lspci for kernel 3.15.6
It looks like HDA intel audio is incorrectly detected as Conexant CX20561 [ 15.060156] sound hdaudioC0D2: CX20561 (Hermosa): BIOS auto-probing. [ 15.060614] sound hdaudioC0D2: autoconfig: line_outs=1 (0x1a/0x0/0x0/0x0/0x0) type:speaker [ 15.060618] sound hdaudioC0D2: speaker_outs=0 (0x0/0x0/0x0/0x0/0x0) [ 15.060620] sound hdaudioC0D2: hp_outs=1 (0x16/0x0/0x0/0x0/0x0) [ 15.060623] sound hdaudioC0D2: mono: mono_out=0x0 [ 15.060625] sound hdaudioC0D2: inputs: [ 15.060628] sound hdaudioC0D2: Internal Mic=0x1d [ 15.060630] sound hdaudioC0D2: Mic=0x18 [ 15.061311] sound hdaudioC0D2: Enable sync_write for stable communication It turned out to be a PulseAudio bug which wrongly detects headphone as plugged-in and set Speaker Volume to 0% and Headphone Volume to 100% If so, I'd strongly suggest taking this upstream to bugzilla.freedesktop.org pulseaudio component. I'm not sure yet if it's PulseAudio bug or alsa bug. PulseAudio gets a notification from alsa about headphone plugged-in or unplugged. Maybe the notifications from alsa are not good. It solved itself. |
