Speaker Output barely audible across multiple distros (same machine)

When tested 5 channels, the output "CENTER" is markedly louder, though audio is still very low. "Front Left" and "Front Right" are barely audible. Rear channels yield silence when tested.

I suspected something like this might be the case.

Can you please post the output of the following command?

Code:

pacmd list-sinks

Also, perhaps

Code:

pacmd list sinks|grep output:

*Note: no hyphen between 'list' and 'sinks' this time

Returning to the noetebookreview.com page linked to by camorri back in post #8 I note a couple of suggestions that you didn't appear to list as digested in post #10. They might be worth a shot...

1) Post #31 of the thread.

Quote:

Necessary to remove the back cover of visible battery backup! Circuit the battery terminals on the board for 2 seconds, connect the battery! INCLUDES and sound is heard !!!!!!!!!!!!!!!

Slightly more refined - Shut the machine down, locate and remove the CMOS backup battery for several seconds. (Short-circuit the terminals to discharge any capacitors?). Then reinstate and boot again. See if the sound level is any different.

2) Post #48 of the thread.

Quote:

The method is (without anything plugged into external jack of course):
1) play something that has audio (eg - an mp3, youtube video, whatever) and confirm the computer thinks sound is playing
2) while the sound is still "playing" (though you cannot hear it), put the PC to sleep via the regular methods of doing so (both shutdown menu/sleep and closing the lid when set to sleep appear to work fine).
3) when you resume the pc it appears to initialise the built in speaker as expected and it will play sound
