digidesign 002. I have made all the necessary settings, that provide the connection, through audio/video settings/user preferences etc... Though, when i put something to the canvas, i can listen from the speakers, but the channels of didgidesign don't communicate with the audio channels in fcp.2)when i do log and capture from the cam, the logged footage has sound, but i can't listen to it, when the sound is connected via digidesig. It seems that something is wrong but i don't know what. Does anyone knows?

You have to use the Digi-002 in Standalone mode, as a mixer. Press the standalone button and then select 'Yes'.
I connect the optical audio cable from my G5 into the optical audio in the back of the 002. You'll have to read the manual to make faders 7 and 8 'listen' to the optical port rather than the XLR inputs. And then in System preferences on the MAC, the Audio Out would be Optical Digital-Port out.
The only time I use the 002 in it's regular mode is i) when I'm using Pro Tools, or ii) when I'm using Garageband and using the 002 as my audio input device.
Hope that helps.

Audio output with monitor conneted

i ahve a macbook pro and whenever i connect it to my cinema display then hook up to speakers i get this feedback on audio system. if i unplug monitor feedback dissapears. does any1 know a way to solve this?
Message was edited by: mark2kay

Maybe you don't really mean feedback. Are you hearing a very loud squealing? That is acoustic feedback from an open microphone near speakers.
Do you hear soft varying buzzing noises? That seems to be a ground problem with external display and external speakers connected. See this thread:

Help with wireless internet connection

Hi all,
Excuse me if I'm asking a repeated question, as being abit IT challenged, I just don't know where to look for a correct answer.
I've just gotten a new Powerbook G4 that came with the Airport Extreme, and also a wireless router.
Following the instruction that came with the router, I hooked up my ADSL modem to the router, and I tried to configure the wireless network.
As instructed, I was able to log onto the website provided by the router and ran the wizard to start the configuration process.
However, when all these are done, I couldn't log on to anyother website anymore, with Safari telling me that there's no internet connection.
From my desktop, I could see that Airport is on, and could locate the 'Default' network, plus other network within the neighbourhood. My service provider is using PPPoE.
Can anyone enlighten me as to what is wrong with my processes, and how I can rectify the problem?
I don't what other information you need in order to help me, but I'll be glad to provide it if asked.
Thanks guys and girls!
Cheers,

Hi Kenny,
Firstly, make sure your wireless network name is something unique - the name of your first pet, or a random set of letters - so you can be certain you've connected to the right router.
Secondly, are you connecting wirelessly (ie. not with an ethernet cable) to the "web site" of the router? If you are then that means the wireless part is working OK.
If you use the System Preference application and look in your Network Preferences for your Airport connection and under the TCP/IP tab you should have it set to configure IPv4 using "DHCP".
Depending on the router you bought there should be an option in its configuration to turn on DHCP on your network (this is a different option to the one for using DHCP to connect to your ISP) - make sure it is enabled.
With these set up what does the Network Status pane in Network preferences say for your Airport connection?

Audio Output with firewire audio interface issue

Hi, i have a quick question that maybe someone here can answer for me. I originally posted this in the OS X forum but someone recommended that I may get better help here.
I have a PowerPC G5 with Mac OS X 10.4.11. I do a lot of home recording and use a Presonus Firebox Firewire recording box. I recently picked up some new monitor speakers that I run the outputs of my Firebox to and I use the Firebox as my output sound device in my system preferences.
Everything works pretty well unless I touch one of the volume buttons on my keyboard (which I tend to do out of habit pretty often). If I do press one of the buttons the volume dips way down and I have to pump my speakers and firebox volume up all the way up to hear them. If I do this, and then happen to put my computer to sleep when I awake the computer the volume is now at an extremely high level until of course I press one of the volume buttons on the keyboard.
The big problem is I have twice in the first two days of having my new speakers turned them way up and later in the day awoke my computer from sleep mode and had itunes or a dvd BLAST out of my speakers at a ridiculous volume.
My question would be is there some way in os x I can disable the volume buttons from being used if i am using a different output device? OR is there a better way for me to set my system up in my system preferences?
It was suggested in another forum that I look into the help for the Firebox unit instead of the mac so I have started to do this as well. I just thought that because everything works fine UNTIL I touch the computers keyboard it seems like the computer is making some drastic change in how the sound is being output, so I thought I'd try to find an answer here as well!
Thanks so much to anyone in advance who has any sort of help with sound preferences and or settings!!

This is a very good point! Thanks for your response.
I do realize that I have multiple volume controls going on here in a chain. First my computer, then the Firebox interface, then my speakers have volume knobs...
But what I am seeing is when I first press a volume key on my computer (even if it is the VOLUME UP key) there is drastic lowering in volume. Only until I put my computer to sleep, and awaken it does the volume return to a normal level.
It seems that when I am pressing the volume on my computer it is activating something on the mac's end... or changing the way the sound is being output.
Again all of this could be avoided by me not pressing those 3 keys on my keyboard... but old habits die hard! so if there was a way for my mac to give total control of sound output over to my firebox that would be best.
any more help is greatly appreciated!

Premiere CS4 Audio Output with Decklink

Hi,
i found serveral posts in the net for my Problem, but no solution.
Were on a WindowsXP machine with Premiere CS4 and a Blackmagic Decklink Card.
If we choose a Sequence-Preset from Blackmagic Decklink (which is important for us) and choose the internal Soundcard for Audio Playback,
we dont hear anything. The Audio is routed through the Decklink. We have tried everything to achieve that that audio will be played through the internal Soundcard, but it seems as if the Settings are overwritten by the Decklink Preset.
In CS3 this Problem doesnt exist.
Many thankx in advance for your help....
Sascha

oh, we have the actual CS4 Update and Deckling Driver installed.
