Hello All:
I have a new Toshiba P855-S5200=2C and although Windows 7 creates sound on
the internal speakers, OpenSuse 12.1 and Tumbleweed (which I was forced to by
bug 769678) are silent. I suspect this is because the hardware's design is new
and additional kernel support is required. For full disclosure I also opened an
OpenSuse 12.1 ticket for this at
https://bugzilla.novell.com/show_bug.cgi?id=3D769991.
Regarding the symptoms I see, my system acts like the sound device is
detected but no sound (speakers or headphones) is generated. My laptop has
internal speakers, microphone and headphone jacks and HDMI. I have not tried HDMI.
I noticed some discussion about a patch that sounds like it might address
this issue at:http://www.spinics.net/lists/stable-commits/msg18206.html
If the maintainers agree that this is a likely fix=2C could we please try it?
I'm not sure how to build and deploy a kernel in OpenSUSE, but I would be
willing to test the fix in the Tumbleweed version of the kernel.
My current kernel is 3.4.3-30-desktop.
The uname -a kernel info and the /proc and lscpi information about
the device are as follows:
