Subject: Soc MC13783: Improve driver to handle LineIn
Date: Thu, 24 Jan 2013 10:42:22 +0100 [thread overview]
Message-ID: <510101FE.4060307@gmail.com> (raw)
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.
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.
