    Only one ear works on earphones


    Hello All,

    I've had this strange issue pop-up and was wondering if someone could help me figure out what's going on.

    I dual boot Ubuntu 12.04 LTS. When I got the machine about a year ago, the earphones worked fine on both Ubuntu and Windows. About a month later the earphones only worked sporadically on Windows. However, on Ubuntu they worked without a problem, for probably 8 months.

    But, over the last two months, Ubuntu will only play out of one ear. Every once in a while I get Windows to work with the earphones, and when it does, it plays both ears.

    I understand command lines etc, but don't really know how to diagnose this problem--is it a sound card malfunction, is it a software malfunction? I'm not sure how to determine this.

    Any help or suggestions would be greatly appreciated!

    Thanks!

    Good thought--my first one. But it does it with any earphone used, which makes me think it is either software or hardware. Thanks though!

    The strange thing is that, when it works in Windows, both ears work, but when in Ubuntu it always works, but only one ear. I'm starting to guess that maybe it is a hardware problem, but I've no idea how to diagnose this.

    I just noticed that the "Balance" for the headphone settings gets shifted towards the right ear whenever the earphones are plugged in. That's really wierd,but it seems that if I just manually move it back to center the left ear turns on as well. I guess this can be marked as solved, but it's still not clear why the balance moves when the earphones are plugged in. For example, if I restart the computer and plug in my headphones, the balance gets shifted again.

    Anyway, main problem solved. Thanks for anyone who gave any thought!

    I did wonder if a channel was muted or something similar but thought it couldn't be that simple! It may be worth having a look at alsamixer to see if the settings there need adjusting. To run it open a terminal and simply enter alsamixer* and once it is running you navigate with the left and right cursor keys and adjust the settings with the up and down keys. Depending on your sound card, not all the controls may be on one screen.
