Other Parts Discussed in Thread: PCM1863
Hi, I have a soundcard in a RaspberryPi device which uses the PCM1863 chip with a mono microphone input. At present that mono microphone signal only appears in the left audio channel later in the system. If my understanding of the datasheet is correct, I can figure the DSP2 functionality to send the ADC1L output to both MIxer1 and Mixer2 output channels, which ?should? make it appear in both left and right audio channels. However I can't see a control parameter in the ALSA configuration to acheive these settings. ( I can see control parameters for the PGA Gain settings for each of the Left and Right channels, but not to select which of the DSP2 inputs is selected.)
Thanks for any guidance you can offer.
Regards,
Peter Stewart
