I'm using an ADAU1761 codec in a project, but we'd like, for now, to use it just as a mixer, i.e. without passing through the ADC/DAC and DSP stages.
Which is the best way of accomplishing that?
In the past I tried to add virtual DAPM routes in order to get the relevant power systems powered up, and bypassing the standby modes, since the device wouldn't let me use the mixer controls through I2C if I don't clock it.
Another question: how do I tell ALSA to power up a stage (in this case, the ALC/differential input stage)?
TIA, Matteo
