# modprobe -r snd-hda-intel

# modprobe snd-hda-intel

...then sound comes back, and pin-ctls OUT HP are again set to IN

Thanks for the bug report, liakop. If this is still a problem in Edgy, please attach the information requested at https://help.ubuntu.com/community/DebuggingSoundProblems

Thanks

I'm running Feisty and have a similar problem, reported in bug #100114.

[Andrew Ash (ash211)]

bug 100114 seems to be more complete and includes a patch, so I'm marking this a dup of it.

[wvengen (wvengen)]

Thanks for your reaction. One comment though, bug #100114's diff is no source code patch, just a difference in the output /proc/asound/card0/codec#0 before and after suspend (like here).

[Andrew Ash (ash211)]

Yes, I saw that mistake when read what I had said right after I marking the dup!

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this linux-source-2.6.15 kernel bug to the new "linux" package. We appreciate your patience and understanding as we make this transition. Also, if you would be interested in testing the upcoming Intrepid Ibex 8.10 release, it is available at http://www.ubuntu.com/testing . Please let us know your results. Thanks!
