Sound comes from right speaker only. Already checked volume.

Hi all, I just unboxed my aa1 today and I'm having problems with the sound only coming from one speaker and headphone. I've already checked alsa-mixer to make sure a setting isn't wrong and that it isn't muted but everything there seems to be fine. I've tried searching the forums and google, but haven't found anything, is this a known software issue or is it more likely hardware.

(I'm leaning towards software because sound only comes out of one earphone also.)

Running Linpus, 1GB ram, 16GB SSD. Model number AOA110-1626

 

2 things first. Are you sure you have the plug inserted completely? If so try rotating it. Are you sure the headset works properly on a good connection?

 

Yes. I tested two different headsets and I could hear sound in both when fiddling with it one time, but that just means I was able to cross the connections.

I'm more worried about the left built-in speaker not working. If I can get that working, the headphones should work too.

 

Sound works fine for me with both channels. Post the output of amixer.

Microphone works perfectly.

 

The output looks fine. I suggest you test out the sound with a more capable pendrive distro to rule out or confirm software as being the cause.

I don't have Linpus installed anymore so I can't do any testing.

 

I just tested the sound using Ubuntu live and it worked. I then decided to test one more time in Linpus and it worked. I guess the problem was fixed by something that applied between restarts.

Thanks for the help.
