MAC - TV audio connection

I have my mac connected to my tv to use as multimedia center.
Video connection is fine and the audio jack goes into the receiver.
But i came across some weird digital noise coming out of my speakers. It dissapears when i move the mouse.
Question: Is there another audio connection possible than with the audio jack output? Is audio possible through HDMI cable connection?
What is the proper way?
Thanks

Are you using a cable like to get the optical audio out of the Mini:

If you go to Sysem Preferences>Sound>Output is the optical out out selected?

Is there a way to connect the Apple TV as a second display without it automatically changing my Mac's audio output?

Is there a way to connect the Apple TV as a second display without it automatically changing my Mac's audio output? I would prefer to use an audio interface for playback and the apple tv as a third display. I know I can go back to system preferences and swap my output back manually, but it is getting to be really inconvienient. Thoughts?

"Choppy" audio connection

Howdy folks,
I've read the FAQs and the various other threads in this forum and I haven't been able to solve this problem of mine on my own. I apologise if I have missed something!
My girlfriend and I are trying to use an audio connection in iChat. Connecting to one another is not a problem, and the audio is typically crystal-clear and uninterrupted *at first*. Soon, however, it will cut out on my side (her side is more or less fine). Sometimes very briefly, sometimes for a second or two. Often it will happen once and be fine for ten seconds or so (never much longer than that, though); other times it will happen in rapid succession. The net effect is that it is difficult to carry a conversation with these interruptions. I'm hoping, however, that there is something I can do. Any ideas?
We are both running the version of iChat that came with Tiger. We also both have PowerBook G4s. My inet connection is to a university network via ethernet. My download and upload rates are, respectively: approximately 200 KB/sec and app. 45 KB/sec. My girlfriends inet connection is wireless with a download rate of app. 320 KB/sec and upload rate of app. 125 KB/sec.
Thanks for your help!

Hello, Charles
My hightest recommendation: You should upgrade to 10.4.2. It corrects several issues (including iChat AV issues) that were problems in the previous versions of Tiger.
Try this and any other relevant suggestions from Help for iChat AV 3 Problems.
The testing and tutorial suggestions in Using iSight with iChat AV might also give you some trouble shooting ideas if you are still having difficulty after implementing the above suggestions.
Also, being at a university, you might try at different times of day to see whether busy network traffic is causing problems for you at certain times.
If necessary, you can even take your PowerBook to an off-campus network to help determine whether the problem is in your Mac no matter which network you use to connect.

New Mac mini audio problem - beeping from audio output

Hi Apple fans
Please help me. I recently purchased a new Mac mini from my local store. It's three-and-a-half weeks old as of today.
It's an i5 2.3 with 8 GB of corsair RAM.
I like to watch movies and TV on it and have the audio connected to an external amp and speakers via the headphone output.
After a reboot today I lost the sound through that output. All that I hear through it now is an electronic beeping, six notes, descending in pitch, repeating.
I have no idea what it is, other than annoying since this happened on a brand new computer. Not looking forward to the idea of losing my mini for a week as Apple figure it out, but it may be all that's left to do.
Maybe somebody here can help me out - anyone have an idea what's going on? I did an fsck -fy already, and there seems to be nothing wrong, based on that check. For completeness sake, I ran the sound over a USB sound card, and the beeping noise was not there, and sound worked fine. Ditto for the internal speaker - no weird noise there, this seems limited to the headphone out port. I've tried different cables, and even amps, and a set of small speakers without amp. The noise is there when using the headphone jack, and it's absent when using the wee internal speaker or USB-based sound. Please help?
I captured the sound on a video which I've uploaded. It's kind of jarring, so keep your hand on the volume button.

Hi Pascal,
Certainly strange, but I have no ideas other than having it looked at by Apple.

Using iPod Touch to hear mac's audio

Hi,
I would like to watch movies on my mac and listen to the mac's audio via my ipod headphones. I have tried Airfoil, but it lags by a second when I use their player, so I'm looking for something else. I have mac pro with bluetooth, and so does the ipod, is there any way to use my ipod as bluetooth headphones?
Thanks,
Zevie

Bluetooth in the iPod touch is only for connecting to Bluetooth Stereo headphones. It can't connect to a Mac.
To be honest, I think you'll always get a bit of audio lag trying to stream audio over Bluetooth or Wifi to the iPod touch and then ot through headphones (even if its possible).
At the risk of asking a silly question, why can't you just connect your iPod headphones to the headphone port on your Mac (with an extension cable if its too far away), or get some Bluetooth headphones to connect to your Mac?

My mac mini loses connection with my receiver after turning off the receiver then back on

My Mac Mini loses connection with my Onkyo receiver NR-609 after turning off the receiver then back on. The only way to reistablish the connection is to unplug then replug the HDMI cable to the Mac Mini. There's no effect if I unplug then replug the HDMI to the receiver. Any help or suggestions would be appreciated. I've searched a lot but haven't found much of anything so if this is covered elsewhere I would greatly appreciate a link.
Thanks in advance

Hi and thanks. I don't know about the audio prefs. When it happens I am not able to see or hear anything from the computer until I un/re-plug the HDMI to the Mini. I'm not sure it's changing to something else because there's nothing else connected for it to change to. I could see that perhaps the audio will change to the Mac Mini's internal speaker.
I found out last night that if, after I lose the signal, I use my ipad to play a video on the Mac Mini using the Remote app and home sharing the signal gets righted and I can see/hear the computer again. It's quite an inconvenient fix though and I wish and hope someone here can help me.

How do i use my iMac and the macs wired internet connection to share the internet with my iPod and iPhone

How do i use my iMac and the macs wired internet connection to share the internet with my iPod and iPhone. For 6months I had set up a network that shared the internet through bluetooth to my iPod 5th gen but i messed it up when i tried to add my iPhone 5s and i can't remember how to do it.

The following has instructions: OS X Mavericks: Share your Internet connection

Ever since i forgot my apple id password and changed to a new one, I am continually being asked to enter my iCloud password. It then says that this mac can't connect to iCloud because of a problem with "my username". nothing I do in in preferences helps.

You have to sign out completely in System Preference>iCloud (click 'Sign out') on a Mac, or Settings>iCloud on an iOS device (click 'Delete account' - this will not delete the account from the server). Then sign in with the new password.
Your iCloud data will disappear from your Mac or device when you sign out but will reappear when you sign back in.

I intend to purchase a Mac Mini and connect to a regular (not smart) flat screen TV and use such as monitor. Can this setup also allow access to Netflix or Apple movies or an Apple TV is also required?

I intend to purchase a Mac Mini and connect to a regular (not Smart) flat screen TV that will be as such a large monitor. With this setup do I require an additional Apple TV to watch programs from Netflix, Apple Store movies, Y-tube etc?

You can view NetFlix and YouTube via their websites on a Mac computer. You can purchase/play iTunes movies and other thing via iTunes on the Mac.

Bad audio connection

I have a 1st gen ipod shuffle, and it seems that the audio connection is bad. My left ear bud is not working. I even tried different earbuds. if I push the audio connection to one side, I can hear audio on the left side. How can I fix this? I looked all over the discussions and could not find anything on this. I also googled this problem, and it looks like I can order a broken one on ebay and replace the part? Any other Ideas??
This is no longer under warranty.
Thanks!!

See my response to your other post.

Does Apple TV and Optical Audio Connection work?

I've read several posts regarding this issue and I'm a little confused. Does the Optical Audio work on the Apple TV (generation 3), because I haven't been able get it to work. I get sound but no stereo/surround sound. Yet, using the same connection out of my Receiver for my PS3 I do get stero/surround sound. Have I missed a setting on the Apple TV?

Is there away I can check the Apple TV Optical Audio connection to see if it's working? The physical connection seems to be fine. Since the connection to A/V Reciever works, as confirmed by my PS3, I can only assume the Apple TV Optical Audio connection is faulty. Other ideas on how I might validate if the Apple TV Optical Audio connection is truly "broken."

Jack-audio-connection-kit doesn't start

Hi,
I need jack-audio-connection-kit Daemon running for use in some other programs, but it seems it dies immediately after starting. See:
[ja@kamahl ~]$ sudo /etc/rc.d/jack-audio-connection-kit start
:: Starting Jack-audio-connection-kit Daemon [DONE]
[ja@kamahl ~]$ ps -e|grep jack
<no output>
I know this is a bit dumb question, but I really have no clue where the problem could be. Do you?

hello,
i'm having the same problem, i can flawlessly run jackd either via CLI and qjackctl, test sound with mplayer, etc.
However, i can't seem to find a solution that let's me do all this as a normal user:

SG200-08 Loosing MAC addresses of connected devices

I have a SG200-08 Switch that has in the last month been acting up with certain types of traffic. On June 7, 2013 I installed the 1.0.6.2 firmware upgrading from 1.0.5.1. Updating the firmware has not helped.
Last week Tuesday a server that was connected to that switch disappeared from the network, looking at the trouble I had to reboot the server and traffic began to flow. After rebooting the server I found only 1 of 2 MAC addresses from the 1 NIC showing up on the port.
Today I have a Xerox Workcenter connected to the switch on another port and while working on changing settings on the device I stopping being able to reach the device, could not even ping it. I went into the switch port showed active, but no MAC address found in the dynamic table for that port. After rebooting the switch I could reach the Xerox again.
I rebooted the switch on Friday near the end of the day and it was doing better till this morning, all MAC addresses for connected devices were showing up OK. Is the device defective? It had been working OK previously, it is connected to another switch on port 1, and that shows a proper table of dynamic MAC addresses. In both cases of loosing a device it was being used not dormant or in any kind of low power mode.

Dear Michael,
Thank you for reaching Small Business Support Community.
Based on the symptoms; SG200 working fine before, it seems to work ok after reboot, and latest firmware already installed. It seems to me like a hardware failure but still, in order to confirm, it would be a good idea to restore to factory conditions and configure it manually again. Just in case that does not help I suggest you to contact the Small Business Support Center for further assistance;
https://www.cisco.com/en/US/support/tsd_cisco_small_business_support_center_contacts.html
Please let me know if there is anything I can assist you with in the meantime.
Kind regards,

Best audio connection

Best audio connection ?
a) itunes computer via RCA stereo connection to home theatre
b Itunes computer streamed to Apple TV , Apple TV connected via optical cable to home theater
c) this I have not tried ... Itune computer connected directly via HDMi to home theater
Also does the sound-card in the computer make a difference ?
Antoine

I have Fredereih ataxia so my only hobby left is musique and no way I have the dexterity to insert a cd in a tray, I have 400 cd's all ripped at 196kb.
I love my Ipad with Itunes and the remote app to take control of my 5 computers in the house.
My apple tv is ok but I do not have a good internet connection.
In the room where I listen the most music, I have a small EEE laptop.
it is directly connected on a 925 pioneer receiver with 9 speakers (RCA)
Also in this room I have the apple TV connected via the Digital audio cable
Recently (I'm in Canada ) I have been using RDIO (Like Pandora) , they claim sending in 256 kb.
I now notice that here is a difference in Quality for the same file sent it different ways.
played directly from the Pc is not as good as if I use Airplay ?
a) should I resample my 400 cd's at 320kb ?
b) should I buy another Laptop with a good soundcard and a HDMI output.
I would appreciate any recommandation for any laptop under 1000$ ( Only Itune will be o n it.
Regards
Antoine
