** Description changed:
+ Symptom:
+
+ Internal speaker output works on boot, but after some seconds of
+ silence, or after suspend-resume, internal speaker stops working. When
+ analyzing alsa-info, the internal speaker pin's Pin-Ctl is "0x0" instead
+ of "0x40: OUT".
+
+ Patch that needs backporting:
+
+
http://git.kernel.org/?p=linux/kernel/git/tiwai/sound.git;a=commit;h=f7f4b2322bf7b8c5929b7eb5a667091f32592580
+
+ Current workaround:
+
+ Installing https://wiki.ubuntu.com/Audio/UpgradingAlsa/DKMS will resolve
+ the problem. Also turning off "Automute mode" in alsamixer might help
+ for some people.
+
+ =======
+
My speakers and sound work fine, including internal speakers and HDMI
digital out. When I suspend by closing the lid, then open the lid,
there is no sound until reboot.
