Comment 93 for bug 428619

your cs46xx have dual ac97 codecs CS4297A and CS4294

There are two "Master Playback Volume" controls, I guess PA mis calculate the dB range -129.00 dB to 12.00 dB.

I: sink.c: device.description = "CS 4614/22/24/30 [CrystalClear SoundFusion Audio Accelerator] Analog Stereo"
I: sink.c: alsa.mixer_name = "Cirrus Logic CS4297A rev 4,Cirrus Logic CS4294 rev 5"
I: sink.c: alsa.components = "AC97a:43525914 AC97a:4352592d"
