After upgrading to 12.04 today, all aspects are normal, but when you want to listen to songs,

Start using headphones and find that even if the volume is adjusted to the maximum, it is still 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., but I had another operation, namely, pressing F6: Select sound card and re-selecting 0 HDA Intel (the notebook has two sound cards and one is included in the video card ). I don't know which operation works now, but the sound of the headset is there ~~~
