#648: Only 2 channels detected on echo3g devices

-----------------------+----------------------------------------------------
 Using '''module-udev-detect''', my 6-channel sound card (Echo Audio Gina
 3G) is detected only as a stereo device, even though the daemon.conf
 setting ''default-sample-channels'' is set to 6.

 The horrible workaround to resolve the issue is manually adding the alsa
 sink as follows:
 {{{
 load-module module-alsa-sink device=hw:0,0 tsched=0
 load-module module-alsa-sink device=hw:0,1 tsched=0
 }}}

 Of course that defeats the purpose for even having PulseAudio, because now
 I have to make sure the sound card always gets the same index (which is
 still problematic even in most recent distributions) and I cannot use the
 udev-detect module, because it doesn't understand that I've already
 defined this sink manually and duplicates it (as stereo).

 Here is my aplay -l output:
 {{{

 The driver I am using is ''snd_echo3g''.
 If more information is required, please tell me and I will gladly provide
 it.
