- Say Y here if you want to use the Atmel AT73C213 external DAC. This
- DAC can be found on Atmel development boards.
- This driver requires the Atmel SSC driver for sound sink, a
- peripheral found on most AT91 microprocessors.
- To compile this driver as a module, choose M here: the module will be
- called snd-at73c213.

- Sets the target bitrate for the bitrate calculator in the driver.
- Limited by hardware to be between 8000 Hz and 50000 Hz.
- Set to 48000 Hz by default.
