Sound only works from one port

My sound only works when I use the output port on the back of my computer, but I'd also like to use the one at the front of my computer for convenience. What setting am I supposed to change to do this? Here is some information about my system.

My guess is that I want to use device 2 of card 0, so I tried creating a ~/.asound.rc containing
defaults.pcm.device 2
but this didn't seem to do anything.

The "Front" channel isn't the same thing as the front panel. From the ALSA wiki:
"Front, Surround, Center, LFE (subwoofer) and Side (these are the names of the channels with Intel HD Audio, they may vary with different hardware)."
How many sounds cards do you have?

What are the other HDMI devices? The video card?
And have you tried googling the problem?

  • Printing only works from one computer

    I have an Epson Stylus C60 connected to the USB port on my Airport Extreme. There are two computers on the network, a PowerBook G4 and a MacBook Pro. Both computers connect to the network very reliably and have internet access. The problem is that the MBP cannot print to the connected printer. The G4 has always printed fine.
    The MBP sees the printer as a Bonjour printer, and I can add it to the printer list without problem. When I try to print, I get a message in the print queue that there is a communications error with the printer.
    In the airport configuration window, the printer is recognized and remote printing is enabled. Any idea why printing only works from the G4?

    Thanks for your help. Yes, the driver is a universal binary and the printer works great when plugged directly into the computer. I just can't figure out why it won't work over the airport.
    Any other ideas?

  • Nokia 6600 only works from one cell tower

    I have this weird problem with my phone where it will only work off one cell tower. Once I leave the coverage of that cell tower it will not work anywhere else.
    It started a few months ago and i'm not to sure why?
    The funny thing is it's the cell tower on top of my building at work, so when i'm at work it will work (calls/txt/etc) but as soon as I go home or even go to another city it will not.
    Any ideas?

    The first thing I'd recommend you do is to reset your phone, but I can't tell from the 6600's webpage what OS you're running so I can't give you instructions on how to do this.
    Have a look through your menus to see if you can find an option to reset to factory defaults, but please remember that doing so will wipe ALL data from your phone.
    If you wish to backup your data you can do so using the PC Suite application which you can find here :

    Hope this helps.

  • 5.1 Surround Sound only outputting from one speaker on macbook

    I have connected my old LG LH T360SE home cinema system to my white 13" macbook (late 2007) from the headphone jack via an audio Y cable into the RCA audio input on the back of the home cinema system. Unfortunately when playing movies via Plex, VLC or any other media player the sound only outputs through the front left speaker and sub-woofer. I checked that the other speakers are connected by perfoming a connection test in the product's setup and there is some background noise if you put your ear up against them. The 5 speakers work fine when playing a DVD on the integrated DVD player. Is there any settings on the macbook I need to change to make use of the full 5.1 surround sound?
    Thanks

    You'll need to use an optical cable to get 5.1 surround. So you'll also need a little optical->mini-optical converter (which allows you to plug it into the 3.5mm jack).

  • Why does usb headset only work in one port?

    I have a 2011 macbook pro 17" laptop with 3 USB ports.  My headset only works in 1 of them (on the right side).  Why is this?  (In case it matters: I am using this headset with my computer as  telephone using Google voice/chat.)

  • Sound only works in one ear

    My ipod just stopped playing in the left ear for no reason. I haven't dropped it or anything. It's not the headphones, I have tried the same headphones on other electronics and they play fine. I have tried multiple pairs of headphones and they all only play in one ear

    its your audio jack...its happened to my ipod before...you can buy one for real cheap on ebay...they go for no more than 10 bucks...you have to install it yourself though...its not that hard just that theres alot of little screws

  • Sound only plays from one application at a time

    I've been having a problem recently with my laptop where it will play sound just fine, but only for one application.
    Explained differently, if I try to start anything that would play sound, and if something else is already playing sound, there won't be any sound from the newer source, and if I want it to play sound, I would have to mute the first source and restart the second.
    Another oddity to this problem is that I can work around this problem by first muting the first source, then starting up the second source, and un-muting the first. This can also be done with additional sources by muting everything that came before it. However, this does not work in every case, and having to do so everytime is rather tedious. I've looked for a few solutions already (Checking drivers, etc.) but nothing seems to work.

    Hi V07,
    Here is what I've notice when Im playing a video sound using K-Lite Codec [Media Player Classic] then while the sound plays on the background. I started to play the game LOL (Leagua of Legends) and it provides me both sound the LOL and video sound with no issues.
    I tried playing video using Media Player Classic and open another video using VLC Player both of this application works fine with no conflict. Both of the player provide good quality sounds.
    You can try installing K-Lite Codec [Media Player Classic] and VLC player.

  • Sound only coming from one speaker on Macbook Pro Retina

    I recently discovered, due to the lack of saxaphone solo's while listening to DMB, that one side of my speakers doesn't work. No sound comes from the right speaker, resulting in loss basically half of a song. The left side works fine, but zero sound comes from the right. Suggestions?

  • Sound only coming from one speaker

    My son had an iPod Touch 4.  One day, one channel stopped working.  I hooked his earbuds up to my iPhone and both speakers worked.  We hooked different earbuds up to his iPod Touch 4 and  only one speaker played so we figured the iPod jack had gone bad. 
    Today, he won a brand new iPod Touch 5 from a contest at our church.  He sets everything up, syncs up with iCloud and only one speaker is working.  This is using the brand new earbuds that came with the iPod Touch 5.  I call Target, they say to come in to exchange it.  We return the iTouch 5 and get another brand new one.
    On the way home, he begins to setup the iTouch 5 and when he slid the unlock slider, he heard the "click" in both earbuds so we thought everything was great.  We get home, he syncs up with iCloud and low and behold, only one earbud is working.  I plug my Klipsch earbuds into the new iTouch 5 and only one earbud is working.
    What in the heck is going on?  Apparently this has nothing to do with his device, but something within iCloud or iTunes?  Even stranger thing is it only plays one speaker even with Youtube, Video Chat and Netflix. 
    I can "barely" hear music coming out of the speaker that is not working.  It's almost like the audio is panned or faded to one channel.
    Any suggestions?  What would cause one audio channel to stop working when he syncs up to his account?
    Thanks in advance for your help.

    You are pushing the headphones all the way in, or you have a case that is preventing you from doing so. The plastic on the headset jack should be flush with the body of the Touch.

  • Flash only works for one user

    Using IE7. I have three users on my computer. All
    have Administrator level access. Flash only works for one of them.
    When attempting to play a video on YouTube for example it says "You
    either have JavaScrip turned off or an old version of Adobe Flash
    Player."
    JS is turned on and the current version of Flash Player is
    installed.
    So does anyone know what is going on here?
    Thanks

    I was able to fix my problem of Flash only working on user
    account. I did the following two steps to correct the problem:
    1. First uninstall the Adobe Flash Player plug-in and ActiveX
    control by following the instructions stated in
    tn_14157.
    2. Second Download SubInACL from Microsoft to fix permission
    issues that prevent the Flash Player installation by following the
    instructions stated in
    fb1634cb.
    Following the above two steps, fixed my problem of only
    having Flash run on only one user account. Now it runs on all four
    user accounts.
    As a side note: The Flash Player plug-in and ActiveX control
    would not run in user accounts with Limited access. But when I set
    the permission of the user account to administrative, then Flash
    would work.

  • Mouse Track Ball only working in one direction

    Hello,
    My Mighty Mouse is 3 months old and now the track ball is only working in one dircetion.
    When I move the ball forward I hear the distinct sound and the scroll bar on e.g. Safari moves, but when I reverse there is no movement on the screen.
    I don't hear the same sound as when I move the track ball forward.
    I have tried to reboot but no improvement.
    Have someone seen teh same issue? Is the solution to simply replace the mouse?
    Thanks / Christer

    Use the instructions in this article to clean the mouse.

  • Can only connect from one direction

    I'm having trouble video confrencing... I tried searching the forums, but I'm having trouble thinking of clever search terms.
    I can only connect from one direction with one person. They can invite me to a chat and it works fine every time. However when I invite them it always fails. I can invite other people and it works fine though.
    This doesn't seem like a typical router problem, because they can invite me and we videochat just fine.
    This has been a problem for most versions of iChat that I can remember, but I'm using 3.1.5 currently.

    Hi
    Is the other person a PC user.

  • Ipod only works in one ear. PLEASE HELP!!!!!!

    My first generation ipod touch only works in one headphone. I've tried 10 different pairs of headphones but with all of them the sound only plays in the left ear. It works in both speakers when i plug it into the speaker that connects to its wider slot (the opening on the ipod next to where the headphones are plugged in) but when i use a cord that connects to the headphone slot that lets me play my ipod on my cars speakers it only works on the left side speaker.
    I don't know what's wrong with it and i really need your help, so PLEASE HELP ME!!!!!!!

    This exact thing happened to my first gen touch. Sadly, I don't have good news for you. First side of the earphone jack stopped working. A few weeks later the headphone jack wouldn't work at all. (Using the docking slot along the bottom still worked fine the whole time, just as you said.) Unfortunately it's not possible to replace the headphone jack without replacing other major components inside the touch so it's very expensive to repair. I could not fix the problem and had to buy a new touch.

  • Mouse only working in one USB slot

    This is more of an anoyance than a problem. I've recently purchaced a Logitech wireless mouse. It has one of those dongle things that you plug into the USB port. The only problem is, that it only works in the one port (one closest to the power). This happens in OS X and in Windows XP. I've tried it on an indentical machine and it works in both. Does anyone have any suggestions.
    Oh, memory sticks / usb hdds etc work in both slots fine...
    Thanks in advance for any help...

    Ok, after reading a few other posts on here I did the SMC reset thing (take out battery and hold power button down). When I booted up the mouse worked in both slots. After a re-start it's back to the same place again, only working in one slot. Any advice on what I should do next?
