Description:
After upgrading from linux-3.8.11-1 to linux-3.9.2-1, mute/unmute no longer works in amixer or alsamixer. It works again if I downgrade the linux package.


Hardware:
This is a Lenovo ThinkPad T500. Relevant hardware:

[d@eighth ~]$ lspci | grep -i audio
00:1b.0 Audio device: Intel Corporation 82801I (ICH9 Family) HD Audio Controller (rev 03)
[d@eighth ~]$ cat /proc/asound/cards
0 [Intel ]: HDA-Intel - HDA Intel
HDA Intel at 0xfc020000 irq 46
29 [ThinkPadEC ]: ThinkPad EC - ThinkPad Console Audio Control
ThinkPad Console Audio Control at EC reg 0x30, fw 7VHT12WW-1.01


Steps to reproduce:
On linux-3.8.11-1, amixer behaves normally:

[d@eighth ~]$ amixer set Master mute
Simple mixer control 'Master',0
Capabilities: pvolume pvolume-joined pswitch pswitch-joined
Playback channels: Mono
Limits: Playback 0 - 74
Mono: Playback 35 [47%] [-39.00dB] [off]

After upgrading to linux-3.9.2-1 and rebooting, mute/unmute no longer works:

[d@eighth ~]$ amixer set Master mute
amixer: Invalid command!


Workarounds:
1. Set volume to 0% instead of muting: amixer set Master 0%
2. Downgrade to linux-3.8.11-1
3. Switch to linux-lts
This task depends upon

Another workaround: use PulseAudio by adding start-pulseaudio-x11 to ~/.xinitrc.
