Title:
[To be filled by O.E.M., Realtek ALC892, Pink Mic, Rear] Underruns,
dropouts or crackling sound
Status in alsa-driver package in Ubuntu:
Incomplete
Bug description:
All sound recorded through the integrated soundcard microphone port
crackles somewhat and has extra background noise. Recording from a
USB-webcam microphone produces clear sound. I've installed the alsa
dkms but this did not help, neither did switching position reporting.
