Subject: [PATCH] ASoC: codecs: tas2552: fix dBscale-min declaration
Date: Mon, 05 Oct 2015 20:00:14 +0000 [thread overview]
Message-ID: <1444075214-21206-1-git-send-email-dannenberg@ti.com> (raw)
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
