# CONFIG_SND_SOC_TEGRA186_DSPK: # # Config to enable the Digital Speaker Controller (DSPK) which # converts the multi-bit Pulse Code Modulation (PCM) audio input to # oversampled 1-bit Pulse Density Modulation (PDM) output. From the # signal flow perspective DSPK can be viewed as a PDM transmitter # that up-samples the input to the desired sampling rate by # interpolation and then converts the oversampled PCM input to # the desired 1-bit output via Delta Sigma Modulation (DSM). # Say Y or M if you want to add support for Tegra186 DSPK module. # # Symbol: SND_SOC_TEGRA186_DSPK [=n] # Type : tristate # Defined at sound/soc/tegra/Kconfig:96 # Prompt: Tegra186 DSPK module # Depends on: SOUND [=m] && !UML && SND [=m] && SND_SOC [=m] && SND_SOC_TEGRA [=m] # Location: # -> Device Drivers # -> Sound card support (SOUND [=m]) # -> Advanced Linux Sound Architecture (SND [=m]) # -> ALSA for SoC audio support (SND_SOC [=m]) # -> SoC Audio for the Tegra System-on-Chip (SND_SOC_TEGRA [=m]) # # # # CONFIG_SND_SOC_TEGRA186_DSPK is not set
