The left channel on my laptop and desktop seems to have stopped working properly under Linux. I've tried two different flavors of the same distro, ubuntu 710 and 704.
Here's a summary of the problems:
Laptop: 704 = weak left channel, 710 = no left channel at all
Desktop: 704 = normal left channel, 710 = weak left channel
By "weak", I mean the volume is considerably diminished compared to the right channel. It does not matter what the source of the sound is (system sounds, xmms, flash player, etc)
By "no left channel" I mean when the balance control is set to 100% left, no sound can be heard from the system at all.
I've checked the volume control under gnome, as well as alsa mixer and verified that both channel volumes are set the same. The laptop is a Centrino Duo based chipset and processor, the desktop is a Core 2 Duo based chip and processor (both of the 965 variety I believe). The sound chipset is reported as "Intel HDA", not sure what version or model. The laptop is a HP Compaq nc6320 and the desktop is a Dell Optiplex GX745.
Any suggestions of things to try, do I need to post up pages and pages of output from tools such as lspci -vvvvv ?
