[yocto] Help configuring pulseaudio

[Gary Thomas]

I know this is a little off-topic.  I have a Poky/Yocto
based system running pulseaudio out of the box.  Output
(playback) works great,  but it is choosing the wrong
device for input.  I'm hoping someone can give me a pointer
on how to configure things to get the input correct.

Here are my devices (raw ALSA version):

Here's what pulse is choosing:
   # pactl stat
   Currently in use: 1 blocks containing 64.0 KiB bytes total.
   Allocated during whole lifetime: 59019 blocks containing 41.4 MiB bytes total.
   Sample cache size: 0 B

   Default Source: alsa_output.platform-omap-abe-twl6040.analog-stereo.monitor

What I want is for it to choose the ALSA device hw:0,1 for input (source).

Can someone help out?

Thanks
