Ubuntu12.04 audio solution for headphones with silent speakers

Today, I upgraded to Ubuntu12.04, which is normal in all aspects. However, when I wanted to listen to the songs, I started to use headphones and found that even if the volume was adjusted to the maximum, I still remained silent. Later, I pulled out my earphones and found a sound. That may be where the configuration is incorrect. Solution: Run alsamixer on the terminal, move the cursor to the Headphone, and move up. However, one more operation was to press F6: Selectsoundcard and select 0HDA again.

Move the cursor to the Headphone and move it up. However, one more operation was to press F6: Select sound card and re-Select 0 HDA Intel (two sound cards in the notebook, one in the video card ). I don't know which operation is working, but the sound of the headset is there.
