[alsa-devel] [PATCH] ASoC: codecs: tas2552: fix dBscale-min declaration
The minimum volume level for the TAS2552 (control register value 0x00) is -7dB however the driver declares it as -0.07dB.
Running amixer before the patch reports: dBscale-min=-0.07dB,step=1.00dB,mute=0
Running amixer with the patch applied reports: dBscale-min=-7.00dB,step=1.00dB,mute=0

I have not noticed this when fixing the mute parameter.
