No sound from headphones
« on: July 25, 2014, 12:46:34 am »
No sound from headphones. Sound from speaker is working. I have a dual boot and headphones works fine in Win7, just checked.

Everything appears to work. The headphone device description in the drop down box changes from unplugged to plugged-in as I do so. Everything looks the same as when I hear sound on the speakers.

This is what I am seeing in the Pulse Audio Volume Control application:



             

                           

Any suggestions would be appreciated.

Here's some configuration info, if that would help:

Run:

After researching on the web, and further understanding how alsamixer works, I think I fixed it when I disabled 'Auto-Mut'. Thank-you!
