Public bug reported: As per this meta-bug: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1002978
Reporting for Lenovo IdeaPad Yoga 13. Inverted channel is visible when recording stereo in audacity. Mono recording via pulseaudio gives silence witch occasional cracks somewhat corresponding to the sound level around. Skype and pavucontrol level gauges are also affected. Changes in balance in pavucontrol do not help with mono recording, I don't know why. I'm attaching two patches against oem-audio-hda-daily- dkms-0.201310111402~ubuntu13.10.1 (https://launchpad.net/~ubuntu-audio- dev/+archive/alsa-daily); either of them fixes the problem for me (the -alt one may affect other hardware, though). No additional steps were needed after applying a patch, building and installing the package. Output of alsa-info.sh is also attached. ** Affects: alsa-driver (Ubuntu) Importance: Undecided Status: New -- 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/1239392 Title: Lenovo IdeaPad Yoga 13: Inverted Internal microphone (phase inversion) Status in “alsa-driver” package in Ubuntu: New Bug description: As per this meta-bug: https://bugs.launchpad.net/ubuntu/+source/alsa-driver/+bug/1002978 Reporting for Lenovo IdeaPad Yoga 13.
