X220 no sound from displayport

My X220 does not transit sound to the TV when I connect a DisplayPort-to-HDMI cable with a DisplayPort connector at one end from laptop, and an HDMI connector at the other end from TV. Please help resolve this issue.

You have to use a resolution that is supported by your TV. Don't use windows settings, instead use Intel control panel (or whatever it's called in english). There you can usually see all the resolutions supported by your TV, and if you can't you can change to a custom resolution (just be careful, if you change it into something weird it might harm the display). If it's an HD display you can set it to 1280x720 and it should work.
I've also figured out what's the problem with my connection to the TV. The computer keeps sending a DVI signal even though it's connected through a HDMI cable. I think this is because my TV isn't correctly identified, maybe because it's so old. Ubuntu 11.04 does recognize it though, but it's such a pain to use that i rather just use an extra set of speakers with windows. If I could only get windows to identify it properly everything would work as it's supposed to.
By the way, I also use the latest drivers and have tried older ones aswell but it doesn't make a difference for me.

Supports multi-channel digital audio output on compatible devices
make sure your ipad is not muted
make sure you volume is not all the way down
make sure audio play out of the ipad when not connected to the hdmi adapter
if you did and it don't work then it's likely an issue with the connetor
or the tv or it's settings

Playing sound from my macbook to my imac

I'm using my iMac as an external display for my macbook pro. Since my iMac does not support thurderbolt, I've had to connect it using a Mini displayport. I've bought a 3.5mm Male to Male Stereo Cable so I could play the sound from my macbook through my iMac but both go silent. Anyone have any suggestion on how I could play sound on my macbook through my iMac? Thanks in advance.

Firstn make sure that the male audio cable is plugged into the "audio out" port on the MacBook and is plugged into the "audio in" port on the iMac. Second make sure you are in the MacBook system preferences (Not the iMac) then click headphones. The thing named "Headphones" is your iMac. I hope that helped

Mac mini 2014 won't do 5.1 surround sound from HDMI port

I can't seem to get my Mac mini 2014 to do 5.1 surround sound from the built-in HDMI port to my home theatre system. When I run the Audio MIDI Setup program the only option is 2ch-24bit (stereo). Now I didn't have this issue when I tested it with a Mac mini 2012 running 10.9.5. It allow me to select 6ch-24bit (5.1) and Encoded Digital Audio. I also don't have an issue with the Mac mini 2014 if I use a Belkin Mini DisplayPort to HDMI Adapter connected to one of the Thunderbolt 2 ports. It does 5.1 surround sound just fine. So is there something wrong with the built-in HDMI port on the Mac mini 2014 or OS X 10.10?

No sound from TV when using HDMI from HP Envy Ultrabook4 despite downloading drivers

Problem: When using an HDMI cord from my HP Envy Touchsmart Ultrabook 4 (4-1105dx)to connect to my TV to view movies, the video appears on my TV screen, but there is NO sound from the TV. Instead the sound comes from my lap top.
Troubleshooting: I have looked under Sounds in the Control Panel, but the only choice listed is Speakers & Headphones IDT High Definition (which is the default) and does not allow sound from the TV when using the HDMI. I have also tried to download Driver and Audio Graphics, but wasn't sure which one & the ones which were downloaded have not solved the problem.
Can you assist me? Which is the correct Audio/Graphic Driver to download? Or is there another possible reason why I cannot hear sound from my TV when using the HDMI to connect to my lap top?

Hi,
Please try this first to enable Speakers in Playback devices as follows:
1. Right click speaker icon (bottom right hand corner)
2. Select Playback devices

4. Enable it
5. Click Apply/Ok
Regards.

No output sound from output port/analog audio: Need help

hello, I want to connect my analog audio equipment to my iMac. I have done this in the past with my old G3. I have connected the RCA cables to a 3.5 mm jack and put it into the audio input port, which was what worked on the G3. When I open the sound page for input & output, on Output I can see the volume bar thing moving in relation to the sounds from mic, turntable, etc: all the analog audio things. However, there is no actual output of sound through the iMac;s speakers or a headphone. The output page is pretty simple so I am real sure I have all the rigt things checked, unchecked etc. Any ideas? Thanks.

I had what sounds like a similar problem to jazzzrat. i had my macbook setup to a stereo and it worked for over a year. suddenly no sound came out of the stereo. in my case, it definitely was a software setup thing.
plug in your stereo jack into the audio out port. then go to system preferences-->sound-->output. on there you should see, under "device for sound output": Name=Headphones, port=built-in output. (if you see name=built in speakers, you plugged in the wrong plug). Now go down to the bottom of the window and UNcheck the "mute" box, and make sure the volume slider is midway or more.
For some reason, mac allows you to mute the "headphones" and "built in speakers" selectively. we have no idea how that box got checked, that remains a complete mystery. but when we eventually found -- and unchecked -- the box, our stereo output came back just fine.
i hope this works for you. good luck and have a good new year.

What do I need to get better sound from my Mac mini

The sound from my external speakers is very poor. I am hard of hearing(50% in one ear) and I find it very difficult to follow a conversation etc.
I am now on Yosemite, and the speakers have been used on all my previous pc's successfully. I cannot find a control for the built-in audio, does one exist?

What do you mean by poor sound?
The Sound is controlled by System Preferences>Sounds>Output

No sound from optical output when using hdmi/dvi cable

I am trying to connect my apple tv2 to my B&O Beovision 7. I have used an HDMI to DVI cable which is working fine for the picture; but obviously DVI does not carry sound. I have therefore connected an optical cable to the digital optical output on the apple TV and put this through a converter to digital coax, which then goes in to the TV. I know the optical cable / converter set up works fine as I have tested it on my sky box and it works fine. But I get no sound from the apple TV - any ideas?

I hav exactly the same problem... Did you resolve this??

No sound from the TV when using HDMI cable, No sound from the TV when using HDMI cable

I recently purchased HDMI cable and adaptor, so that I can play downloads from my Macbook Air on my TV. There is only sound from the Macbook, not the TV - Do I need as separate cable for sound?

I've got the same issue: when I connect my Macbook Air (2011) to TV via HDMI cable there's no sound through the TV system, only from the Macbook Air. I used to use my older Macbook Pro with the same HDMI adapter and it worked just fine, but not with the Macbook Air it doesn't.
My software is up to date. I tried to select the TV as an output option in sound preferences, but it doesn't yield any results.
Rebooding multiple times doesn't help either.
Any suggestions on how to tackle this problem?
Thanks in advance.

Recording sound from DVD and CD play

I just bought a Zen V Plus. Could someone please tell me how to record sound from a DVD and/or CD to my MP3? Thank you!

Try this:
1. Connect the Line IN jack on your player to the line output of an external stereo source, such as a CD or MiniDisc player, using the supplied line-in cable.
2. Press the Back/Options .You may need to do this more than once until the main menu appears.
3. Select Extra button to start a line-in encoding.
5. On your external stereo source, start playing the song you want to encode.
6. While encoding, you can press and hold the Back/Options button and select one of the following items:
Pauses the encoding. You can also pause the encoding by pressing the Play/Pause button.
Stops and saves the encoding. You can also stop the encoding by pressing the Record
Split Ends and saves current recording session, and begins a new one.
7. Press the Record button to end the line-in recording. The recorded track is named LINE followed by the date and time of the recordin YYYY-MM-DD HH:MM:SS<. For example, if you record a track on March 5, 2004 at 2:57 pm, the track is named LINE
This information can also be found in your user's guide, it's a .chm file found in your installation cd.

So does this mean that I cannot have rotation lock off and the mute function off at the same time? In other words, can I have my screen rotate automatically as I hold my iPad in either portrait or landscape AND hear sounds from my apps at the same time?

In other words, can I have my screen rotate automatically as I hold my iPad in either portrait or landscape AND hear sounds from my apps at the same time?
Yes, you can. You can configure the Side Switch (above the volume button) either as Mute switch or Rotation lock.
Settings > General > Use Side Switch to: choose what you like the Side Switch to function as.

After upgrading to yosemite my macbook pro late 2011 does a random sound from time to time.

After upgrading to yosemite my macbook pro late 2011 does a random sound from time to time. Its completely random and i already checked all apps in use and its not from them.

Sounds like Notifications app.
Maybe some other app. In SystemPreferences->Users&Groups->LoginItems tab: remove all entries with the minus sign underneath. This will not uninstall anything, you have to start those apps by hand now. Restart.
Still there?
Yes: Restart again while holding the shift key, this will start the mac in SafeMode: only the necessary items are loaded to run.
Still there?
Yes: Make an etrecheck list and post it here.
No: Restart, put the items in the LoginItems back, one by one, restart after each entry, and you will find the "culprit"
Please report accordingly. I will be back in 24 hours.
