Title:
Can only use half the sound range without overdriving sound
Status in pulseaudio package in Ubuntu:
Confirmed
Bug description:
On a Nvidia CK804 (Asus A8N SLI Premium), the audio can only be set to
"base" (63 %) without overdriving the sound. This is because 0db (100
%) is reported wrong in pulseaudio; when seen in alsamixer it actually
sets PCM to 12db, causing distortions.
According to PulseAudio this is a bug in the alsa driver
http://lists.freedesktop.org/archives/pulseaudio-discuss/2012-April/013249.html
http://www.freedesktop.org/wiki/Software/PulseAudio/Documentation/User/PulseAudioStoleMyVolumes/
"If you are experiencing distortions/clipping even though the inner
volumes are set to 0dB, then this means that the dB information your
ALSA driver exports is simply incorrect. In this case please file a
bug against your audio driver and ask them to correct (i.e. shift up)
the volume scale of that volume control."
