I need help getting sound to come out of my TV when using HDMI. Any solutions?

I'm able to pull up my picture when connecting my HDMI cable to my Macbook pro...however I can't get the sound to come out of my Toshiba TV.  When I go under system preferences, then sound and select my Toshiba TV as an option.  It says it has no output controls.  I fiddled with my sound setting in my TV and stil no luck.   Does anyone know any solutions for this problem.  Help is greatly appreciated.

Hey jbarwins
Check to make sure that you are up to date on your computer. Another recommendation would be to try a different cable and also reset the NVRAM on your computer.

  • I can't get sound to come out of my TV when hooked up to my computer?

    Hi there- I have been trying to watch movies from my computer on my TV (a Samsung), but I'm having problems getting any sound. I am currently running on OS X 10.5.8 on a 2008 Macbook. I originially tried using an HDMI cord and have had no problems getting an image onto my TV, but I wasn't getting any sound and was told the cord was for both audio and visual capabilities. So my next attempt to get sound was to use an RCA to auxillery adapter to my computer, but I'm still not getting any sound. When I go into my sound preferences and see if I can change the output to the TV, my only option availiable is the internal speakers on my computer.
    I'm thinking that because I have both the HDMI and aux plugged in, my TV is only trying to read the HDMI cord and not recognizing the RCA input, but I could be completely off. Am I missing something? Thanks in advance for your help!

    As far as I know, 2008 Macbooks do not send audio over HDMI. HDMI on these models are Video only.
    Also, many TVs do not accept RCA input when there is a HDMI video signal. Some TV's have options to use HDMI and an alternate audio input at the same time. My Philips TV can accept HDMI video and a separate audio in at the same time via a headphone-jack type input. However my TV cannot mix any RCA input with HDMI.
    I have sucessfully used my 2006 Macbook on my HDTV using HDMI for video and headphone-jack-input for audio, so it is definitely possible. You just need your TV to play nice.

  • Why does sound only come out of 1 speaker when I dock my iPod?

    My son's Ipod only plays sound out of I speaker. When I dock the ipod on his ihome radio or my sony radio, sound only comes out of the left speaker. When I put other ipods on the same docks i get sound out of both speakers. It is just this one ipod that won't produce sound out of both speakers, no matter what docking station I use.

    Likely it is a hardware issue for the iPod, you need to bring it for service

  • IdeaTab s6000 F - Sound only comes from the left side when using headphones

    I have tried four different headphones including a set of Beats and the sound only comes out of the left side. It just started doing this three-four days ago. I have tried resetting the tablet back to factory but it did not work. Is there any way to get this to work? I would hate to have to return it as I love the tablet besides this one issue. 

    Hi Cory74,
    Welcome to Lenovo Community Forums!
    I’m sorry to hear that Audio is not working as expected from right side in your S6000-F Tablet even after performing the Factory reset, as the issue persists this seems to be hardware related. I would Strongly Suggest Calling Technical Support for Assistance to get the details of nearest Authorized Service Center to get the issue analyzed.

  • Can't get sound to come out of speakers; new to Logic

    Just installed Logic Studio on my new Mac tower intel machine. Have Bose companion speakers plugged into Mac. iTunes etc comes out just fine, but nothing from Logic; Logic comes from the towers tiny internal speaker.
    Help?

    Go to the audio hardware preferences, and select which audio interface you want Logic to use.
    I strongly recommend getting started with the Getting Started manual, which walks you through all the basic setup stuff.

  • My iPad print-outs only come out on 1/4 of page. Any solutions?

    MY iPad print outs on appear on 1/4 of page. Any solutions?

    For a printer that lacks sensors the Photo app will print 4x6" photos. Maybe that is what you are seeing.
    Higher end printers that have sensors will print the photo on the paper size that is loaded.
    You can either load 4x6" paper in to your Deskjet 3070A or you can print from another app that offers more control over the output size. I sometimes place a photo in to Pages and resize it there. You can also try the HP eprint Home & Biz app.

  • Need help macbook won't come out of sleep mode

    Please help I have had my macbook since may of 2006 and this is my first real problem with it.
    I basically been loading videos to watch and then downloading some of the videos,once the process had been started I would leave to allow the videos to load/download but when I come back I find the macbook in a state of sleep and the only way that I can think of to getit out of this is to shut it down and reboot.
    This is my first mac and up until now I was quite impressed so please help to not soil the good Apple name.
    13" Macbook   Mac OS X (10.4.10)  

    I'm a newbie so I might not answer your question, but if you leave the macbook open and it goes to sleep, then you just have to press the power button and it should turn back on. I always thought though that if you let it sleep, then you won't be able to download anything because the computer disconnects from the internet during sleep. Am I right? Lol, now I'm asking the questions.

  • Need help getting an area code out of my program.

    I wrote a program that displays a phone number with a bunch of things, like mutators, constructors and what not. Then I created a test class to test the methods. It prints the phone number, but it won't extract the area code from the number. Any advice on what I'm doing wrong?
    Here's my test class
    public class PhoneNumberTest {
        public static void main(String[] args)
            PhoneNumber number=new PhoneNumber();
            PhoneNumber code=new PhoneNumber();
            number.setNum("612-219-9042");
            System.out.println("Phone Number: "+ number);
            System.out.println("Area Code: "+ code);
    }Here's my class i'm testing
    public class PhoneNumber {
        private String wholeNum;
        private String areaCode;
        public PhoneNumber(){
            wholeNum="";
            areaCode="";
        public PhoneNumber(String num, String code){
            setPhone(code, num);
        public String toString(){
            return(areaCode+" "+wholeNum);
        public String equals(){
            return(areaCode);
        public void setPhone(String num, String code){
            wholeNum=num;
            areaCode=code;
        public PhoneNumber setAreaCode(String code){
            areaCode=code;
            return this;
        public void setNum(String num){
            wholeNum=num;
        public void setCode(String code){
            areaCode=code;
            code=wholeNum.substring(0, 2);
        public String getWholeNum(){
            return wholeNum;
        public String getAreaCode(){
            return areaCode;
    }

    Okay. Well sorry about the post. I'll try to fix it all then.For starters, look at this "test" code:
    PhoneNumber number=new PhoneNumber();
    PhoneNumber code=new PhoneNumber();Do you really need two PhoneNumber objects to hold one phone number?

  • How to use iphone as a microphone for the sound to come out in a bluetooth wireless speaker? what app?

    well i want to do the impossible- i think. i want to know if i there is an app that will allow me to use my iphone as a microphone, for the iphone to be able to be connected to a wireless bluetooth speaker, and for the sound, to come out on the speaker. (the voice) without any cables. in order to do some fun stuff like karaoke or just talk.

    Hi redzknzz,
    I see this has been up for over a year with no responses. Did you ever find a solution? I'm interested in something similar. The apps I've seen require the iPhone be connected to a powered speaker with a stereo cable. There are apps that allow you to connect to another iDevice via WiFi, which can then connect to the speaker. No output via Bluetooth yet.
    Have you found anything?

  • How do I get the sound to come out of external speakers?

    How do I get the sound to come out of external speakers?

    Thanks for our reply.  My speakers are powered Bose speakers but still didn't pick up the sound until I tried this suggestion from another discussion thread.  This worked like a charm:
    Re: External speakers don't work created by ally100 in MacBook Pro -View the full discussion
    I had a similar problem a while back. The issue was with the speaker jack plug and the macbook phone socket. For some reason the jack plug was not a good a fit, as say the jack that comes with the iphone ear phones. A few tiwsts and turns of the speaker jack plug and it eventually became a snug(ish) fit. Have a look on you tune. There are a couple of videos on there that might help if this is not the issue.

  • TS2634 I bought a ipad back in December and the ear buds never worked.  The sound doesnt come out of what you put in your ear but comes out of the little hole on the outside of the ear buds.  Is this supposed to be this way?

    The earbuds that came with my ipad have never worked.  They have sound that comes out of the outside hole of the earbuds.  When you put them in your ears no sound can be heard.  Has this been a problem or did mine just come broken?

    I have the same problem and it has just started in the last day or so...
    Got the phone late July and then in the last day, everytime I plug into PC or take a photo,  I get the same "Disk Error / Retry message"
    What is interesting is that I always had the Photo Storage location as the Memory Card (detachable).   Seems odd that sometime in the last month or so the phone decided to change my setting to the Mass Memory. Might have been an firmware update that I have done in the past but not sure.
    Changing the Photo Storage Location back to the Memory Card has stopped the error coming up everytime a Photo wastaken, but the message continues when I plug in the phone to the PC.
    Phone was just updated to latest firmware this morning and that has not helped, although during the back-up process I could not save some files from the Mass Memory.
    I wonder if Optus will shout a new phone because their technicians are useless with past experiences and to be honest the N97 really promises so much but offers very little compared to all of my last Nokia's.
