[alsa-devel] AIC23 playback volume control not working

[Aggarwal, Anuj]

Hi,

I am trying to change the playback volume using amixer commands but
am not able to see any effect. Register writes are happening correctly
but no change in volume. Here is a short log:

root at omap3evm:~# amixer cset numid=1 0
tlv320aic23_write: reg=0x2, value=0x0
data[0]=0x4, data[1]=0x0
tlv320aic23_write: reg=0x3, value=0x0
data[0]=0x6, data[1]=0x0
numid=1,iface=MIXER,name='Digital Playback Volume'
  ; type=INTEGER,access=rw---R--,values=2,min=0,max=127,step=0
  : values=0,0
  | dBscale-min=-121.00dB,step=1.00dB,mute=0

  : values=127,127
  | dBscale-min=-121.00dB,step=1.00dB,mute=0

Any suggestions are appreciated.
