Looking for some help as I have already posted in numerous help forums and was still unable to resolve an issue.
System Info: HP Probook 6470b (Ubuntu 14.04 LTS and Win7) Intel Corporation 7 Series/C210 Series Chipset Family High Definition Audio Controller (rev 04) Kernel: 3.13.0-37-generic
The Problem: Both audio channels are being played over only the left speaker when booted into Ubuntu while leaving the right speaker silent. Using the test sound ques in the sound settings plays both the 'front left' and 'front right' ques in the left speaker.
What I know/tried: Both speakers are physically capable of functioning as sound is correct when booted into Win7. Headphone audio is correct and functioning with both channels playing on their respective sides. The alsamixer settings are correct and nothing is out of balance or unintentionally muted. The pavucontrol settings are correct and nothing is out of balance or muted. I have also tried all the configuration profiles with no positive change. (Currently set in 'Analogue Stereo Duplex'.)
I would appreciate any kind of help as I am very stumped. I can provide more information as needed relevant to the fix. Thank you, Kent
