Status changed to 'Confirmed' because the bug affects multiple users.

Same issue same codec,

# cat /proc/asound/card0/codec#* | grep Codec
Codec: Conexant CX20590
Codec: Intel PantherPoint HDMI

Read somewhere that Conexant 506e/20590 has the same graph as the rest of the 5066 family, so tried all the model options listed for the 5066, one by one (from alsa kernel docs and from alsa-base docs). "laptop" and "dell-laptop" only disable the audio out jack, and "olpc-xo-1_5" and "ideapad" don't seem to make any change (volume is still way too low below 80%, and 100% is not as loud as it should be)

Using this as a work around: https://wiki.archlinux.org/index.php/Advanced_Linux_Sound_Architecture#Low_Sound_Workaround

Forgot to mention, Dell Inspiron 15R / 5520 - ci5

The ALSA Pre-Amp workaround I mentioned prior isn't really that good. 1. It requires nuking pulseaudio altogether 2. the amplification really distorts the sound.

The only decent workaround is to install pavucontrol and control volumes for applications above 100% (increases dB gain)
