[opensuse-kernel] Headphones work with Kernel 3.8, but not kernel 3.9--Speakers OK on both
When I upgraded the kernel to 3.9, for some reason I get no sound through the headphones, but the speaker works fine. I went through the typical troubleshooting steps, e.g. editing /etc/modprobe.d/50-sound.conf, with no luck. So I tried the earlier kernel and much to my surprise, it worked! I did an lsmod on both kernels and they both have the same modules loaded, though as expected the 3.9 modules are of different sizes. I suspect there is an issue with the drivers, but I really don't know how to procede at this time. My sound card/mixer settings are OK because everything works with kernel 3.8; the ONLY difference is the kernel and some of the modules. I have the ICH9 chipset. Here is the output of the ALSA debug: 3.9 Kernel http://www.alsa-project.org/db/?f=7ce3c0a19dde078619a3c16bb8fce1f861226679 3.8 Kernel http://www.alsa-project.org/db/?f=1b5e4d7aaf024caed25c47f6f9c7645608ad5106 I have a bug opened with ID 818828 -- Edward Reiss <ebreiss@gmail.com> -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org

Have you tried disabling pulseaudio? And then checking with alsamixer the settings for the channels after using F6 to set your audio card? If you must have pulseaudio, do you have pavucontrol installed (and the headphones selected)?
