Thank you for the input Raymond. I am trying to use your observations to experiment with the sound driver. Unfortunately without success. I have not received any answer from ALSA developers or the patch developers either. However, I followed your instructions and plugged earphones to the computer. It works fine after I change the device in "sound settings" to "Analog Stereo Output". Of course, the same settings do not work on the internal speaker.
