#304: loading both module-alsa-{sink,source} fails

 Priority:  normal         |   Milestone:         
Component:  module-alsa-*  |    Severity:  normal 
 Keywords:                 |  
---------------------------+------------------------------------------------
 If I try to load both module-alsa-sink and module-alsa-source, whichever
 one is latter in the default2.pa file fails with a 'device or resource
 busy' message

 But, If I comment one of the modules, the other will load without
 problems.

 I don't know if this is an alsa, or pulseaudio bug, but I thought I'd try
 my luck here first...

 I ran pulseaudio with: `pulseaudio -nF .pulse/default2.pa`

 default2.pa contains the following:
 {{{
 #!/usr/bin/pulseaudio -nF

 load-module module-alsa-sink
 load-module module-alsa-source

 load-module module-native-protocol-tcp auth-anonymous=1 port=4777
 #load-module module-zeroconf-publish
 }}}

 This is on a thinkpad 760el (w/ snd-es1688) running debian
 unstable/testing, with pulseaudo 0.9.10.

 pulseaudio output:
