Otherwise it results in a silent headphone output. This patch simply resets the hp_detect flag to fix the problem. Have you ask the author the meaning of "driver shouldn't do any software-toggling of pins" ? did the headphone Jack control change to ON when you plugged the headphone Jack ? try hda-jack-sense-test when you plugged the headphone and Mic to find out which node is your Mic ? as there is only one master playback volume which control the volume of stereo speaker and headphone, pre volume control for the subwoofer Simple mixer control 'Master',0 Capabilities: pvolume pswitch penum Playback channels: Front Left - Front Right Limits: Playback 0 - 31 Mono: Front Left: Playback 31 [100%] [0.00dB] [on] Front Right: Playback 31 [100%] [0.00dB] [on] Simple mixer control 'LFE',0 Capabilities: pvolume pvolume-joined pswitch pswitch-joined penum Playback channels: Mono Limits: Playback 0 - 31 Mono: Playback 31 [100%] [0.00dB] [on] -- You received this bug notification because you are subscribed to the bug report. https://bugs.launchpad.net/bugs/1225793 Title: [CF-74ECBAXBM, SigmaTel STAC9200, Speaker, Internal] Playback problem To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1225793/+subscriptions -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1225793 Title: [CF-74ECBAXBM, SigmaTel STAC9200, Speaker, Internal] Playback problem To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1225793/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
