Hello, I would like to improve MC13783 driver to be able to control bypass of LineIn (RXINR/L) and feed Analog LineIn stream into ouput Mixer via ADDRXIN flag.

By cleaning-up/rewriting my code, I get the bypass working. Now I will try to put a mixer widget referenced "Mixer, Adder, Balance" in "Audio Ouput Section Diagram" of User's guide to be able to select which analog audio stream will be fed into selector then I will add control to be able to select needed SOC_DAPM_OUTPUT.

Is there a way to defined state of a SND_SOC_DAPM_SWITCH to 1 or 0 by default ?

This first step one is for test purpose but I also need to select RXINR/L as capture source (I saw in RM that CODEC must be enabled and only RXINR flag must be selected as input) but nothing seems to be captured this is why I need bypass working to test input level, and so on.

I try to create a Mixer based on other driver but it doesn't work. I try to finc information about widget macro SND_SOC_DAPM_* but it is hard to find something relevant.

• Which widgets can be link together ?
• Is there functional difference between VIRT and non-VIRT widget ?

I will post my code in some minutes after clean-up.

Thanks a lot. Gaëtan Carlier.

Thanks, Gaëtan Carlier.
