[alsa-devel] [BUG] Bad decibel data on C-Media USB sound card

[Allen M.]

First time bug submitter, forgive me if I'm not following proper procedure.

OS: Arch Linux 64-bit
Kernel version: 3.16.3-1-ARCH

What's happening:
When the Master channel is lowered below 35% in alsamixer,
all audio coming out of the C-Media USB sound card is muted.

Additional info:
PulseAudio is installed
Output of 'lsusb':
   Bus 005 Device 002: ID 0d8c:000c C-Media Electronics, Inc. Audio Adapter
Alsa hw ID name:
   'Set'
Output of 'cat /proc/asound/Set/usbmixer'

Any assistance in resolving the issue is greatly appreciated
