Title:
[900X3G, Realtek ALC282, Mic, Internal] inverted mic not working
Status in “alsa-driver” package in Ubuntu:
Confirmed
Status in “linux” package in Ubuntu:
Confirmed
Bug description:
Internal Mic of Samsung Ativ book 9 (NP900X3G) is not supported
properly.
Stereo recording in audacity records sound from mic in L channel and only
loud noise in R channel (phase inverted?)
Muting R channel, and setting L channel to around 16%, in pavucontrol allows
to record audio, but in poor quality.
