'amixer' can mute the speaker but it cannot unmute it.

[bzb001]

My system:
lubuntu 15.04 64bit
hp laptop model# 15-r174ca

Issue: I can use amixer to mute the audio. Once done, I cannot use amixer to unmute. amixer console output seems ok when commanded to mute and unmute but the audio remain muted. I needed to go to the desktop at the audio applet to unmute the speaker.

$ amixer -c 1 sset Master toggle
Simple mixer control 'Master',0
  Capabilities: pvolume pvolume-joined pswitch pswitch-joined
  Playback channels: Mono
  Limits: Playback 0 - 87
  Mono: Playback 73 [84%] [-10.50dB] [off]
00:33:06:(2),jobs=0,cmd#=3,hist#=66

$ amixer -c 1 sset Master toggle
Simple mixer control 'Master',0
  Capabilities: pvolume pvolume-joined pswitch pswitch-joined
  Playback channels: Mono
  Limits: Playback 0 - 87
  Mono: Playback 73 [84%] [-10.50dB] [on]

This command also fails to unmute the audio.

$ amixer -c 1 sset Master mute
Simple mixer control 'Master',0
  Capabilities: pvolume pvolume-joined pswitch pswitch-joined
  Playback channels: Mono
  Limits: Playback 0 - 87
  Mono: Playback 73 [84%] [-10.50dB] [off]
00:34:53:(2),jobs=0,cmd#=7,hist#=68

$ amixer -c 1 sset Master unmute
Simple mixer control 'Master',0
  Capabilities: pvolume pvolume-joined pswitch pswitch-joined
  Playback channels: Mono
  Limits: Playback 0 - 87
  Mono: Playback 73 [84%] [-10.50dB] [on]

Is this still a problem with the latest Lubuntu Next image?

For now, I will mark this as Incomplete as there is not enough information to reproduce this bug.
