Problem with sound panp5 ubuntu 10.10

Asked by doubletruncation on 2011-06-13

I have not been able to hear sound out of my laptop speakers or headphones. I hear the drum sound when the login screen loads up, but after starting gnome I do not get sound when I set the hardware to "Digital Stereo (IEC958) Output + Analog Stereo Input". I do hear sound when I set it to Digital Stereo (HDMI) Output and connect a speaker system to the HDMI output. I have checked alasmixer to ensure that nothing is muted, I have also done the System 76 restore system, and upgraded to ubuntu 10.10 (I initially had this problem with 10.04).

aplay -l gives

Sorry about the problems you're having with the sound on your laptop. First, click on the "Internal Audio" Item in the hardware tab ans set that to "Analog Stereo Duplex". This will set up the sound card to output through the speakers and headphones. Then, on the "Output" tab, make sure that "Internal Audio Analog Stereo" is selected as the output device.

Thanks that worked. I had tried using Analog Stereo Duplex before, but then didn't check to make sure that the speaker was not muted in alsamixer (it was).
