More details with some current tests: Tests made with both audacity and the Volume Control ... 'stereo' set throughout and everything fully activated. volume control shows background/static input that can be increased with the sliders.
Tests with Audacity: Set to 'ALSA' ... Speaker and Microphone set to 'default' ... Same both 'Mono' and 'Stereo' Pressing mic. symbol shows a base static? input all the time. Does not change during record. During playback process a base low 'static' can be seen. Mic ON/OFF button does not work but tried in both positions. I did patch this problem and found that even with an indicator the difficulty remains. Just did a system upgrade and the patch is now gone!! On Alsamixer: Turning the headphones on/off makes no change Other settings are 'unmuted' (00) and set to 100% Sound card set to 'default' =HDA Intel PCH Capture: L and R = 100% Dock not activated and muted David On 13-11-21 05:20 PM, Raymond wrote: > did you record in stereo or mono when using audacity ? > > are the left and right channels out of phase for your digital mic ? > > Simple mixer control 'Headphone',0 > Capabilities: pvolume pswitch > Playback channels: Front Left - Front Right > Limits: Playback 0 - 87 > Mono: > Front Left: Playback 87 [100%] [0.00dB] [on] > Front Right: Playback 87 [100%] [0.00dB] [on] > Simple mixer control 'Headphone',1 > Capabilities: pswitch > Playback channels: Front Left - Front Right > Mono: > Front Left: Playback [on] > Front Right: Playback [on] > -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to alsa-driver in Ubuntu. https://bugs.launchpad.net/bugs/1253803 Title: [2436CTR, Realtek ALC269VC, Mic, Internal] No sound at all Status in “alsa-driver” package in Ubuntu: New Bug description: Xubuntu 13.10 All settings of alsamixer set to max volume including microphone boost.
